Question

A staff nurse who is promoted to assistant nurse manager may feel uncomfortable initially when supervising her former peers. She can best decrease this discomfort by: A. Writing down all assignments. B. Making changes after evaluating the situation and having discussions with the staff. C. Telling the staff nurses that she is making changes to benefit their performance. D. Evaluating the clinical performance of each staff nurse in a private conference.

Answer 1

Correct Answer: B. Making changes after evaluating the situation and having discussions with the staff. A new assistant nurse manager should not make changes until she has had a chance to evaluate staff members, patients, and physicians. Changes must be planned thoroughly and should be based on a need to improve conditions, not just for the sake of change. Option A: Written assignments allow all staff members to know their own and others’ responsibilities and serve as a checklist for the manager, enabling her to gauge whether the unit is being run effectively and whether patients are receiving appropriate care. Option C: Telling the staff nurses that she is making changes to benefit their performance should occur only after the nurse has made a thorough evaluation. Option D: Evaluations are usually done on a yearly basis or as needed.

Answer 2

Correct Answer: B. Sensory deficits Sensory deficits could cause a geriatric patient to have difficulty retaining knowledge about prescribed medications. Age-related decline of the five classical senses (vision, smell, hearing, touch, and taste) poses significant burdens on older adults. The co-occurrence of multiple sensory deficits in older adults is not well characterized and may reflect a common mechanism resulting in global sensory impairment. Option A: Decreased plasma drug levels do not alter the patient’s knowledge about the drug. Aging has long been associated with decline in sensory function, a critical component of the health and quality of life of older people Option C: A lack of family support may affect compliance, not knowledge retention. Vision impairment is correlated with depression, poor quality of life, cognitive decline, and mortality. Hearing loss is associated with slower gait speed (a marker of physical decline), poor cognition, and mortality. Like smell, taste has been associated with nutritional compromise and in-patient mortality, suggesting that chemosensory function is critical. Tactile discrimination declines with age due to the cumulative effects of decreased nerve conduction velocity, decreased density of Meissner’s and Pacinian corpuscles, and gray matter changes within the central nervous system, and is also associated with cognitive decline Option D: Tourette syndrome is unrelated to knowledge retention. Tourette syndrome referred to as Tourette disorder in the recently updated Diagnostic and Statistical Manual of Mental Disorders (DSM–5), is a common neurodevelopmental disorder affecting up to 1% of the population. It is characterized by multiple motor and vocal tics and starts in childhood.

Answer 3

Correct Answer: C. The symptomatic quadrant last The nurse should systematically assess all areas of the abdomen, if time and the patient’s condition permit, concluding with the symptomatic area. Otherwise, the nurse may elicit pain in the symptomatic area, causing the muscles in other areas to tighten. This would interfere with further assessment. Option A: When possible, the history should be obtained from a non sedated patient. The initial differential diagnosis can be determined by a delineation of the pain’s location, radiation, and movement (e.g., appendicitis-associated pain usually moves from the periumbilical area to the right lower quadrant of the abdomen). Option B: After the location is identified, the physician should obtain general information about onset, duration, severity, and quality of pain and about exacerbating and remitting factors. Option D: There are several specialized maneuvers that evaluate for signs associated with causes of abdominal pain. When present, some signs are highly predictive of certain diseases.

Answer 4

Correct Answer: C. Patient’s description of pain Subjective data come directly from the patient and usually are recorded as direct quotations that reflect the patient’s opinions or feelings about a situation. Subjective data provide clues to possible physiologic, psychological, and sociologic problems. They also provide the nurse with information that may reveal a client’s risk for a problem as well as areas of strengths for the client. The information is obtained through interviewing. Vital signs, laboratory test results, and ECG waveforms are examples of objective data. Option A: Vital sign monitoring is a fundamental component of nursing care. A patient’s pulse, respirations, blood pressure, and body temperature are essential in identifying clinical deterioration and that these parameters must be measured consistently and recorded accurately. Option B: Many other tests are reported as numbers or values. Laboratory test results reported as numbers are not meaningful by themselves. Their meaning comes from comparison to reference values. Reference values are the values expected for a healthy person. They are sometimes called “normal” values. Option D: The standard 12-lead electrocardiogram (ECG) is one of the most commonly used medical studies in the assessment of cardiovascular disease. It is the most important test for interpretation of the cardiac rhythm, detection of myocardial ischemia and infarction, conduction system abnormalities, preexcitation, long QT syndromes, atrial abnormalities, ventricular hypertrophy, pericarditis, and other conditions.

Answer 5

Correct Answer: C. Cool, pale fingers A safety device on the wrist may impair circulation and restrict blood supply to body tissues. Therefore, the nurse should assess the patient for signs of impaired circulation, such as cool, pale fingers. A palpable radial or lunar pulse and pink nail beds are normal findings. Option A: To palpate a radial pulse, place the tips of the first two or three fingers over the groove along the radial (or thumb) side of the patient’s inner wrist. Slightly extended or flexed the patient’s wrist with the palm down until the pulse was strongest. Lightly compressed the artery against the radius, obliterating the pulse initially. Option B: The pulse is felt just above a large, raised bony area called the zygomatic arch. Like the radial pulse, the ulnar pulse is taken at the wrist. Option D: These old cells flatten and harden, thanks to keratin, a protein made by these cells. The newly formed nail then slides along the nail bed, the flat surface under the nails. The nail bed sits on top of tiny blood vessels that feed it and give the nails their pink color.

Answer 6

Correct Answer: A. Frontal plane Frontal or coronal plane runs longitudinally at a right angle to a sagittal plane dividing the body in anterior and posterior regions. The coronal plane or frontal plane (vertical) divides the body into dorsal and ventral (back and front, or posterior and anterior) portions. An anatomical plane is a hypothetical plane used to transect the body, in order to describe the location of structures or the direction of movements. Option B: A sagittal plane runs longitudinally dividing the body into right and left regions. The sagittal plane or lateral plane (longitudinal, anteroposterior) is a plane parallel to the sagittal suture. It divides the body into left and right. Option C: If exactly midline, it is called a midsagittal plane. The midsagittal or median plane is in the midline; i.e. it would pass through midline structures such as the navel or spine, and all other sagittal planes (also referred to as parasagittal planes) are parallel to it. Median can also refer to the midsagittal plane of other structures, such as a digit. Option D: A transverse plane runs horizontally at a right angle to the vertical axis, dividing the structure into superior and inferior regions. The transverse plane or axial plane (horizontal) divides the body into cranial and caudal (head and tail) portions.

Answer 7

Correct Answer: A. Shock dismay Shock and dismay are early signs of denial-the first stage of grief. Denial is a common defense mechanism used to protect oneself from the hardship of considering an upsetting reality. Kubler-Ross noted that after the initial shock of receiving a terminal diagnosis, patients would often reject the reality of the new information. The other options are associated with depression—a later stage of grief. Option B: Depression is perhaps the most immediately understandable of Kubler-Ross’s stages and patients experience it with unsurprising symptoms such as sadness, fatigue, and anhedonia. Option C: Spending time in the first three stages is potentially an unconscious effort to protect oneself from this emotional pain, and, while the patient’s actions may potentially be easier to understand, they may be more jarring in juxtaposition to behaviors arising from the first three stages. Option D: Consequently, caregivers may need to make a conscious effort to restore compassion that may have waned while caring for patients progressing through the first three stages.

Answer 8

Correct Answer: B. Helps the patient dangle the legs After placing the patient in High Fowler’s position and moving the patient to the side of the bed, the nurse helps the patient sit on the edge of the bed and dangle the legs; the nurse then faces the patient and places the chair next to and facing the head of the bed. Option A: Allow the patient to sit for a few moments, in case the patient feels dizzy when first sitting up. To get the patient into a seated position, roll the patient onto the same side as the wheelchair. Option C: The nurse should put one arm under the patient’s shoulders and one behind the knees. Bend the knees. Swing the patient’s feet off the edge of the bed and use the momentum to help the patient into a sitting position. Option D: Move the patient to the edge of the bed and lower the bed so the patient’s feet are touching the ground. Make sure any loose rugs are out of the way to prevent slipping. You may want to put non-skid socks or shoes on the patient’s feet if the patient needs to step onto a slippery surface.

Answer 9

Correct Answer: D. Demonstrating the procedure and having the patient return the demonstration Demonstrating by the nurse with a return demonstration by the patient ensures that the patient can perform wound care correctly. One of the leading causes of medical errors in the United States is miscommunication between patients and providers. When patients with limited English proficiency (LEP) cannot adequately communicate their needs, they are less likely to comply with medical instructions and receive vital services. Option A: Patients may claim to understand discharge instruction when they do not. In-person translation services are preferred when complex medical information or end-of-life decisions are to be discussed. Studies show in-person professional interpretation increases patient satisfaction and outcomes of care. Interpreters use visual cues to enhance communication. However, in-person interpreters can be costly and can limit the number of languages that can be adequately staffed. Option B: An interpreter of family members may communicate verbal or written instructions inaccurately. In some cases, patients prefer to use their family and friends as medical interpreters, but experts recommend against the practice because vital information may be lost. Option C: Internet-based apps for smartphones and tablets help medical professionals interpret information quickly so they can be used in emergency settings. Experts warn, however, that the one-sided nature of such applications can lead to missed or misconstrued information.

Answer 10

Correct Answer: A. Discard the syringe to avoid a medication error. As a safety precaution, the nurse should discard an unlabeled syringe that contains medication. The other options are considered unsafe because they promote error. Option B: Since there are no labels on the syringe, obtaining a label from the pharmacy does not guarantee that they would be able to identify the medication inside the syringe. Option C: Giving an unidentified medication could cause unwanted effects on the patient instead of desired effects. Option D: The day nurse would not be able to guarantee that she could identify the medication without its label.

Answer 11

Correct Answer: B. Aging-related physiological changes Aging-related physiological changes account for the increased frequency of adverse drug reactions in geriatric patients. ADEs are estimated to be indicated in 5% to 28% of acute geriatric medical admissions. Preventable ADEs are among one of the serious consequences of inappropriate medication use in older adults. Option A: Renal and hepatic changes cause drugs to clear more slowly in these patients. Aging leads to a reduced number of functional glomeruli and an increased prevalence of sclerotic changes within the glomeruli or renal vasculature. Additionally, there is a normal decrease in GFR observed in advanced age, but this places the elderly at much higher risk for complications in the event that they develop chronic or acute kidney disease, as they have less functional glomeruli as a result of normal aging physiology. Option C: With increasing age, neurons are lost. Abnormal compensatory mechanisms predispose individuals to neurodegeneration and dementia, Parkinson disease, and overall cerebral atrophy are observable in aging individuals. Option D: Blood flow to the GI tract decreases. The weakening of smooth muscle in the intestinal tract can promote the development of diverticular disease and can play a role in bowel obstructions or constipation. Decreased metabolic activity, specifically in the liver, can lead to alterations in drug metabolism.

Answer 12

Correct Answer: B. Educator When teaching a patient about medications before discharge, the nurse is acting as an educator. They provide educational leadership to patients and care providers to enhance specialized patient care within established healthcare settings. Assists patients and caregivers with educational needs, problem resolution, and health management across the continuum of care. Option A: The nurse acts as a manager when performing such activities as scheduling and making patient care assignments. Great nurse managers are able to work in coordination with other departments. They must also possess the ability to oversee an array of practice functions including staff supervision, clinical tasks, and appointments. It is also part of their jobs to liaise with pathology labs, suppliers, and other health facilities. Option C: The nurse performs the caregiving role when providing direct care, including bathing patients and administering medications and prescribed treatments. Healthcare should address a patient’s cultural, spiritual and mental needs. Increasing diversity in a growing patient population requires nurses to demonstrate cultural awareness and sensitivity. Patients may have specific needs and preferences due to their religion or gender, for example. Nurses need to be respectful of, and knowledgeable about, diverse backgrounds while remaining vigilant in providing quality care. Option D: The nurse acts as a patient advocate when making the patient’s wishes known to the doctor. A nurse advocate is a nurse who works on behalf of patients to maintain quality of care and protect patients’ rights. They intervene when there is a care concern, and following the proper channels, work to resolve any patient care issues. Realistically, every nurse is an advocate.

Answer 13

Correct Answer: D. “Let’s talk about what’s bothering you.” Anxiety may result from feelings of helplessness, isolation, or insecurity. This response helps reduce anxiety by encouraging the patient to express feelings. The nurse should be supportive and develop goals together with the patient to give the patient some control over an anxiety-inducing situation. Because the other options ignore the patient’s feelings and block communication, they would not reduce anxiety. Option A: Recognize awareness of the patient’s anxiety. Since a cause of anxiety cannot always be identified, the patient may feel as though the feelings being experienced are counterfeit. Acknowledgment of the patient’s feelings validates the feelings and communicates acceptance of those feelings. Option B: Converse using a simple language and brief statements. Allow patients to talk about anxious feelings and examine anxiety-provoking situations if they are identifiable. Talking about anxiety-producing situations and anxious feelings can help the patient perceive the situation realistically and recognize factors leading to the anxious feelings. Option C: Assist the patient in developing new anxiety-reducing skills (e.g., relaxation, deep breathing, positive visualization, and reassuring self-statements). Discovering new coping methods provides the patient with a variety of ways to manage anxiety.

Answer 14

Correct Answer: C. Handling surgical instruments to the surgeon The scrub nurse assists the surgeon by providing appropriate surgical instruments and supplies, maintaining strict surgical asepsis and, with the circulating nurse, accounting for all gauze, sponges, needles, and instruments. The circulating nurse assists the surgeon and scrub nurse, positions the patient, applies appropriate equipment and surgical drapes, assists with gowning and gloving, and provides the surgeon and scrub nurse with supplies. Option A: The circulating nurse is responsible for managing all nursing care within the operating room, observing the surgical team from a broad perspective, and assisting the team to create and maintain a safe, comfortable environment for the patient’s surgery. Option B: A circulating nurse is responsible for coordinating care, obtaining supplies, and liaising with the patient’s family. Option D: Assessing the patient right before surgery is critical to making sure that all required prep was completed. Serving as a patient advocate and safety monitor, the circulating nurse observes the surgery and ensures that no aspect of patient care is missed.

Answer 15

Correct Answer: C. Return shortly to the patient’s room and remain there until the patient takes the medication The nurse should return shortly to the patient’s room and remain there until the patient takes the medication to verify that it was taken as directed. With the growing reliance on medication therapy as the primary intervention for most illnesses, patients receiving medication interventions are exposed to potential harm as well as benefits. Benefits are effective management of the illness/disease, slowed progression of the disease, and improved patient outcomes with few if any errors. Harm from medications can arise from unintended consequences as well as medication error (wrong medication, wrong time, wrong dose, etc.). Option A: The nurse should never leave medication at the patient’s bedside unless specifically requested to do so. Option B: With inadequate nursing education about patient safety and quality, excessive workloads, staffing inadequacies, fatigue, illegible provider handwriting, flawed dispensing systems, and problems with the labeling of drugs, nurses are continually challenged to ensure that their patients receive the right medication at the right time. Option D: Examples of errors that can be initiated at the transcribing, dispensing, and delivering stages include failure to transcribe the order, incorrectly filling the order, and failure to deliver the correct medication for the correct patient.

Answer 16

Correct Answer: C. ¾ ml The nurse solves the problem as follows: 10,000 units/7,500 units = 1 ml/X 10,000 X = 7,500 X= 7,500/10,000 or ¾ ml Option A: There are 3 primary methods for the calculation of medication dosages, as referenced above. These include Desired Over Have Method or Formula, Dimensional Analysis and Ratio and Proportion. Option B: Desired over Have or Formula Method is a formula or equation to solve for an unknown quantity (x) much like ratio proportion. Drug calculations require the use of conversion factors, such as when converting from pounds to kilograms or liters to milliliters. Simplistic in design, this method allows us to work with various units of measurement, converting factors to find our answer. Useful in checking the accuracy of the other methods of calculation as above mentioned, thus acting as a double or triple check. Option D: The Ratio and Proportion Method has been around for years and is one of the oldest methods utilized in drug calculations (as cited in Boyer, 2002)[Lindow, 2004]. Addition principals is a problem-solving technique that has no bearing on this relationship, only multiplication, and division are used to navigate through a ratio and proportion problem, not adding.

Answer 17

Correct Answer: C. 38.9 degrees C ``` To convert Fahrenheit degrees to centigrade, use this formula: C degrees = (F degrees – 32) x 5/9 C degrees = (102 – 32) 5/9 + 70 x 5/9 38.9 degrees C ``` Option A: Fahrenheit and Celsius both use different temperatures for the freezing and boiling points of water, and also use differently sized degrees. Water freezes at 0 degrees Celsius, and boils at 100 degrees C, while in Fahrenheit, water freezes at 32 degrees F and boils at 212 degrees F. Option B: Use the relationship in degree size to convert between Celsius and Fahrenheit. Because Celsius degrees are larger than those in Fahrenheit, to convert from Celsius to Fahrenheit, multiply the Celsius temperature by 1.8, then add 32. Option D: The Fahrenheit and Celsius scales are the two most common temperature scales. However, the two scales use different measurements for the freezing and boiling points of water, and also use different sized degrees.

Answer 18

Correct Answer: D. Arterial blood gas (ABG) analysis All of these tests help evaluate a patient with respiratory problems. However, ABG analysis is the only test that evaluates gas exchange in the lungs, providing information about a patient’s oxygenation status. An acceptable normal range of ABG values of ABG components are the following,[5][6] noting that the range of normal values may vary among laboratories, and in different age groups from neonates to geriatrics: pH (7.35-7.45) PaO2 (75-100 mmHg) PaCO2 (35-45 mmHg). Option A: A red blood cell count is a blood test that the doctor uses to find out how many red blood cells (RBCs) a person has. It’s also known as an erythrocyte count. The test is important because RBCs contain hemoglobin, which carries oxygen to the body’s tissues. The number of RBCs one has can affect how much oxygen the tissues receive. The tissues need oxygen to function. Option B: A sputum culture is a test that checks for bacteria or another type of organism that may be causing an infection in the lungs or the airways leading to the lungs. Sputum, also known as phlegm, is a thick type of mucus made in the lungs. Option C: The normal range for hemoglobin is: For men, 13.5 to 17.5 grams per deciliter. For women, 12.0 to 15.5 grams per deciliter.

Answer 19

Correct Answer: B. The diaphragm detects high-pitched sounds best. The diaphragm of a stethoscope detects high-pitched sound best; the bell detects low pitched sounds best. Palpation detects thrills best. The bell is flat and round and is covered by a thin layer of plastic known as the diaphragm. The diaphragm vibrates as sound is produced within the body. These vibrations travel from the bell, up the hollow tube which splits into two, and into hollow earpieces to be heard as sound by the medical professional. Option A: The smaller or other part of the resonator is called a bell. It is made up of hollow pieces of metal that help at picking up low-frequency sounds. Option C: Whenever a medical practitioner places a stethoscope diaphragm on a chest of a patient, vibration will occur at the flat surface of the stethoscope which is a result of sound waves that is being generated from the patient’s body. The vibration picked by the diaphragm is being protected externally in other to prevent sound loss and thereby channeled through the tube to a specific direction. Option D: The diaphragm is the lower part of the chest piece. It is a flat metallic disc surrounded by chill rings which enable it to pick a very high pitch sound.

Answer 20

Correct Answer: C. Within 6 months In most cases, an outpatient must fill a prescription for a controlled substance within 6 months of the date on which the prescription was written. A common reason people seek the care of medical professionals is pain relief. While many categories of pain medications are available, opioid analgesics are FDA-approved for moderate to severe pain. As such, they are a common choice for patients with acute, cancer-related, neurologic, and end-of-life pain. The prescribing of opioid analgesics for chronic pain is controversial and fraught with inconclusive standards. Option A: All health professionals engaged in pain management need an understanding of the treatment recommendations and safety concerns in prescribing opioid analgesics. Appropriate opioid prescribing requires a thorough patient assessment, short and long-term treatment planning, close follow-up, and continued monitoring. Option B: All providers need to be aware of not only appropriate patient assessment and treatment planning but also the possibility of use disorder, diversion, and potentially dangerous behavioral responses to controlled substances, e.g., opioid analgesics differ from pseudo-addiction and physical dependence. Option D: All providers should be familiar with the guidelines and laws for each schedule, which have, as their basis, the purpose of the drug and the risk of use disorder. In the United States, controlled substances are under strict regulation by both federal and state laws that guide their manufacture and distribution. Controlled substances have a high risk of resulting in an addiction and substance use disorder.

Answer 21

Correct Answer: D. The patient’s cognitive abilities The nurse must consider the patient’s cognitive abilities to understand drug instructions. If not, the nurse must find a family member or significant other to take on the responsibility of administering medications in the home setting. The patient’s ability to recover, occupational hazards, and socioeconomic status do not affect drug administration. Option A: Many drugs can be administered orally as liquids, capsules, tablets, or chewable tablets. Because the oral route is the most convenient and usually the safest and least expensive, it is the one most often used. However, it has limitations because of the way a drug typically moves through the digestive tract. Option B: For drugs administered orally, absorption may begin in the mouth and stomach. However, most drugs are usually absorbed from the small intestine. The drug passes through the intestinal wall and travels to the liver before being transported via the bloodstream to its target site. The intestinal wall and liver chemically alter (metabolize) many drugs, decreasing the amount of drug reaching the bloodstream. Consequently, these drugs are often given in smaller doses when injected intravenously to produce the same effect. Option C: When a drug is taken orally, food and other drugs in the digestive tract may affect how much of and how fast the drug is absorbed. Thus, some drugs should be taken on an empty stomach, others should be taken with food, others should not be taken with certain other drugs, and still others cannot be taken orally at all.

Answer 22

Correct Answer: A. Primary prevention Primary prevention precedes disease and applies to healthy patients. Primary prevention includes those preventive measures that come before the onset of illness or injury and before the disease process begins. Examples include immunization and taking regular exercise to prevent health problems from developing in the future. Option B: Secondary prevention focuses on patients who have health problems and are at risk for developing complications. Secondary prevention includes those preventive measures that lead to early diagnosis and prompt treatment of a disease, illness, or injury. This should limit disability, impairment or dependency and prevent more severe health problems from developing in the future. Option C: Tertiary prevention enables patients to gain health from others’ activities without doing anything themselves. Tertiary prevention includes those preventive measures aimed at rehabilitation following a significant illness. At this level, health educators work to retrain, re-educate and rehabilitate the individual who has already had an impairment or disability. Option D: Prevention, as it relates to health, is really about avoiding disease before it starts. It has been defined as the plans for, and the measures taken, to prevent the onset of a disease or other health problem before the occurrence of the undesirable health event.

Answer 23

Correct Answer: A. Leaves the bed in the high position when finished. When making a surgical bed, the nurse leaves the bed in a high position when finished. After placing the top linens on the bed without pouching them, the nurse fan folds these linens to the side opposite from where the patient will enter and places the pillow on the bedside chair. All these actions promote transfer of the postoperative patient from the stretcher to the bed. Option B: When making an occupied bed or unoccupied bed, the nurse places the pillow at the head of the bed and tucks the top sheet and blanket under the bottom of the bed. Option C: When making an occupied bed, the nurse rolls the patient to the far side of the bed. Bed Making is a key nursing skill that is essential for the promotion of patient comfort, hygiene, and wellbeing. Bed Making requires technical and practical skills and consideration should be given to issues of safety, moving and handling and infection control practices. Option D: The blanket is placed at the center of the bed with its top 20cms approximately from the top of the mattress. The top sheet is folded back over the blanket. The blanket is folded under the foot of the mattress. Make a square corner & tuck in along sides.

Answer 24

Correct Answer: C. ½ ml The nurse should give ½ ml of the drug. The dosage is calculated as follows: 250 mg/X=500 mg/1 ml 500x=250 X=1/2 ml Option A: There are 3 primary methods for the calculation of medication dosages, as referenced above. These include Desired Over Have Method or Formula, Dimensional Analysis and Ratio and Proportion Option B: Desired over Have or Formula Method is a formula or equation to solve for an unknown quantity (x) much like ratio proportion. Drug calculations require the use of conversion factors, such as when converting from pounds to kilograms or liters to milliliters. Simplistic in design, this method allows us to work with various units of measurement, converting factors to find our answer. Useful in checking the accuracy of the other methods of calculation as above mentioned, thus acting as a double or triple check. Option D: The Ratio and Proportion Method has been around for years and is one of the oldest methods utilized in drug calculations (as cited in Boyer, 2002)[Lindow, 2004]. Addition principals is a problem-solving technique that has no bearing on this relationship, only multiplication, and division are used to navigate through a ratio and proportion problem, not adding.

Answer 25

Correct Answer: C. Potential for drug dependence Patients can become dependent on barbiturates, especially with prolonged use. Due to the abuse potential of barbiturates, restricted access started with the passage of the Federal Comprehensive Drug Abuse and Control Act of 1970. Barbiturates classify as Schedule II-IV based on their abuse potential. Option A: Because of the rapid distribution of some barbiturates, no correlation exists between duration of action and half-life. The elimination half-life for thiopental is about 5 hours. In children, a shorter elimination half-time occurs due to greater hepatic clearance. Option B: Barbiturates are absorbed well. Age-related changes have been demonstrated in pharmacokinetics due to slower intercompartmental clearance in the elderly, resulting in higher serum concentrations with smaller drug doses. Option D: They do not cause hepatotoxicity, although existing hepatic damage does require cautious use of the drug because barbiturates are metabolized in the liver.

Answer 26

Correct Answer: A. Elevating the head of the bed. Elevating the head of the bed during enteral feeding minimizes the risk of aspiration and allows the formula to flow in the patient’s intestines. Lying prone/supine during feeding increases the risk of aspiration and therefore where clinically possible the client should be placed in an upright position. If unable to sit up for a bolus feed or if receiving continuous feeding, the head of the bed should be elevated 30-45 degrees during feeding and for at least 30 minutes after the feed to reduce the risk of aspiration. Option B: When such elevation is contraindicated, the patient should be positioned on the right side. Turn the patient onto their side. This will allow the tip of the tube to move to a position where fluid has accumulated. Option C: The nurse should give enteral feeding at room temperature to minimize GI distress. Continuous feeds should NOT be warmed. They may be removed from the fridge 15-20 minutes prior to administration to bring it to room temperature. Feeds should NOT be warmed in a microwave or in jugs of boiling water. Option D: To limit microbial growth, the nurse should hang only the amount of formula that can be infused in 3 hours. It should not hang for longer than 4 hours – use the dose limit function on the feed pump to ensure this occurs.

Answer 27

Correct Answer: C. Floor of the mouth The nurse should instruct the patient to touch the tip of the tongue to the roof of the mouth and then place the sublingual tablet on the floor of the mouth. Sublingual medications are absorbed directly into the bloodstream from the oral mucosa, bypassing the GI and hepatic systems. No drug is administered on top of the tongue or on the roof of the mouth. Option A: The cheek and area under the tongue have many capillaries, or tiny blood vessels. There, drugs can be absorbed directly into the bloodstream without going through the digestive system. Option B: These drugs do not go through the digestive system, so they aren’t metabolized through the liver. This means the client may be able to take a lower dose and still get the same results. Option D: With the buccal route, the tablet is placed between the gum and the cheek. Drugs that are absorbed under the tongue or between the cheek and gum can be easier to take for people who have problems swallowing pills.

Answer 28

Correct Answer: A. Cleaning from the center outward in a circular motion. The nurse always should clean around a wound drain, moving from center outward in ever-larger circles, because the skin near the drain site is more contaminated than the site itself. A Jackson-Pratt (JP) drain is used to remove fluids that build up in an area of the body after surgery. The JP drain is a bulb-shaped device connected to a tube. One end of the tube is placed inside the client during surgery. The other end comes out through a small cut in the skin. The bulb is connected to this end. The client may have a stitch to hold the tube in place. Option B: The nurse should never remove the drain before cleaning the skin. The JP drain removes fluids by creating suction in the tube. The bulb is squeezed flat and connected to the tube that sticks out of the body. The bulb expands as it fills with fluid. Option C: Alcohol should never be used to clean around a drain; it may irritate the skin and has no lasting effect on bacteria because it evaporates. Use soap and water or saline (salt water) solution to clean a JP drain site. Dip a cotton swab or gauze pad in the solution and gently clean the skin. Option D: The nurse should wear sterile gloves to prevent contamination, but a mask is not necessary. Wash hands with soap and water after discarding the gloves.

Answer 29

Correct Answer: C. 32 drop per minute ``` Giving 1,000 ml over 8 hours is the same as giving 125 ml over 1 hour (60 minutes) to find the number of milliliters per minute: 125/60 min = X/1 minute 60X = 125X = 2.1 ml/minute To find the number of drops/minute: 2.1 ml/X gtts = 1 ml/15 gtts X = 32 gtts/minute, or 32 drops/minute ``` Option A: When the nurse has an order for an IV infusion, it is her to make sure the fluid will infuse at the prescribed rate. IV fluids may be infused by gravity using a manual roller clamp or dial-a-flow, or infused using an infusion pump. Regardless of the method, it is important to know how to calculate the correct IV flow rate. Option B: When calculating the flow rate, determine which IV tubing will be used, microdrip or macrodrip, so the nurse can use the proper drop factor in her calculations. The drop factor is the number of drops in one mL of solution, and is printed on the IV tubing package. Macrodrip and microdrip refers to the diameter of the needle where the drop enters the drip chamber. Macrodrip tubing delivers 10 to 20 gtts/mL and is used to infuse large volumes or to infuse fluids quickly. Microdrip tubing delivers 60 gtts/mL and is used for small or very precise amounts of fluid, as with neonates or pediatric patients. Option D: To calculate the drops per minute, the drop factor is needed. The formula for calculating the IV flow rate (drip rate) is total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.

Answer 30

Correct Answer: A. Restlessness Early in shock, hyperactivity of the sympathetic nervous system causes increased epinephrine secretion, which typically makes the patient restless, anxious, nervous, and irritable. It also decreases tissue perfusion to the skin, causing pale, cool clammy skin. Shock is characterized by decreased oxygen delivery and/or increased oxygen consumption or inadequate oxygen utilization leading to cellular and tissue hypoxia. It is a life-threatening condition of circulatory failure and most commonly manifested as hypotension (systolic blood pressure less than 90 mm Hg or MAP less than 65 mmHg). Option B: Hypoxia at the cellular level causes a series of physiologic and biochemical changes, resulting in acidosis and a decrease in regional blood flow, which further worsens the tissue hypoxia. Option C: An above-normal heart rate is a late sign of shock. The most common clinical features/labs which are suggestive of shock include hypotension, tachycardia, tachypnea, obtundation or abnormal mental status, cold, clammy extremities, mottled skin, oliguria, metabolic acidosis, and hyperlactatemia. Option D: A urine output of 30 ml/hour is within normal limits. During this stage, most of the classic signs and symptoms of shock appear due to early organ dysfunction, resulting from the progression of the pre-shock stage as the compensatory mechanisms become insufficient.

Answer 31

Correct Answer: D. Carotid During a rapid assessment, the nurse’s first priority is to check the patient’s vital functions by assessing his airway, breathing, and circulation. To check a patient’s circulation, the nurse must assess his heart and vascular network function. This is done by checking his skin color, temperature, mental status and, most importantly, his pulse. The nurse should use the carotid artery to check a patient’s circulation. Option A: In a patient with circulatory problems or a history of compromised circulation, the radial pulse may not be palpable. Examiners frequently evaluate the radial artery during a routine examination of adults, due to the unobtrusive position required to palpate it and its easy accessibility in various types of clothing. Like other distal peripheral pulses (such as those in the feet) it also may be quicker to show signs of pathology. Option B: The brachial pulse is palpated during rapid assessment of an infant. The brachial artery is often the site of evaluation during cardiopulmonary resuscitation of infants. It is palpated proximal to the elbow between the medial epicondyle of the humerus and the distal biceps tendon. Option C: The femoral pulse may be the most sensitive in assessing for septic shock and is routinely checked during resuscitation. It is palpated distally to the inguinal ligament at a point less than halfway from the pubis to the anterior superior iliac spine.

Answer 32

Correct Answer: A. Constipation Habitually ignoring the urge to defecate can lead to constipation through loss of the natural urge and the accumulation of feces. Functional constipation is a prevalent condition in childhood, about 29.6% worldwide. In the United States, it represents 3% to 5% of pediatric visits and a considerable annual health care cost. Most children do not have an etiological factor, and one third continue to have problems beyond adolescence. Option B: Diarrhea will not result-if anything, there is increased opportunity for water reabsorption because the stool remains in the colon, leading to firmer stool. Diarrhea is described as three or more loose or watery stools a day. Infection commonly causes acute diarrhea. Noninfectious etiologies are more common as the duration of diarrhea becomes chronic. Treatment and management are based on the duration and specific etiology. Option C: Ignoring the urge shows a strong voluntary sphincter, not a weak one that could result in incontinence. Fecal incontinence (FI) is the involuntary passage of fecal matter through anus or inability to control the discharge of bowel contents. Its severity can range from an involuntary passage of flatus to complete evacuation of fecal matter. Depending on the severity of the disease, it has a significant impact on a patient’s quality of life Option D: Hemorrhoids would only occur only if severe drying out of the stool occurs, and thus repeated need to strain to pass stool. Hemorrhoids are rich in vascular supply and have a tendency to engorge and prolapse. Symptoms can vary from mild itching, bleeding to severe pain. Unfortunately, because of the location, many patients never seek treatment for fear of embarrassment.

Answer 33

Correct Answer: B. “I need to take a laxative such as milk of magnesium or if I don’t have a BM every day” Stimulant laxatives can be very irritating and are not the preferred treatment for occasional constipation in older adults. In addition, a normal stool pattern for an older adult may not be daily elimination. The cause of constipation is multifactorial. The problem may arise in the colon or rectum or it may be due to an external cause. In most people, slow colonic motility that occurs after years of laxative abuse is the problem. In a few patients, the cause may be related to an outlet obstruction like rectal prolapse or a rectocele. External causes of constipation may include poor dietary habits, lack of fluid intake, overuse of certain medications, an endocrine problem like hypothyroidism or some type of an emotional issue. Option A: The standard of practice in assisting the older adults to maintain normal function of the gastrointestinal tract is regular ingestion of a well-balanced diet, adequate fluid intake, and regular exercise. Option C: If the bowel pattern is not regular with these activities, this abnormality should be reported. Pathophysiology underlying functional constipation is multifactorial and not well understood. Factors that may contribute to functional constipation include pain, fever, dehydration, dietary and fluid intake, psychological issues, toilet training, medicines, and family history of constipation. Option D: A normal fiber intake, fluid intake, and physical activity level are recommended, and the routine use of prebiotics or probiotics is not recommended in the treatment of childhood constipation.

Answer 34

Correct Answer: D. Low, small volume Small volume enemas along with other preparations are used to prepare the client for this procedure. The small volume enema is used to clean the lower portion of the colon or the sigmoid. This type of cleansing enema is often used for the patient who is constipated but does not need cleansing of the higher colon. The amount used is less than 500 ml and the bag is raised no higher than 12 inches. Option A: An oil retention enema is used to soften hard stool. A rectal injection of mineral oil or vegetable Oil, introduced at low pressure and retained for 30 minutes to 3 hours before being expelled. given to soften feces in cases of constipation or impaction. The volume of oil is relatively low, four to six ounces are commonly used, which allows the oil to be more easily retained. Option B: Return flow enemas help expel flatus because of the risk of loss of fluid and electrolytes A return-flow enema, or Harris flush, is used to remove intestinal gas and stimulate peristalsis. A large volume fluid is used but the fluid is instilled in 100-200 ml increments. Then, the fluid is drawn out by lowering the container below the level of the bowel. This brings the flatus out with the fluid. Option C: High, large volume enemas are seldom used. The purpose of a large volume enema is to clean as much of the colon as possible of feces, as an intervention for constipation as well as “bowel prep” before a diagnostic procedure. The amount used is 500-1000 ml and the bag is raised as high as 18 inches above the anal opening. The patient is instructed to retain and hold the fluid as long as possible to induce peristalsis and cause evacuation of feces.

Answer 35

Correct Answer: C. The stoma color is a deep red purple. An established stoma should be dark pink like the color of the buccal mucosa and is slightly raised above the abdomen. A stoma is the exteriorization of a loop of bowel from the anterior abdominal wall, done during a surgical procedure. It is done for diversion or decompression of the remaining bowel. It may be temporary or permanent, depending on the indication for which it was performed. Most stomas are incontinent, which means that there is no voluntary control over the passage of flatus and feces from the stoma. Option A: The stoma should be assessed and must be moist, above skin level, and pink to red in color, and the peristomal skin should be normal. Any deviation from this should be notified to the surgeon. The stoma should be measured, or the previous measurement remembered and size should not be more than 1/16-1/8. Option B: The skin under the appliance may remain pink/red for a while after the adhesive is pulled off. The peristomal skin should be dried appropriately to allow good seal formation. Adhesive pastes or powders may also be applied peristomally. The paper cover on the back of the flange is then removed with the border tape in place. It is then placed around the stoma and held in place for 1 to 2 minutes to create an adequate seal. Option D: Feces from an ascending ostomy are very liquid, less so from a transverse ostomy, and more solid from a descending or sigmoid stoma. Colostomy diarrhea may be complained by the patient in case of ascending or transverse colostomies in case they are not fully explained about the nature of content expected, but stomal diarrhea may be the result of extensive resection with failure of bowel adaptation or if associated with short bowel syndrome.

Answer 36

Correct Answer: B. The client will return to his or her previous fecal elimination pattern. Once the cause of diarrhea has been identified and corrected, the client returns to his or her previous elimination pattern. Diarrhea is a common adverse effect of antibiotic treatments. Antibiotic-associated diarrhea occurs in about 5-30% of patients either early during antibiotic therapy or up to two months after the end of the treatment. The frequency of antibiotic-associated diarrhea depends on the definition of diarrhea, the inciting antimicrobial agents, and host factors. Option A: This is not an example of an allergy to the antibiotic but a common consequence of overgrowth of bowel organisms not killed by the drug. Antibiotic-associated diarrhea results from disruption of the normal microflora of the gut by antibiotics. This microflora, composed of 1011 bacteria per gram of intestinal content, forms a stable ecosystem that permits the elimination of exogenous organisms. Antibiotics disturb the composition and the function of this flora and enable the overgrowth of micro-organisms that induce diarrhea. Option C: Antidiarrheal medications are usually prescribed according to the number of stools, not routinely around the clock. Managing diarrhea depends on the clinical presentation and the inciting agent. In mild to moderate diarrhea conventional measures include rehydration or discontinuation of the inciting agent or its replacement by an antibiotic with a lower risk of inducing diarrhea, such as quinolones, co-trimoxazole, or aminoglycosides. In 22% of cases of diarrhea related to C difficile, withdrawal of the inciting agent will lead to resolution of clinical signs in three days. Option D: Increasing intake of soluble fiber such as oatmeal or potatoes may help absorb excess liquid and decrease diarrhea, but insoluble fiber will not. The key measure for preventing antibiotic-associated diarrhea, however, is to limit antibiotic use. Probiotics have proved useful in preventing diarrhea, but the number of clinical trials is limited, and further controlled trials using different probiotics are needed

Answer 37

Correct Answer: B. After assessing the stoma and surrounding skin, notify the surgeon. The client has assessment findings consistent with complications of surgery. Providers and nurses should monitor stomas at regular intervals to look for the multiple complications of colostomies as an integrated team approach. Some complications are extremely troublesome to patients, and they come to the hospital with these presentations, but others may be more occult and have to be looked for. Option A: Irrigating the stoma is a dependent nursing action, and is also intervention without appropriate assessment. Some procedures like irrigation or enema should be avoided in case of stoma prolapse, chemotherapy, pelvic or abdominal radiation treatments, diarrhea-producing medication, or in case of an irregular functioning stoma and may lead to dependence. Option C: Assessing the peristomal skin area is an independent action, but administering an antiemetic is an intervention without appropriate assessment. Antiemetics are generally ordered to treat immediate postoperative nausea, not several days postoperative. Option D: Administering a bulk-forming laxative to a nauseated postoperative client is contraindicated. The surgeon must call the patient for regular follow up to assess the condition of the stoma and look for any complications and also assess the disease process for which the colostomy was made and also plan for colostomy closure in case of temporary colostomies.

Answer 38

Correct Answer: C. Return flow This provides relief of postoperative flatus, stimulating bowel motility. Options one, two, and four manage constipation and do not provide flatus relief. A return-flow enema, or Harris flush, is used to remove intestinal gas and stimulate peristalsis. A large volume fluid is used but the fluid is instilled in 100-200 ml increments. Then, the fluid is drawn out by lowering the container below the level of the bowel. This brings the flatus out with the fluid. Option A: The soapsuds enema uses a mixture of a mild soap and warm water injected into the colon in order to stimulate a bowel movement. Normally given to relieve constipation or for bowel cleansing before a medical examination or procedure. Option B: An enema that may be used to provide nourishment, medication, or anesthetic. It should be made from fluids that will not stimulate peristalsis. A small amount of solution (e.g., 100 to 250 mL) is typically used in adults. Option D: If fecal material is hardened, an oil-retention enema may be given to soften the feces. Commercially packaged enemas contain 90-120 ml solution. The patient should retain the solution to at least one hour for the enema to be effective. This enema is usually followed by a cleansing enema.

Answer 39

Correct Answer: C. Semi soft tar colored stools Blood in the upper GI tract is black and tarry. Gastrointestinal (GI) bleeding is a symptom of a disorder in the digestive tract. The blood often appears in stool or vomit but isn’t always visible, though it may cause the stool to look black or tarry. The level of bleeding can range from mild to severe and can be life-threatening. Option A: This can be a sign of malabsorption in an infant. Malabsorption syndromes encompass numerous clinical entities that result in chronic diarrhea, abdominal distention, and failure to thrive. Clinical malabsorption can be broken down into several distinct conditions, both congenital and acquired, that affect one or more of the different steps in the intestinal hydrolysis and subsequent transport of nutrients. Option B: Brown, formed stool is a normal stool. Anywhere between a firm and soft consistency is pretty much normal. If it sways one way or another, it could suggest some digestion or fiber issues. Option D: Narrow, pencil-shaped stool is a characteristic of an obstructive condition of the rectum. Narrow stools that occur infrequently probably are harmless. However in some cases, narrow stools — especially if pencil thin — may be a sign of narrowing or obstruction of the colon due to colon cancer.

Answer 40

Correct Answer: A, C, D, and E Incontinence is the inability to control feces of normal consistency. Fecal incontinence (FI) is the involuntary passage of fecal matter through anus or inability to control the discharge of bowel contents. Its severity can range from an involuntary passage of flatus to complete evacuation of fecal matter. Depending on the severity of the disease, it has a significant impact on a patient’s quality of life Option A: This is the most appropriate. The client is unable to decide when stool evacuation will occur. Patients with fecal incontinence have an unintentional loss of liquid or solid stool. In true anal incontinence, there is loss of control of the anal sphincter which leads to the untimely release of feces. Option B: Risk for deficient fluid volume is more appropriate for a client with diarrhea. Avoid perianal skin soiling with regular cleaning, zinc oxide application, incontinence pads. Avoid food which can provoke diarrhea (high lactose/ fructose diet). Option C: The client’s thoughts about self may be altered if unable to control stool evacuation. To maintain fecal continence, there is a complex interplay of several organ systems and nerves. As the fecal mass presents to the rectum, this causes distension. The sensation of rectal distension is transmitted by the parasympathetic nerves (S2-S4), which induces relaxation of the rectoanal inhibitory reflex and contraction of the rectoanal contractile reflex. The rectal lining has a rich supply of nerve endings that can sample if the mass is liquid or solid. It is believed that abnormal sampling and lowered anorectal sensation most likely contribute to fecal incontinence in many individuals. Option D: The prognosis for most patients with fecal incontinence is guarded. Short term outcomes after sphincteroplasty vary from 30-60%. Satisfactory results are seen in less than 50% of patients in the long term. The quality of life is poor and mental anguish is common. Option E: Increased tissue contact with fecal material may result in impairment. Fecal incontinence is a complex issue that is not easy to manage. The vast number of methods used to manage the condition is an indication that no method works reliably. Patients with fecal incontinence have enormous mental anguish, depression, and anxiety.

Answer 41

Correct Answer: A. Has a spinal cord injury A fracture bedpan has a low back that promotes function of the patient’s lower back while on the bedpan. The fracture pan has one flat end for ease of use with specific patient populations: i.e. hip fractures, hip replacements, or lower extremity fractures. Using the toilet may be a source of discomfort and embarrassment among all genders. Semi-private rooms or shared wards and hospital overcrowding are a challenge regarding patient privacy. Option B: Bedpans come in regular size or a smaller, fracture pan. Bedpans are chosen based on diagnosis, patient comfort or preference and if any contraindications exist for using the regular size such as a fracture. The regular bedpan is larger than its fracture counterpart. Bariatric bedpans are available up to a 1200-pound (544-kg) capacity. Option C: A patient that can assist with care by raising their hips is approached differently than a patient that cannot lift their hips due to surgical considerations, fractures, or other contraindications. In both cases, ensure the patient is pulled up as high as they can be on the stretcher or bed. If they can assist with raising their hips, then raise the head of the bed at least thirty degrees. Option D: Positioning in this Semi-Fowler’s position allows for anatomical support and facilitates ease of defecation or urination by assuming a natural position for these bodily functions. According to a 2003 study, body positioning has a significant influence on intestinal gas propulsion and transit times with gastric flow being faster in the upright position than when supine [Dainese, Serra, Azpiroz & Malagelada, 2003].

Answer 42

Correct Answer: D. Kale Kale is an excellent source of dietary fiber. A serving of 3 1/2 ounces of kale contains 6.6 g of dietary fiber. Fiber is a very important component of our diet and comes from plant-based food sources (fruits, vegetables, legumes and whole grains). Different food sources contain different types of fiber and resistant starches and the side effects depend on the individual’s microbiome (gut bacteria). Instead of avoiding fiber altogether, you may want to identify the certain types of food that cause the distress. Option A: One slice of whole wheat bread contains only 1.5 g of dietary fiber. Whole wheat bread is made from flour that contains the entire wheat kernel, including the bran and germ. It’s here that wheat packs the most nutrients, such as fiber, B vitamins, iron, folate, potassium, and magnesium. Leaving the wheat kernel intact makes for a less processed, more nutritious bread. Option B: A serving of a 1/2 cup of white rice contains only 0.8 g of dietary fiber. White rice is mostly a source of “empty” calories and carbs with very few essential nutrients. 100 grams (3.5 ounces) of cooked brown rice provide 1.8 grams of fiber, whereas 100 grams of white provide only 0.4 grams of fiber (1, 2). Bottom Line: Brown rice is much higher in nutrients than white rice. Option C: A serving of 3 1/2 ounces of cooked pasta contains only 1.6 g of dietary fiber. Whole-wheat pasta is usually made from whole-wheat durum semolina, or flour made from the whole grain rather than the striped grain. For about 175 calories, a 1-cup serving of cooked whole-wheat spaghetti delivers 6.3 grams of fiber, or 25 percent of the daily value.

Answer 43

Correct Answer: C. “I’m going to have to irrigate my stoma so I have a bowel movement every morning” This statement is inaccurate in relation to an ileostomy and indicates that the patient needs more teaching. An ileostomy produces liquid fecal drainage that is constant and cannot be regulated. An ileostomy is when the lumen of the ileum (small bowel) is brought through the abdominal wall via a surgical opening (created by an operation). This can either be temporary or permanent, an end or a loop. The purpose of an ileostomy is to evacuate stool from the body via the ileum rather than the usual route of the anus. Option A: The odor from drainage is minimal because fewer bacteria are present in the ileum compared with the large intestine. There are different indications for forming an ileostomy but essentially arrive at the same result of diverting stool out of the body without it ever entering the colon. Option B: An ileostomy is an opening into the ileum (distal small intestine from the jejunum to the cecum). Cleansing the skin, skin barriers, and a well fitted appliance are precautions to protect the skin around the ileostomy stoma. The drainage from ileostomy contains enzymes that can damage the skin. Option D: An ileostomy stoma does not have a sphincter that can control the flow of flatus or drainage, resulting in noise. The output from an ileostomy consists of loose or porridge-like stool consistent with that expected to pass through the small bowel (as it is the large bowel that is responsible for making the stool more solid dependent upon water absorption). The output from an ileostomy can vary but typically ranges from 200 to 700 ml per day, and an Ileostomy is typically formed on the right side of the abdomen.

Answer 44

Correct Answer: D. Lower the solution container after instilling about 150 mL of solution. Lowering the container of solution creates a siphon effect that pulls the instilled fluid back out through the rectal tube into the solution container. The return flow promotes the evacuation of gas from the intestines. This technique is used only with a return flow enema. This action is appropriate for all types of enemas. Option A: All rectal tubes should be lubricated to facilitate entry of the tube into the anus and rectum and prevent mucosal trauma. Use a solution at a temperature of 105o to 110oF in adults and 100oF in children. Cool solutions will increase the incidence of cramping. Option B: The anal canal is 1 to 2 inches long. Inserting the rectal tube 3 to 4 inches ensures that the tip of the tube is beyond the anal sphincter. The recommended position for the patient during enema administration is lying in the left lateral position with their right leg flexed as much as possible. Option C: The solution container should be raised no higher than 12 inches for all enemas; this allows the solution to instill slowly, which limits discomfort and intestinal spasms. Alternately, raise the enema container 12-18 inches above the rectum for an adult and administer approximately 200 ml of fluid, then lower the container 12-18 inches below the patient’s rectum until no further flatus is seen

Answer 45

Correct Answer: B. Dysrhythmias Straining on defecation requires the person to hold the breath while bearing down. This maneuver increases the intrathoracic and intracranial pressures, which can precipitate dysrhythmias, brain attack, and respiratory difficulties; all of these can be life threatening. Strain at stool causes blood pressure rise, which can trigger cardiovascular events such as congestive heart failure, arrhythmia, acute coronary disease, and aortic dissection. Option A: The loss of the voluntary ability to control the passage of fecal or gaseous discharges through the anus is caused by impaired functioning of the anal sphincter or its nerve supply, not straining on defecation. Fecal incontinence is the inability to control bowel movements, causing stool (feces) to leak unexpectedly from the rectum. Also called bowel incontinence, fecal incontinence ranges from an occasional leakage of stool while passing gas to a complete loss of bowel control. Option C: Fecal impaction is caused by prolonged retention and the accumulation of fecal material in the large intestine, not straining on defecation. Fecal impaction is a severe bowel condition in which a hard, dry mass of stool becomes stuck in the colon or rectum. This immobile mass will block the passage and cause a buildup of waste, which a person will be unable to pass. Option D: Although straining on defecation can contribute to the formation of hemorrhoids, this is not the primary reason straining on defecation is discouraged. Hemorrhoids, although painful, are not life-threatening. Hemorrhoids are rich in vascular supply and have a tendency to engorge and prolapse. Symptoms can vary from mild itching, bleeding to severe pain. Unfortunately, because of the location, many patients never seek treatment for fear of embarrassment.

Answer 46

Correct Answer: D. The specimen cannot be contaminated with urine. For fecal occult blood testing at home, the stool specimens cannot be contaminated with water or urine. The fecal occult blood test (FOBT) is a diagnostic test to assess for occult blood in the stool. This test has commonly been used for colorectal cancer screening, especially in developed nations. When used correctly for screening, this testing modality has established associations with decreased morbidity and mortality. When performing at home, the stool should be collected in a dry, clean container. Option A: Some proteins such as red meat, fish, and poultry can alter the test results. Three days prior to fecal occult blood testing, avoidance of certain foods should be to help prevent false test results. False-positive results have been associated with red or rare meat as well as raw fruits and vegetables, including but not limited to horseradish, raw turnips, cantaloupe, broccoli, cauliflower, parsnips, and red radishes. False-negative results are also known to occur in patients taking ascorbic acid (vitamin C) in excess of 250mg/day. Option B: Three specimens from three different bowel movements are required. One problem with FOBT is the need for medication and dietary restrictions before testing. These restrictions are in order to decrease the risk of false negative and false-positive results. Many studies assessing the risk of these false results exist. One particular retrospective study evaluated the medications that could create false-positive results and encouraged patients to avoid these medications, if possible, for seven days before testing. The listed medications include acetylsalicylic acid, unfractionated or low-molecular-weight heparin, warfarin, clopidogrel, nonsteroidal anti-inflammatory drugs, and selective serotonin reuptake inhibitors. Option C: A blue color indicates blood in the stool. If the patient’s fecal occult blood test does not turn blue, it is negative. If the card turns blue, this is positive and requires further gastroenterological workup.

Answer 47

Correct Answer: B. Fresh food and whole-wheat toast. A high fiber diet promotes normal bowel elimination. The choice of fruit and toast is the highest-fiber option. Most Americans consume only half the levels of recommended fiber per day, which is almost 15 grams per day. All existing definitions recognize fiber as “carbohydrate or lignin which bypasses digestion in the small intestine and is partially or completely fermented in the large intestine or colon.” Option A: Macaroni and cheese is a low residue option that could actually worse and constipate. Insoluble fiber maintains bowel movements. They absorb water and soften the stool. Soft stool is easier to pass, thus preventing constipation. They also add bulk to the stools hence prevent the formation of loose stools. Option C: Rice pudding and ripe bananas are low residue options that could actually worsen constipation. High fiber diet prevents the formation or worsening of hemorrhoids, and of diverticular disease, which presents as outpouchings in the walls of the colon. Option D: Roast chicken and white rice or low residue options that could actually worsen constipation. They are water-soluble and derived from the inner flesh of plants such as pectin, gums, and mucilage. They form a viscous gel and are usually fermented by bacteria in the colon into gases and by-products such as short-chain fatty acids. They alter the blood glucose and cholesterol concentrations.

Answer 48

Correct Answer: B, C, and D Diarrhea is described as three or more loose or watery stools a day. Infection commonly causes acute diarrhea. Noninfectious etiologies are more common as the duration of diarrhea becomes chronic. Treatment and management are based on the duration and specific etiology. Rehydration therapy is an important aspect of the management of any patient with diarrhea. Prevention of infectious diarrhea includes proper handwashing to prevent the spread of infection. Option A: Prolonged diarrhea is more likely to cause tachycardia than bradycardia. Diarrhea is the result of reduced water absorption by the bowel or increased water secretion. A majority of acute diarrheal cases are due to infectious etiology. Chronic diarrhea is commonly categorized into three groups; watery, fatty (malabsorption), or infectious. Option B: Prolonged diarrhea leads to dehydration, which causes a decrease in blood pressure. In bacterial and viral diarrhea, the watery stool is the result of injury to the gut epithelium. Epithelial cells line the intestinal tract and facilitate the absorption of water, electrolytes, and other solutes. Infectious etiologies cause damage to the epithelial cells which leads to increased intestinal permeability. The damaged epithelial cells are unable to absorb water from the intestinal lumen leading to loose stool. Option C: Prolonged diarrhea leads to dehydration, which causes fever. History should include the duration of symptoms, accompanying symptoms, travel history, and exposures to medications and food. It is important to ask about the stool frequency, type, volume, and presence of blood or mucus. Patients with diarrhea may also complain of abdominal pain or cramping, vomit, bloating, flatulence, fever, and bloody or mucoid stools. Option D: Prolonged diarrhea is more likely to cause a fluid deficit. An important aspect of diarrhea management is replenishing fluid and electrolyte loss. Patients should be encouraged to drink diluted fruit juice, Pedialyte or Gatorade. In more severe cases of diarrhea, IV fluid rehydration may become necessary. Option E: Peripheral edema results from a fluid overload. Important aspects of the physical exam include the patient’s vital signs, volume status, and abdominal exam. Dry mucous membranes, poor skin turgor, and delayed capillary refill are signs of dehydration. A thorough history and physical exam are important to determine the proper diagnostic workup.

Answer 49

Correct Answer: A, B, and C Enemas are rectal injections of fluid intended to cleanse or stimulate the emptying of the bowel. Enemas can be administered by a medical professional or self-administered at home. Enemas may also be prescribed to flush out the colon before certain diagnostic tests or surgeries. The bowel needs to be empty before these procedures to reduce infection risk and prevent stool from getting in the way. Option A: The nurse should warm the enema solution because cold fluid can cause abdominal cramping and hot fluid can injure the intestinal mucosa. Cleansing enemas are water-based and meant to be held in the rectum for a short time to flush the colon. Once injected, they’re retained for a few minutes until the body rids itself of the fluid, along with loose matter and impacted stool in the bowel. Option B: Option B allows a downward flow of solution by gravity along the natural anatomical curve of the sigmoid colon. Some advocates claim that enemas can support weight loss, remove toxins and heavy metals from the body, and improve the skin, immunity, blood pressure, and energy levels. Option C: Lubrication prevents trauma or irritation to the rectal mucosa. The least irritating of all options, water or saline — salt water that mimics the body’s sodium concentration — are used primarily for their ability to expand the colon and mechanically promote defecation. Option D: This is an appropriate length of insertion for a child. For an adult client, the nurse should insert a tube 3 to 4 inches. Research shows that enemas used in preparation for medical procedures significantly disrupt gut bacteria, though the effect appears to be temporary. However, enemas that are split and administered in two doses seem to have fewer effects on the microbiome. Option E: The height of the fluid container affects the speed of installation. The maximum recommended height is 18 inches. Hanging the container higher than that could cause rapid installation and possibly painful distention of the colon

Answer 50

Correct Answer: D. Lower the enema fluid container. To relieve the client’s discomfort, the nurse should slow the rate of installation by reducing the height of the enema solution container. An enema may be helpful when there is a problem forming or passing stool. The colon, also called the large intestine or large bowel, is a long, hollow organ in the abdomen. It plays an important role in digestion by removing water from digested material and forming feces (stool). In some circumstances, due to diet, medical condition, or medication, among other possible causes, the bowel may form stool that is hard to pass easily resulting in constipation. Option A: Taking slow, deep breaths is more therapeutic for easing discomfort than holding the breath. A cleansing enema can also lower the amount of bacteria in your colon and reduce the risk of infection for certain surgeries. Option B: The nurse should stop the installation if the client’s abdomen becomes rigid and distended or if the nurse notes bleeding from the rectum. An enema should not be painful when administered properly. The client may feel fullness, mild pressure, or brief, minimal cramping during the procedure. The client may also feel like he needs to have a bowel movement. Option C: This intervention is not therapeutic as it implies that the client must tolerate the discomfort and that the nurse cannot or will not do anything to ease it. The client may take a few long, deep breaths to help himself relax. If he has pain or discomfort while self-inserting an enema, stop and contact the doctor

Answer 51

Correct Answer: D. Cyanosis A bluish tinge to mucous membranes is called cyanosis. This is most accurate because it is what the nurse observes. Cyanosis refers to a bluish cast to the skin and mucous membranes. Peripheral cyanosis is when there is a bluish discoloration to the hands or feet. It’s usually caused by low oxygen levels in the red blood cells or problems getting oxygenated blood to the body. Option A: The nurse can only observe signs/symptoms of hypoxia. More information is needed to validate this conclusion. Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body. Option B: Hypoxemia requires blood oxygenation saturation data to be confirmed. Hypoxemia refers to the low level of oxygen in the blood, and the more general term hypoxia is an abnormally low oxygen content in any tissue or organ or the body as a whole. Hypoxemia can cause hypoxia (hypoxemic hypoxia), but hypoxia can also occur via other mechanisms, such as anemia. Option C: Dyspnea is difficult to breathe. Dyspnea is the medical term for shortness of breath, sometimes described as “air hunger.” It is an uncomfortable feeling. Shortness of breath can range from mild and temporary to serious and long-lasting. It is sometimes difficult to diagnose and treat dyspnea because there can be many different causes.

Answer 52

Correct Answer: B. Administering measles, mumps, and rubella immunization to an infant. Immunizing an infant is an example of primary prevention, which aims to prevent health problems. Primary prevention includes those preventive measures that come before the onset of illness or injury and before the disease process begins. Examples include immunization and taking regular exercise to prevent health problems developing in the future. Option A: Administering digoxin to treat heart failure and obtaining a smear for a screening test are examples for secondary prevention, which promotes early detection and treatment of disease. Those preventive measures that lead to early diagnosis and prompt treatment of a disease, illness, or injury to prevent more severe problems developing. Here health educators such as Health Extension Practitioners can help individuals acquire the skills of detecting diseases in their early stages. Option C: Obtaining a Papanicolau smear is a secondary prevention. Secondary prevention includes those preventive measures that lead to early diagnosis and prompt treatment of a disease, illness, or injury. This should limit disability, impairment, or dependency and prevent more severe health problems developing in the future. Option D: Using occupational therapy to help a patient cope with arthritis is an example of tertiary prevention, which aims to help a patient deal with the residual consequences of a problem or to prevent the problem from recurring. Tertiary prevention includes those preventive measures aimed at rehabilitation following significant illness. At this level, health educators work to retrain, re-educate and rehabilitate the individual who has already had an impairment or disability.

Answer 53

Correct Answer: B. Inspection Inspection always comes first when performing a physical examination. It is important to begin with the general examination of the abdomen with the patient in a completely supine position. The presence of any of the following signs may indicate specific disorders. Percussion and palpation of the abdomen may affect bowel motility and therefore should follow auscultation. Option A: The last step of the abdominal examination is auscultation with a stethoscope. The diaphragm of the stethoscope should be placed on the right side of the umbilicus to listen to the bowel sounds, and their rate should be calculated after listening for at least two minutes. Normal bowel sounds are low-pitched and gurgling, and the rate is normally 2-5/min. Absent bowel sounds may indicate paralytic ileus and hyperactive rushes (borborygmi) are usually present in small bowel obstruction and sometimes may be auscultated in lactose intolerance. Option C: A proper technique of percussion is necessary to gain maximum information regarding the abdominal pathology. While percussing, it is important to appreciate tympany over air-filled structures such as the stomach and dullness to percussion which may be present due to an underlying mass or organomegaly (for example, hepatomegaly or splenomegaly). Option D: The ideal position for abdominal examination is to sit or kneel on the right side of the patient with the hand and forearm in the same horizontal plane as the patient’s abdomen. There are three stages of palpation that include the superficial or light palpation, deep palpation, and organ palpation and should be performed in the same order. Maneuvers specific to certain diseases are also a part of abdominal palpation.

Answer 54

Correct Answer: D. S1 is loudest at the apex, and S2 is loudest at the base. The S1 sound—the “lub” sound—is loudest at the apex of the heart. It sounds longer, lower, and louder there than the S2 sounds. The S2—the “dub” sound—is loudest at the base. It sounds shorter, sharper, higher, and louder there than S1. Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Vibrations of these structures from the blood flow create audible sounds — the more turbulent the blood flow, the more vibrations that get created. Option A: The S1 heart sound is produced as the mitral and tricuspid valves close in systole. This structural and hemodynamic change creates vibrations that are audible at the chest wall. The mitral valve closing is the louder component of S1. It also occurs sooner because of the left ventricle contracts earlier in systole. Option B: Changes in the intensity of S1 are more attributable to forces acting on the mitral valve. Such causes include a change in left ventricular contractility, mitral structure, or the PR interval. However, under normal resting conditions, the mitral and tricuspid sounds occur close enough together not to be discernible. The most common reasons for a split S1 are things that delay right ventricular contraction, like a right bundle branch block. Option C: The S2 heart sound is produced with the closing of the aortic and pulmonic valves in diastole. The aortic valve closes sooner than the pulmonic valve, and it is the louder component of S2; this occurs because the pressures in the aorta are higher than the pulmonary artery

Answer 55

Correct Answer: B. Nursing diagnosis The nurse identifies human responses to actual or potential health problems during the nursing diagnosis step of the nursing process. The formulation of a nursing diagnosis by employing clinical judgment assists in the planning and implementation of patient care. The North American Nursing Diagnosis Association (NANDA) provides nurses with an up to date list of nursing diagnoses. A nursing diagnosis, according to NANDA, is defined as a clinical judgment about responses to actual or potential health problems on the part of the patient, family or community. Option A: During the assessment step, the nurse systematically collects data about the patient or family. Assessment is the first step and involves critical thinking skills and data collection; subjective and objective. Subjective data involves verbal statements from the patient or caregiver. Objective data is measurable, tangible data such as vital signs, intake and output, and height and weight. Option C: During the planning step, the nurse develops strategies to resolve or decrease the patient’s problem. The planning stage is where goals and outcomes are formulated that directly impact patient care based on EDP guidelines. These patient-specific goals and the attainment of such assist in ensuring a positive outcome. Option D: During the evaluation step, the nurse determines the effectiveness of the plan of care. This final step of the nursing process is vital to a positive patient outcome. Whenever a healthcare provider intervenes or implements care, they must reassess or evaluate to ensure the desired outcome has been met. Reassessment may frequently be needed depending upon overall patient condition. The plan of care may be adapted based on new assessment data.

Answer 56

Correct Answer: B. Bananas and oranges Because furosemide is a potassium-wasting diuretic, the nurse should plan to teach the patient to increase intake of potassium-rich foods, such as bananas and oranges. Potassium is a mineral in the cells. It helps the nerves and muscles work as they should. The right balance of potassium also keeps the heart beating at a steady rate. Fresh, green vegetables; lean red meat; and creamed corn are not good sources of potassium. Option A: GLVs are considered as natural caches of nutrients for human beings as they are a rich source of vitamins, such as ascorbic acid, folic acid, tocopherols, ?-carotene, and riboflavin, as well as minerals such as iron, calcium, and phosphorous. Option C: Lean red meat is an excellent source of high biological value protein, vitamin B12, niacin, vitamin B6, iron, zinc, and phosphorus. It is a source of long?chain omega?3 polyunsaturated fats, riboflavin, pantothenic acid, selenium, and, possibly, also vitamin D. It is also relatively low in fat and sodium. Option D: Corn has several health benefits. Because of the high fiber content, it can aid with digestion. It also contains valuable B vitamins, which are important to your overall health. Corn also provides our bodies with essential minerals such as zinc, magnesium, copper, iron, and manganese.

Answer 57

Correct Answer: D. Bone marrow suppression The most toxic reaction to chloramphenicol is bone marrow suppression. Chloramphenicol is a synthetically manufactured broad-spectrum antibiotic. It was initially isolated from the bacteria Streptomyces venezuelae in 1948 and was the first bulk produced synthetic antibiotic. However, chloramphenicol is a rarely used drug in the United States because of its known severe adverse effects, such as bone marrow toxicity and grey baby syndrome. Chloramphenicol is not known to cause lethal arrhythmias, malignant hypertension, or status epilepticus. Option A: Chloramphenicol is associated with severe hematological side effects when administered systemically. Since 1982, chloramphenicol has reportedly caused fatal aplastic anemia, with possible increased risk when taken together with cimetidine. This adverse side effect can occur even with the topical administration of the drug, which is most likely due to the systemic absorption of the drug after topical application. Option B: Besides causing fatal aplastic anemia and bone marrow suppression, other side effects of chloramphenicol include ototoxicity with the use of topical ear drops, gastrointestinal reactions such as oesophagitis with oral use, neurotoxicity, and severe metabolic acidosis. Option C: Optic neuritis is the most commonly associated neurotoxic complication that can arise from chloramphenicol use. This adverse effect usually takes more than six weeks to manifest, presenting with either acute or subacute vision loss, with possible fundal changes. It may also present with peripheral neuropathy, which may present as numbness or tingling. If optic neuropathy occurs, the drug should be withdrawn immediately, which will usually lead to partial or complete recovery of vision.

Answer 58

Correct Answer: D. Altered peripheral tissue perfusion related to venous congestion. Altered peripheral tissue perfusion related to venous congestion” takes highest priority because venous inflammation and clot formation impede blood flow in a patient with deep-vein thrombosis. A deep-vein thrombosis (DVT) is a blood clot that forms within the deep veins, usually of the leg, but can occur in the veins of the arms and the mesenteric and cerebral veins. Deep-vein thrombosis is a common and important disease. It is part of the venous thromboembolism disorders which represent the third most common cause of death from cardiovascular disease after heart attacks and stroke. Option A: Option A is incorrect because impaired gas exchange is related to decreased, not increased, blood flow. Depending on the relative balance between the coagulation and thrombolytic pathways, thrombus propagation occurs. DVT is commonest in the lower limb below the knee and starts at low-flow sites, such as the soleal sinuses, behind venous valve pockets. Option B: Option B is inappropriate because no evidence suggests that this patient has a fluid volume excess. Nurses need to educate the patients on the importance of ambulation, being compliant with compression stockings, and taking the prescribed anticoagulation medications. Option C: Option C may be warranted but is secondary to altered tissue perfusion. Thrombosis is a protective mechanism that prevents the loss of blood and seals off damaged blood vessels. Fibrinolysis counteracts or stabilizes the thrombosis. The triggers of venous thrombosis are frequently multifactorial, with the different parts of the triad of Virchow contributing in varying degrees in each patient, but all result in early thrombus interaction with the endothelium. This then stimulates local cytokine production and causes leukocyte adhesion to the endothelium, both of which promote venous thrombosis.

Answer 59

Correct Answer: A. Superior vena cava When the central venous catheter is positioned correctly, its tip lies in the superior vena cava, inferior vena cava, or the right atrium—that is, in central venous circulation. Blood flows unimpeded around the tip, allowing the rapid infusion of large amounts of fluid directly into circulation. The basilica, jugular, and subclavian veins are common insertion sites for central venous catheters. Option B: There are three main access sites for the placement of central venous catheters. The internal jugular vein, common femoral vein, and subclavian veins are the preferred sites for temporary central venous catheter placement. Additionally, for mid-term and long-term central venous access, the basilic and brachial veins are utilized for peripherally inserted central catheters (PICCs). Option C: The internal jugular vein (IJ) is often chosen for its reliable anatomy, accessibility, low complication rates, and the ability to employ ultrasound guidance during the procedure. The individual clinical scenario may dictate laterality in some cases (such as with trauma, head and neck cancer, or the presence of other invasive devices or catheters), but all things being equal, many physicians prefer the right IJ. As compared to the left, the right IJ forms a more direct path to the superior vena cava (SVC) and right atrium. It is also wider in diameter and more superficial, thus presumably easier to cannulated. Option D: The subclavian vein site has the advantage of low rates of both infectious and thrombotic complications. Additionally, the SC site is accessible in trauma, when a cervical collar negates the choice of the IJ. However, disadvantages include a higher relative risk of pneumothorax, less accessibility to use ultrasound for CVC placement, and the non-compressible location posterior to the clavicle.

Answer 60

During the evaluation step of the nursing process, the nurse determines whether the goals established in the care plan have been achieved, and evaluates the success of the plan. If a goal is unmet or partially met the nurse reexamines the data and revises the plan. This final step of the nursing process is vital to a positive patient outcome. Whenever a healthcare provider intervenes or implements care, they must reassess or evaluate to ensure the desired outcome has been met. Reassessment may frequently be needed depending upon overall patient condition. The plan of care may be adapted based on new assessment data. Assessment involves data collection. Planning involves setting priorities, establishing goals, and selecting appropriate interventions. Option A: Assessment is the first step and involves critical thinking skills and data collection; subjective and objective. Subjective data involves verbal statements from the patient or caregiver. Objective data is measurable, tangible data such as vital signs, intake and output, and height and weight. Option B: The planning stage is where goals and outcomes are formulated that directly impact patient care based on EDP guidelines. These patient-specific goals and the attainment of such assist in ensuring a positive outcome. Nursing care plans are essential in this phase of goal setting. Care plans provide a course of direction for personalized care tailored to an individual’s unique needs. Overall condition and comorbid conditions play a role in the construction of a care plan. Care plans enhance communication, documentation, reimbursement, and continuity of care across the healthcare continuum. Option C: Implementation is the step that involves action or doing and the actual carrying out of nursing interventions outlined in the plan of care. This phase requires nursing interventions such as applying a cardiac monitor or oxygen, direct or indirect care, medication administration, standard treatment protocols, and EDP standards.

Answer 61

Correct Answer: C. “With your history and the type of location of the injury, it’s hard to say.” Wound healing in a client with diabetes will be delayed. Providing the client with a time frame could give the client false information. There is no doubt that diabetes plays a detrimental role in wound healing. It does so by affecting the wound healing process at multiple steps. Wound hypoxia, through a combination of impaired angiogenesis, inadequate tissue perfusion, and pressure-related ischemia, is a major driver of chronic diabetic wounds. Option A: Ischemia can lead to prolonged inflammation, which increases the levels of oxygen radicals, leading to further tissue injury. Elevated levels of matrix metalloproteases in chronic diabetic wounds, sometimes up to 50-100 times higher than acute wounds, cause tissue destruction and prevent normal repair processes from taking place. Furthermore, diabetes is associated with impaired immunity, with critical defects occurring at multiple points within the immune system cascade of the wound healing process. Option B: To further complicate matters, these wounds have defects in angiogenesis and neovascularization. Normally, wound hypoxia stimulates mobilization of endothelial progenitor cells via vascular endothelial growth factor (VEGF). In diabetic wounds, there are aberrant levels of VEGF and other angiogenic factors such as angiopoietin-1 and angiopoietin-2 that lead to dysangiogenesis. Option D: Diabetic neuropathy may also play a role in poor wound healing. Lower levels of neuropeptides, as well as reduced leukocyte infiltration as a result of sensory denervation, have been shown to impair wound healing. When combined, all these diverse factors play a role in the formation and propagation of chronic, debilitating wounds in patients with diabetes.

Answer 62

Correct Answer: B. Documenting drugs given. Although documentation isn’t a step in the nursing process, the nurse is legally required to document activities related to drug therapy, including the time of administration, the quantity, and the client’s reaction. Developing a content outline, establishing outcome criteria, and setting realistic client goals are part of planning rather than implementation. Option A: UE has a common goal with the pharmaceutical care it supports: to improve an individual patient’s quality of life through the achievement of predefined, medication-related therapeutic outcomes. Through its focus on the system of medication use, the MUE process helps to identify actual and potential medication-related problems, resolve actual medication-related problems, and prevent potential medication-related problems that could interfere with achieving optimum outcomes from medication therapy. Option C: Although distinctions historically have been made among the terms drug-use evaluation, drug-use review, and medication use evaluation (MUE), they all refer to the systematic evaluation of medication use employing standard, observational quality-improvement methods. MUE is a quality-improvement activity, but it also can be considered a formulary system management technique. An MUE is a performance improvement method that focuses on evaluating and improving medication-use processes with the goal of optimal patient outcomes. Option D: MUE encompasses the goals and objectives of drug use evaluation (DUE) in its broadest application, emphasizing improving patient outcomes. The use of MUE, rather than DUE, emphasizes the need for a more multifaceted approach to improving

Answer 63

Correct Answer: B. Recent pelvic surgery The client shows signs of deep vein thrombosis (DVT). The pelvic area is rich in blood supply, and thrombophlebitis of the deep vein is associated with pelvic surgery. Thrombosis is a protective mechanism that prevents the loss of blood and seals off damaged blood vessels. Fibrinolysis counteracts or stabilizes the thrombosis. The triggers of venous thrombosis are frequently multifactorial, with the different parts of the triad of Virchow contributing in varying degrees in each patient, but all result in early thrombus interaction with the endothelium. This then stimulates local cytokine production and causes leukocyte adhesion to the endothelium, both of which promote venous thrombosis. Option A: Aspirin, an antiplatelet agent, and an active walking program help decrease the client’s risk of DVT. The use of thrombolytic therapy can result in an intracranial bleed, and hence, careful patient selection is vital. Recently endovascular interventions like catheter-directed extraction, stenting, or mechanical thrombectomy have been tried with moderate success. Option C: Treatment of DVT aims to prevent pulmonary embolism, reduce morbidity, and prevent or minimize the risk of developing post-thrombotic syndrome. The cornerstone of treatment is anticoagulation. NICE guidelines only recommend treating proximal DVT (not distal) and those with pulmonary emboli. In each patient, the risks of anticoagulation need to be weighed against the benefits. Option D: In general, diabetes is a contributing factor associated with peripheral vascular disease. In the hospital, the most commonly associated conditions are malignancy, congestive heart failure, obstructive airway disease, and patients undergoing surgery. In the hospital, the most commonly associated conditions are malignancy, congestive heart failure, obstructive airway disease, and patients undergoing surgery.

Answer 64

Correct Answer: D. Provide the client with normal sleep aids, such as pillows, back rubs, and snacks The nurse should begin with the simplest interventions, such as pillows or snacks, before interventions that require greater skill such as relaxation techniques. Sleep is a complex biological process. It is a reversible state of unconsciousness in which there are reduced metabolism and motor activity. Sleep disorders are a group of conditions that disturb the normal sleep patterns of a person. Sleep disorders are one of the most common clinical problems encountered. Inadequate or non-restorative sleep can interfere with normal physical, mental, social, and emotional functioning. Sleep disorders can affect overall health, safety, and quality of life. Option A: Sleep medication should be avoided whenever possible. Histamine type 1 receptor blockers: due to their sedative effects, these drugs can be helpful in patients with sleep disorders. Benzodiazepines (BZD) are the mainstay in the treatment of insomnia. Non-benzodiazepine hypnotics are used for the treatment of acute and short term insomnia. Option B: At some point, the nurse should do a thorough sleep assessment, especially if common sense interventions fail. The sleep diary, or sleep log, is a subjective paper record of sleep and wakefulness over a period of weeks to a month. Patients should record the detailed description of sleep, such as bedtime, duration until sleep onset, the number of awakenings, duration of awakenings, and nap times. Option C: Relaxation techniques may be implemented before sleep. Meditation and breathing exercises are some of the relaxation techniques. It begins with being in a comfortable position and closing eyes. The mind and thoughts should be redirected towards a peaceful image, and relaxation should be allowed to spread throughout the body.

Answer 65

Correct Answer: C. Moist, sterile saline gauze Moist, sterile saline dressings support would heal and are cost-effective. If the wound is infected and there are a lot of sloughs, which cannot be mechanically debrided, then a chemical debridement can be done with collagenase-based products. The goal is to help the wound heal as soon as possible by using an appropriate dressing material to maintain the right amount of moisture. When the wound bed is dry, use a dressing to increase moisture and if too wet and the surrounding skin is macerated, use material that will absorb excess fluid and protect the surrounding healthy skin. Option A: Dry sterile dressings adhere to the wound and debride the tissue when removed. Tulle is a non-adherent dressing impregnated with paraffin. It aids healing but doesn’t absorb exudate. It also requires a secondary dressing to hold it in place. It is ideal for burns as one can add topical antibiotics to the dressing. It is known to cause allergies, and this limits its wider use. Option B: Petroleum supports healing but is expensive. The semipermeable dressing allows for moisture to evaporate and also reduces pain. This dressing also acts as a barrier to prevent environmental contamination. The semipermeable dressing does not absorb moisture and requires regular inspection. It also requires a secondary dressing to hold the semipermeable dressing in place. Option D: Povidone-iodine can irritate epithelial cells, so it shouldn’t be left on an open wound. Plastic film dressings are known to absorb exudate and can be used for wounds with a moderate amount of exudate. They should not be used on dry wounds. They often require a secondary dressing to hold the plastic in place.

Answer 66

Correct Answer: C. Upcoding Upcoding is the practice of using a CPT code that’s reimbursed at a higher rate than the code for the service actually provided. Upcoding is fraudulent medical billing in which a bill sent for a health service is more expensive than it should have been based on the service that was performed. An upcoded bill can be sent to any payer—whether a private health insurer, Medicaid, Medicare, or the patient. Unbundling, overbilling, and misrepresentation aren’t the terms used for this illegal practice. Option A: Unbundling refers to using multiple CPT codes for those parts of the procedure, either due to misunderstanding or in an effort to increase payment. Option B: Overbilling (sometimes spelled as over-billing) is the practice of charging more than is legally or ethically acceptable on an invoice or bill. Option D: A misrepresentation is a false statement of a material fact made by one party which affects the other party’s decision in agreeing to a contract. If the misrepresentation is discovered, the contract can be declared void, and depending on the situation, the adversely impacted party may seek damages.

Answer 67

Correct Answer: D. Suggest referral to a sex counselor or other appropriate professional The nurse should refer this client to a sex counselor or other professional. Making appropriate referrals is a valid part of planning the client’s care. Therefore, providing time for privacy and providing support for the spouse or significant other are important, but not as important as referring the client to a sex counselor. Option A: The nurse doesn’t normally provide sex counseling. The nurse is ideally placed in the primary care field to help ease the upset caused; however, in order to offer care that is effective, insight and understanding of the condition are required as well as the various treatment options available to help men manage their health and wellbeing. Option B: The key goal of management is to diagnose and treat the cause of ED when this is possible, enabling the man or couple to enjoy a satisfactory sexual experience. This can occur when the nurse has identified and treated any curable causes of ED, initiating lifestyle change and risk factor modification, including drug-related factors, and offering education and counselling to patients and their partners. Option C: The potential benefits of lifestyle changes (e.g. weight management, smoking cessation) may be particularly important in individuals with ED and specific comorbid cardiovascular or metabolic diseases, such as diabetes or hypertension. As well as improving erectile function, lifestyle changes may also benefit overall cardiovascular and metabolic health. Further studies are needed to clarify the role of lifestyle changes in the management of ED and related cardiovascular disease.

Answer 68

Correct Answer: B. Elimination According to Maslow, elimination is a first-level or physiological need and therefore takes priority over all other needs. In 1943, Abraham Maslow developed a hierarchy based on basic fundamental needs innate for all individuals. Maslow’s hierarchy of needs is a motivational theory in psychology comprising a five-tier model of human needs, often depicted as hierarchical levels within a pyramid. From the bottom of the hierarchy upwards, the needs are: physiological (food and clothing), safety (job security), love and belonging needs (friendship), esteem, and self-actualization. Security and safety are second-level needs; belonging is a third-level need. Second- and third-level needs can be met only after a client’s first-level needs have been satisfied. Option A: Once an individual’s physiological needs are satisfied, the needs for security and safety become salient. People want to experience order, predictability, and control in their lives. These needs can be fulfilled by the family and society (e.g. police, schools, business, and medical care). Option C: Physiological and safety needs provide the basis for the implementation of nursing care and nursing interventions. For example, emotional security, financial security (e.g. employment, social welfare), law and order, freedom from fear, social stability, property, health, and wellbeing (e.g. safety against accidents and injury). Option D: After physiological and safety needs have been fulfilled, the third level of human needs is social and involves feelings of belongingness. The need for interpersonal relationships motivates behavior. Examples include friendship, intimacy, trust, and acceptance, receiving and giving affection and love. Affiliating, being part of a group (family, friends, work)

Answer 69

Correct Answer: B. Inadequate protein intake. A client on bed rest suffers from a lack of movement and a negative nitrogen balance. Therefore, inadequate protein intake impairs wound healing. Decubitus ulcers, also termed bedsores or pressure ulcers, are skin and soft tissue injuries that form as a result of constant or prolonged pressure exerted on the skin. These ulcers occur at bony areas of the body such as the ischium, greater trochanter, sacrum, heel, malleolus (lateral than medial), and occiput. Inadequate vitamin D intake and low calcium levels aren’t factors in poor healing for this client. A pressure ulcer should never be massaged. Option A: Decubitus ulcer formation is multifactorial (external and internal factors), but all these results in a common pathway leading to ischemia and necrosis. Tissues can sustain an abnormal amount of external pressure, but constant pressure exerted over a prolonged period is the main culprit. Option C: External pressure must exceed the arterial capillary pressure (32 mmHg) to impede blood flow and must be greater than the venous capillary closing pressure (8 to 12 mmHg) to impair the return of venous blood. If the pressure above these values is maintained, it causes tissue ischemia and further resulting in tissue necrosis. This enormous pressure can be exerted due to compression by a hard mattress, railings of hospital beds, or any hard surface with which the patient is in contact. Option D: Friction caused by skin rubbing against surfaces like clothing or bedding can also lead to the development of ulcers by contributing to breaks in the superficial layers of the skin. Moisture can cause ulcers and worsens existing ulcers via tissue breakdown and maceration.

Answer 70

Correct Answer: D. Risk for aspiration related to anesthesia. Risk for aspiration related to anesthesia takes priority for this client because general anesthesia may impair the gag and swallowing reflexes, possibly leading to aspiration. The gag reflex, also known as the pharyngeal reflex, is a reflex contraction of the muscles of the posterior pharynx after stimulation of the posterior pharyngeal wall, tonsillar area, or base of the tongue. The gag reflex is believed to be an evolutionary reflex that developed as a method to prevent the aspiration of solid food particles. It is an essential component of evaluating the medullary brainstem and plays a role in the declaration of brain death.The other options, although important, are secondary. Option A: Postoperative pain can additionally characterize as somatic or visceral. The somatic division of pain is composed of a rich input of nociceptive myelinated, rapidly conducting A-beta-fibers found in cutaneous and deep tissue, which contribute to a more localized, sharp quality. The visceral division of pain is composed of a network of unmyelinated C-fibers and thinly myelinated A-delta-fibers that span across multiple viscera and converge together before entering the spinal cord. Also, visceral afferent fibers run close to autonomic ganglia before their entrance into the dorsal root of the spinal cord. These characteristic features of visceral nociceptive fibers are what contribute to a more diffuse, poorly localized pattern of pain that may be accompanied by autonomic reactions such as a change in heart rate or blood pressure. Option B: The acid-base and electrolyte changes observed in the perioperative period could be secondary to the underlying illness or surgical procedure, for example, hyponatremia occurring with transurethral resection of the prostate where glycine or other hypotonic fluid is used for irrigation. Serum sodium concentration <120 mmol/L will cause confusion and irritability, whereas <110 mmol/L may cause seizures and coma. Option C: Complete physiologic recovery takes place by 40 min in 40% of the patients. The functional quality of recovery in all domains occurs in only 11% of the patients by day 3. Thus, the concept of awakening is involved with far greater dimensions than judging the anesthetic effect as terminated and assessing a patient as being “recovered” or “awakened.” Patients cannot be considered fully recovered until they have returned to their preoperative physiological state.

Answer 71

Correct Answer: C. Petechiae Petechiae are small hemorrhagic spots. Petechiae are tiny purple, red, or brown spots on the skin. They usually appear on the arms, legs, stomach, and buttocks. They can also be found inside the mouth or on the eyelids. These pinpoint spots can be a sign of many different conditions — some minor, others serious. They can also appear as a reaction to certain medications. Option A: Extravasation is the leakage of fluid in the interstitial space. Extravasation is the leakage of a fluid out of its container into the surrounding area, especially blood or blood cells from vessels. In the case of inflammation, it refers to the movement of white blood cells from the capillaries to the tissues surrounding them (leukocyte extravasation, also known as diapedesis). Option B: Osteomalacia is the softening of bone tissue. Osteomalacia refers to a marked softening of the bones, most often caused by severe vitamin D deficiency. The softened bones of children and young adults with osteomalacia can lead to bowing during growth, especially in weight-bearing bones of the legs. Osteomalacia in older adults can lead to fractures. Option D: Uremia is an excess of urea and other nitrogen products in the blood. Uremia is the condition of having high levels of urea in the blood. Urea is one of the primary components of urine. It can be defined as an excess of amino acid and protein metabolism end products, such as urea and creatinine, in the blood that would be normally excreted in the urine.

Answer 72

Correct Answer: B. Patient’s Bill of Rights The Patient’s Bill of Rights addresses the client’s right to information, informed consent, timely responses to requests for services, and treatment refusal. A legal document, it serves as a guideline for the nurse’s decision making. Standards of Nursing Practice, the Nurse Practice Act, and the Code for Nurses contain nursing practice parameters and primarily describe the use of the nursing process in providing care. Option A: Standards of nursing practice developed by the American Nurses’ Association (ANA) provide guidelines for nursing performance. They are the rules or definition of what it means to provide competent care. The registered professional nurse is required by law to carry out care in accordance with what other reasonably prudent nurses would do in the same or similar circumstances. Thus, provision of high-quality care consistent with established standards is critical. Option C: Every state and territory in the US set laws to govern the practice of nursing. These laws are defined in the Nursing Practice Act (NPA). The NPA is then interpreted into regulations by each state and territorial nursing board with the authority to regulate the practice of nursing care and the power to enforce the laws. Option D: The ANA Code of Ethics for Nurses serves the following purposes: It is a succinct statement of the ethical obligations and duties of every individual who enters the nursing profession. It is the profession’s nonnegotiable ethical standard. It is an expression of nursing’s own understanding of its commitment to society.

Answer 73

Correct Answer: B. Produce a false-high measurement. Using an undersized blood pressure cuff produces a falsely elevated blood pressure because the cuff can’t record brachial artery measurements unless it’s excessively inflated. Option A: Using a blood pressure cuff that’s too large or too small can give inaccurate blood pressure readings. The doctor’s office should have several sizes of cuffs to ensure an accurate blood pressure reading. When one measures their blood pressure at home, it’s important to use the proper size cuff. Option C: The sciatic nerve wouldn’t be damaged by hyperinflation of the blood pressure cuff because the sciatic nerve is located in the lower extremity. Option D: The inflatable part of the blood pressure cuff should cover about 40% of the distance around (circumference of) the upper arm. The cuff should cover 80% of the area from the elbow to the shoulder.

Answer 74

Correct Answer: A. Baked beans, hamburger, and milk Baked beans, hamburger, and milk are all excellent sources of protein. Good choices include soy protein, beans, nuts, fish, skinless poultry, lean beef, pork, and low-fat dairy products. Avoid processed meats. Option B: The spaghetti-broccoli-tea choice is high in carbohydrates. The quality of the carbohydrates (carbs) one eats is important too. Cut processed carbs from the diet, and choose carbs that are high in fiber and nutrient-dense, such as whole grains and vegetables and fruit. Option C: The bouillon-spinach-soda choice provides liquid and sodium as well as some iron, vitamins, and carbohydrates. Option D: Chicken provides protein but the chicken-spinach-soda combination provides less protein than the baked beans-hamburger-milk selection.

Answer 75

Correct Answer: A. Assess the client’s airway. The first priority is to evaluate airway patency before assessing for signs of obstruction, sternal retraction, stridor, or wheezing. Airway management is always the nurse’s first priority. Blunt trauma, on the whole, is a more common cause of traumatic injuries and can be equally life-threatening. It is important to know the mechanism as management may be different. Most blunt trauma is managed non-operatively, whereas penetrating chest trauma often requires operative intervention. Pain management and splinting are important for the client’s comfort but would come after airway assessment. Option B: Pain control greatly affects mortality and morbidity in patients with chest trauma. Pain leads to splints which worsen or prevent healing. In many cases, it can lead to pneumonia. Early analgesia should be considered to decrease splinting. In the acute setting, push doses of short-acting narcotics should be used. Option C: Coughing and deep breathing may be contraindicated if the client has internal bleeding and other injuries. Minor injuries may simply require close monitoring and pain control. Care should be taken in the young and the elderly. Patients with 3 or more rib fractures, a flail segment, and any number of rib fractures with pulmonary contusions, hemopneumothorax, hypoxia, or pre-existing pulmonary disease should be monitored at an advanced level of care. Option D: Immediate life-threatening injuries require prompt intervention, such as emergent tube thoracostomy for large pneumothoraces, and initial management of hemothorax. For cases of hemothorax, adequate drainage is imperative to prevent retained hemothorax. Retained hemothorax can lead to empyema requiring video-assisted thoracoscopic surgery.

Answer 76

Correct Answer: B. Unexpected feelings and emotions among the staff. The usual or most prevalent reason for lack of productivity in a group of competent nurses is inadequate communication or a situation in which the nurses have unexpected feelings and emotions. Although the other options could be contributing to the problematic situation, they’re less likely to be the cause. Option A: Providing employees with acknowledgment of the good work that they have done is one of the easiest management tasks. However, it is also as easily neglected. For instance, a study in the financial sector shows that only 20% of employees feel strongly valued at work. Option C: Another big issue that causes low productivity is workplace stress. A study by Health Advocate shows that there are about one million employees who are suffering from low productivity due to stress, which costs companies $600 dollars per worker every single year. Option D: An important reason for low employee productivity might be the fact that they do not feel that they belong with the company that they are part of. It is important for every manager to make sure that the environment in their business is welcoming to new hires and does not make them feel underappreciated

Answer 77

Correct Answer: B. Prevent infection The client is at risk for infection because WBC count is dangerously low. Neutrophils play an essential role in immune defenses because they ingest, kill, and digest invading microorganisms, including fungi and bacteria. Failure to carry out this role leads to immunodeficiency, which is mainly characterized by the presence of recurrent infections. Hb level and HCT are within normal limits; therefore, fluid balance, rest, and prevention of injury are inappropriate. Option A: Neutrophils play a role in the immune defense against extracellular bacteria, including Staphylococci, Streptococci, and Escherichia coli, among others. They also protect against fungal infections, including those produced by Candida albicans. Once their count is below 1 x 10/L recurrent infections start. As compensation, the monocyte count may increase. Option C: Application of granulocyte-colony stimulating factor (G-CSF) can improve neutrophil functions and number. Prophylactic use of antibiotics and antifungals is reserved for some forms of alteration in neutrophil function such as chronic granulomatous disease CGD). Option D: In primary neutropenia disorders such as chronic granulomatous disease presents with recurrent infections affecting many organs since childhood. It is caused by a failure to produce toxic reactive oxygen species so that the neutrophils can ingest the microorganisms, but they are unable to kill them, as a significant consequence granuloma can obstruct organs such as the stomach, esophagus, or bladder. Patients with this disease are very susceptible to opportunistic infections by certain bacteria and fungi, especially with Serratia and Burkholderia.

Answer 78

Correct Answer: D. Side-lying Because of lethargy, the post-tonsillectomy client is at risk for aspirating blood from the surgical wound. Therefore, placing the client in the side-lying position until he awake is best. The semi-Fowler’s, supine, and high-Fowler’s position don’t allow for adequate oral drainage in a lethargic post-tonsillectomy client and increase the risk of blood aspiration. Option A: Semi-Fowler’s would not be able to facilitate effective drainage. Bleeding is one of the most common and feared complications following tonsillectomy with or without adenoidectomy. A study from 2009 to 2013 involving over one hundred thousand children showed that 2.8% of children had unplanned revisits for bleeding following tonsillectomy, 1.6% percent of patients came through the emergency department, and 0.8% required a procedure. Option B: Supine position predisposes the patient to aspiration. Frequency is higher at night with 50% of bleeding occurring between 10pm-1am and 6am-9am; this is thought to be from changes in circadian rhythm, vibratory effects of snoring on the oropharynx, or drying of the oropharyngeal mucosa from mouth breathing. Risk of bleeding in patients with known coagulopathies may be significantly higher. Option C: Tonsillectomy can be either extracapsular or intracapsular. The “hot” extracapsular technique with monopolar cautery is the most popular technique in the United States.

Answer 79

Correct Answer: A. Anisocoria Unequal pupils are called anisocoria. Anisocoria, or unequal pupil sizes, is a common condition. The varied causes have implications ranging from life-threatening to completely benign, and a clinically guided history and examination is the first step in establishing a diagnosis. Option B: Ataxia is uncoordinated actions of involuntary muscle use. Ataxia is a degenerative disease of the nervous system. Many symptoms of Ataxia mimic those of being drunk, such as slurred speech, stumbling, falling, and incoordination. These symptoms are caused by damage to the cerebellum, the part of the brain that is responsible for coordinating movement. Option C: A cataract is an opacity of the eye’s lens. A cataract is a clouding of the normally clear lens of the eye. For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it more difficult to read, drive a car (especially at night) or see the expression on a friend’s face. Option D: Diplopia is double vision. Diplopia is the perception of 2 images of a single object. Diplopia may be monocular or binocular. Monocular diplopia is present when only one eye is open. Binocular diplopia disappears when either eye is closed.

Answer 80

Correct Answer: A. He may have a low threshold for pain. People of Italian heritage tend to verbalize discomfort and pain. The pain was real to the client, and he may need medication when he wakes up. Italian females reported the highest sensitivity to both mechanical and electrical stimulation, while Swedes reported the lowest sensitivity. Mechanical pain thresholds differed more across cultures than did electrical pain thresholds. Cultural factors may influence response to type of pain test. Option B: Our pain threshold is the minimum point at which something, such as pressure or heat, causes us pain. For example, someone with a lower pain threshold might start feeling pain when only minimal pressure is applied to part of their body. Pain tolerance and threshold varies from person to person. Option C: When we feel pain, nearby nerves send signals to the brain through the spinal cord. The brain interprets this signal as a sign of pain, which can set off protective reflexes. For example, when one touches something very hot, the brain receives signals indicating pain. This in turn can make one quickly pull the hand away without even thinking. Option D: Biofeedback is a type of therapy that helps increase the awareness of how the body responds to stressors and other stimuli. This includes pain. During a biofeedback session, a therapist will teach the client how to use relaxation techniques, breathing exercises, and mental exercises to override the body’s response to stress or pain.

Answer 81

Correct Answer: D. Fluid overload Fluid overload causes the volume of blood within the vascular system to increase. This increase causes the vein to distend, which can be seen most obviously in the neck veins. JVD is a sign of increased central venous pressure (CVP). That’s a measurement of the pressure inside the vena cava. CVP indicates how much blood is flowing back into the heart and how well the heart can move that blood into the lungs and the rest of the body. Option A: A neck tumor doesn’t typically cause jugular vein distention. Right-sided heart failure is a common cause. Right-sided heart failure usually develops after a left-sided heart failure. The left ventricle pumps blood out through the aorta to most of the body. The right ventricle pumps blood to the lungs. When the left ventricle’s pumping power weakens, fluid can back up into the lungs. This eventually weakens the right ventricle. Option B: An electrolyte imbalance may result in fluid overload, but it doesn’t directly contribute to jugular vein distention. The pericardium is a thin, fluid-filled sac that surrounds the heart. An infection of the pericardium, called constrictive pericarditis, can restrict the volume of the heart. As a result, the chambers can’t fill with blood properly, so blood can back up into veins, including the jugular veins. Option C: Dehydration does not cause JVD. Another common cause is pulmonary hypertension. Pulmonary hypertension occurs when the pressure in your lungs increases, sometimes as a result of changes to the lining of the artery walls. This can also lead to right-sided heart failure.
