Q

Stacy is diagnosed with acute lymphoid leukemia (ALL) and beginning chemotherapy. Stacy’s mother states to the nurse that it is hard to see Stacy with no hair. The best response for the nurse is:

A. “Stacy looks very nice wearing a hat”.
B. “You should not worry about her hair, just be glad that she is alive”.
C. “Yes, it is upsetting. But try to cover up your feelings when you are with her or else she may be upset”.
D. “This is only temporary; Stacy will re-grow new hair in 3-6 months but may be different in texture”.

A

D. “This is only temporary; Stacy will re-grow new hair in 3-6 months but may be different in texture”.

Option D: This is the appropriate response. The nurse should help the mother how to cope with her own feelings regarding the child’s disease so as not to affect the child negatively. When the hair grows back, it is still of the same color and texture.

Q

When Mr. Gonzales regained consciousness, the physician orders 50 ml of Lactulose p.o. every 2 hours. Mr. Gonzales develops diarrhea. The nurse best action would be:

A. “I’ll see if your physician is in the hospital”.
B. “Maybe you’re reacting to the drug; I will withhold the next dose”.
C. “I’ll lower the dosage as ordered so the drug causes only 2 to 4 stools a day”.
D. “Frequently, bowel movements are needed to reduce sodium level”.

A

C. “I’ll lower the dosage as ordered so the drug causes only 2 to 4 stools a day”.

Option C: Lactulose is given to a patient with hepatic encephalopathy to reduce absorption of ammonia in the intestines by binding with ammonia and promoting more frequent bowel movements. If the patient experience diarrhea, it indicates overdosage and the nurse must reduce the amount of medication given to the patient. The stool will be mushy or soft. Lactulose is also very sweet and may cause cramping and bloating.

Q

Which of the following groups of symptoms indicates a ruptured abdominal aortic aneurysm?

A. Lower back pain, increased blood pressure, decreased red blood cell (RBC) count, increased white blood (WBC) count.
B. Severe lower back pain, decreased blood pressure, decreased RBC count, increased WBC count.
C. Severe lower back pain, decreased blood pressure, decreased RBC count, decreased RBC count, decreased WBC count.
D. Intermittent lower back pain, decreased blood pressure, decreased RBC count, increased WBC count.

A

B. Severe lower back pain, decreased blood pressure, decreased RBC count, increased WBC count.

Option B: Severe lower back pain indicates an aneurysm rupture, secondary to pressure being applied within the abdominal cavity. When rupture occurs, the pain is constant because it can’t be alleviated until the aneurysm is repaired. Blood pressure decreases due to the loss of blood. After the aneurysm ruptures, the vasculature is interrupted and blood volume is lost, so blood pressure wouldn’t increase. For the same reason, the RBC count is decreased – not increased. The WBC count increases as cell migrate to the site of injury.

A. “Your son had a mild concussion, acetaminophen is strong enough.”
B. “Aspirin is avoided because of the danger of Reye’s syndrome in children or young adults.”
C. “Narcotics are avoided after a head injury because they may hide a worsening condition.”
D. “Stronger medications may lead to vomiting, which increases the intracranial pressure (ICP).”

A

C. Narcotics are avoided after a head injury because they may hide a worsening condition.

Option C: Narcotics may mask changes in the level of consciousness that indicate increased ICP.

Option A: Acetaminophen is strong enough ignores the mother’s question and therefore isn’t appropriate.
Option B: Aspirin is contraindicated in conditions that may have bleeding, such as trauma, and for children or young adults with viral illnesses due to the danger of Reye’s syndrome.
Option D: Stronger medications may not necessarily lead to vomiting but will sedate the client, thereby masking changes in his level of consciousness.

Q

When evaluating an arterial blood gas from a male client with a subdural hematoma, the nurse notes the Paco2 is 30 mm Hg. Which of the following responses best describes the result?

A. Appropriate; lowering carbon dioxide (CO2) reduces intracranial pressure (ICP)
B. Emergent; the client is poorly oxygenated
C. Normal
D. Significant; the client has alveolar hypoventilation

A

A. Appropriate; lowering carbon dioxide (CO2) reduces intracranial pressure (ICP)

Option A: A normal Paco2 value is 35 to 45 mm Hg CO2 has vasodilating properties; therefore, lowering Paco2 through hyperventilation will lower ICP caused by dilated cerebral vessels.

Option B: Oxygenation is evaluated through Pao2 and oxygen saturation.
Option D: Alveolar hypoventilation would be reflected in an increased Paco2.

22
Q

When prioritizing care, which of the following clients should the nurse Olivia assess first?

A. A 17-year-old client 24-hours post appendectomy
B. A 33-year-old client with a recent diagnosis of Guillain-Barre syndrome
C. A 50-year-old client 3 days post myocardial infarction
D. A 50-year-old client with diverticulitis

A

B. A 33-year-old client with a recent diagnosis of Guillain-Barre syndrome

Option B: Guillain-Barre syndrome is characterized by ascending paralysis and potential respiratory failure. The order of client assessment should follow client priorities, with disorder of airways, breathing, and then circulation. There’s no information to suggest the postmyocardial infarction client has an arrhythmia or other complication. There’s no evidence to suggest hemorrhage or perforation for the remaining clients as a priority of care.

A

C. Myxedema coma

Myxedema coma, severe hypothyroidism, is a life-threatening condition that may develop if thyroid replacement medication isn’t taken.

26
Q

Nurse Sugar is assessing a client with Cushing’s syndrome. Which observation should the nurse report to the physician immediately?

A. Pitting edema of the legs
B. An irregular apical pulse
C. Dry mucous membranes
D. Frequent urination

A

B. An irregular apical pulse

Option B: Because Cushing’s syndrome causes aldosterone overproduction, which increases urinary potassium loss, the disorder may lead to hypokalemia. Therefore, the nurse should immediately report signs and symptoms of hypokalemia, such as an irregular apical pulse, to the physician.

Option A: Edema is an expected finding because aldosterone overproduction causes sodium and fluid retention.
Options C and D: Dry mucous membranes and frequent urination signal dehydration, which isn’t associated with Cushing’s syndrome.

27
Q

Cyrill with severe head trauma sustained in a car accident is admitted to the intensive care unit. Thirty-six hours later, the client’s urine output suddenly rises above 200 ml/hour, leading the nurse to suspect diabetes insipidus. Which laboratory findings support the nurse’s suspicion of diabetes insipidus?

A. Above-normal urine and serum osmolality levels
B. Below-normal urine and serum osmolality levels
C. Above-normal urine osmolality level, below-normal serum osmolality level
D. Below-normal urine osmolality level, above-normal serum osmolality level

A

D. Below-normal urine osmolality level, above-normal serum osmolality level

Option D: In diabetes insipidus, excessive polyuria causes dilute urine, resulting in a below-normal urine osmolality level. At the same time, polyuria depletes the body of water, causing dehydration that leads to an above-normal serum osmolality level.

Options A, B, and C: For the same reasons, diabetes insipidus doesn’t cause above-normal urine osmolality or below-normal serum osmolality levels.

28
Q

Jomari is diagnosed with hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is stabilized and prepared for discharge. When preparing the client for discharge and home management, which of the following statements indicates that the client understands her condition and how to control it?

A. “I can avoid getting sick by not becoming dehydrated and by paying attention to my need to urinate, drink, or eat more than usual.”
B. “If I experience trembling, weakness, and headache, I should drink a glass of soda that contains sugar.”
C. “I will have to monitor my blood glucose level closely and notify the physician if it’s constantly elevated.”
D. “If I begin to feel especially hungry and thirsty, I’ll eat a snack high in carbohydrates.”

A

A. “I can avoid getting sick by not becoming dehydrated and by paying attention to my need to urinate, drink, or eat more than usual.”

Option A: Inadequate fluid intake during hyperglycemic episodes often leads to HHNS. By recognizing the signs of hyperglycemia (polyuria, polydipsia, and polyphagia) and increasing fluid intake, the client may prevent HHNS.

Option B: Drinking a glass of non-diet soda would be appropriate for hypoglycemia.
Option C: A client whose diabetes is controlled with oral antidiabetic agents usually doesn’t need to monitor blood glucose levels.
Option D: A high carbohydrate diet would exacerbate the client’s condition, particularly if fluid intake is low.

29
Q

A 66-year-old client has been complaining of sleeping more, increased urination, anorexia, weakness, irritability, depression, and bone pain that interferes with her going outdoors. Based on these assessment findings, the nurse would suspect which of the following disorders?

A. Diabetes mellitus
B. Diabetes insipidus
C. Hypoparathyroidism
D. Hyperparathyroidism

A

D. Hyperparathyroidism

Option D: Hyperparathyroidism is most common in older women and is characterized by bone pain and weakness from excess parathyroid hormone (PTH). Clients also exhibit hypercalciuria-causing polyuria.

Options A and B: While clients with diabetes mellitus and diabetes insipidus also have polyuria, they don’t have bone pain and increased sleeping.
Option C: Hypoparathyroidism is characterized by urinary frequency rather than polyuria.

30
Q

Nurse Lourdes is teaching a client recovering from Addisonian crisis about the need to take fludrocortisone acetate and hydrocortisone at home. Which statement by the client indicates an understanding of the instructions?

A. “I’ll take my hydrocortisone in the late afternoon, before dinner.”
B. “I’ll take all of my hydrocortisone in the morning, right after I wake up.”
C. “I’ll take two-thirds of the dose when I wake up and one-third in the late afternoon.”
D. “I’ll take the entire dose at bedtime.”

A

C. “I’ll take two-thirds of the dose when I wake up and one-third in the late afternoon.”

Option C: Hydrocortisone, a glucocorticoid, should be administered according to a schedule that closely reflects the body’s own secretion of this hormone; therefore, two-thirds of the dose of hydrocortisone should be taken in the morning and one-third in the late afternoon. This dosage schedule reduces adverse effects.

31
Q

Which of the following laboratory test results would suggest to the nurse Len that a client has a corticotropin-secreting pituitary adenoma?

A. High corticotropin and low cortisol levels
B. Low corticotropin and high cortisol levels
C. High corticotropin and high cortisol levels
D. Low corticotropin and low cortisol levels

A

C. High corticotropin and high cortisol levels

Option C: A corticotropin-secreting pituitary tumor would cause high corticotropin and high cortisol levels.

Options A and D: A high corticotropin level with a low cortisol level and a low corticotropin level with a low cortisol level would be associated with hypocortisolism.
Option B: Low corticotropin and high cortisol levels would be seen if there was a primary defect in the adrenal glands.

32
Q

A male client is scheduled for a transsphenoidal hypophysectomy to remove a pituitary tumor. Preoperatively, the nurse should assess for potential complications by doing which of the following?

A. Testing for ketones in the urine
B. Testing urine specific gravity
C. Checking temperature every 4 hours
D. Performing capillary glucose testing every 4 hours

A

D. Performing capillary glucose testing every 4 hours

Option D: The nurse should perform capillary glucose testing every 4 hours because excess cortisol may cause insulin resistance, placing the client at risk for hyperglycemia.

Option A: Urine ketone testing isn’t indicated because the client does secrete insulin and, therefore, isn’t at risk for ketosis.
Option B: Urine specific gravity isn’t indicated because although fluid balance can be compromised, it usually isn’t dangerously imbalanced.
Option C: Temperature regulation may be affected by excess cortisol and isn’t an accurate indicator of infection.

33
Q

Capillary glucose monitoring is being performed every 4 hours for a client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which he receives 8 U of regular insulin. Nurse Mariner should expect the dose’s:

A. onset to be at 2 p.m. and its peak to be at 3 p.m.
B. onset to be at 2:15 p.m. and its peak to be at 3 p.m.
C. onset to be at 2:30 p.m. and its peak to be at 4 p.m.
D. onset to be at 4 p.m. and its peak to be at 6 p.m.

A

Answer: C. onset to be at 2:30 p.m. and its peak to be at 4 p.m.

Option C: Regular insulin, which is a short-acting insulin, has an onset of 15 to 30 minutes and a peak of 2 to 4 hours. Because the nurse gave the insulin at 2 p.m., the expected onset would be from 2:15 p.m. to 2:30 p.m. and the peak from 4 p.m. to 6 p.m.

34
Q

The physician orders laboratory tests to confirm hyperthyroidism in a female client with classic signs and symptoms of this disorder. Which test result would confirm the diagnosis?

A. No increase in the thyroid-stimulating hormone (TSH) level after 30 minutes during the TSH stimulation test
B. A decreased TSH level
C. An increase in the TSH level after 30 minutes during the TSH stimulation test
D. Below-normal levels of serum triiodothyronine (T3) and serum thyroxine (T4) as detected by radioimmunoassay

A

Answer: A. No increase in the thyroid-stimulating hormone (TSH) level after 30 minutes during the TSH stimulation test

Option A: In the TSH test, failure of the TSH level to rise after 30 minutes confirms hyperthyroidism.

Option B: A decreased TSH level indicates a pituitary deficiency of this hormone.
Option D: Below-normal levels of T3 and T4, as detected by radioimmunoassay, signal hypothyroidism. A below-normal T4 level also occurs in malnutrition and liver disease and may result from administration of phenytoin and certain other drugs.

35
Q

Rico with diabetes mellitus must learn how to self-administer insulin. The physician has prescribed 10 U of U-100 regular insulin and 35 U of U-100 isophane insulin suspension (NPH) to be taken before breakfast. When teaching the client how to select and rotate insulin injection sites, the nurse should provide which instruction?

A. “Inject insulin into healthy tissue with large blood vessels and nerves.”
B. “Rotate injection sites within the same anatomic region, not among different regions.”
C. “Administer insulin into areas of scar tissue or hypotrophy whenever possible.”
D. “Administer insulin into sites above muscles that you plan to exercise heavily later that day.”

A

B. “Rotate injection sites within the same anatomic region, not among different regions.”

Option B: The nurse should instruct the client to rotate injection sites within the same anatomic region. Rotating sites among different regions may cause excessive day-to-day variations in the blood glucose level; also, insulin absorption differs from one region to the next.

Option A: Insulin should be injected only into healthy tissue lacking large blood vessels, nerves, or scar tissue or other deviations.
Option C: Injecting insulin into areas of hypertrophy may delay absorption. The client shouldn’t inject insulin into areas of lipodystrophy (such as hypertrophy or atrophy); to prevent lipodystrophy, the client should rotate injection sites systematically.
Option D: Exercise speeds drug absorption, so the client shouldn’t inject insulin into sites above muscles that will be exercised heavily.

36
Q

Nurse Sarah expects to note an elevated serum glucose level in a client with hyperosmolar hyperglycemic nonketotic syndrome (HHNS). Which other laboratory finding should the nurse anticipate?

A. Elevated serum acetone level
B. Serum ketone bodies
C. Serum alkalosis
D. Below-normal serum potassium level

A

D. Below-normal serum potassium level

Option D: A client with HHNS has an overall body deficit of potassium resulting from diuresis, which occurs secondary to the hyperosmolar, hyperglycemic state caused by the relative insulin deficiency.

Options A and B: An elevated serum acetone level and serum ketone bodies are characteristic of diabetic ketoacidosis.
Option C: Metabolic acidosis, not serum alkalosis, may occur in HHNS.

37
Q

For a client with Graves’ disease, which nursing intervention promotes comfort?

A. Restricting intake of oral fluids
B. Placing extra blankets on the client’s bed
C. Limiting intake of high-carbohydrate foods
D. Maintaining room temperature in the low-normal range

A

D. Maintaining room temperature in the low-normal range

Option D: Graves’ disease causes signs and symptoms of hypermetabolism, such as heat intolerance, diaphoresis, excessive thirst and appetite, and weight loss. To reduce heat intolerance and diaphoresis, the nurse should keep the client’s room temperature in the low-normal range.

Option A: To replace fluids lost via diaphoresis, the nurse should encourage, not restrict, intake of oral fluids.
Option B: Placing extra blankets on the bed of a client with heat intolerance would cause discomfort.
Option C: To provide needed energy and calories, the nurse should encourage the client to eat high-carbohydrate foods.

Q

Cleo is diagnosed with osteoporosis. Which electrolytes are involved in the development of this disorder?

A. Calcium and sodium
B. Calcium and phosphorous
C. Phosphorous and potassium
D. Potassium and sodium

A

B. Calcium and phosphorous

Option B: In osteoporosis, bones lose calcium and phosphate salts, becoming porous, brittle, and abnormally vulnerable to fracture.

Option D: Sodium and potassium aren’t involved in the development of osteoporosis.

Q

Johnny a firefighter was involved in extinguishing a house fire and is being treated to smoke inhalation. He develops severe hypoxia 48 hours after the incident, requiring intubation and mechanical ventilation. He most likely has developed which of the following conditions?

A. Adult respiratory distress syndrome (ARDS)
B. Atelectasis
C. Bronchitis
D. Pneumonia

A

A. Adult respiratory distress syndrome (ARDS)

Option A: Severe hypoxia after smoke inhalation is typically related to ARDS.

Options B, C, and D: The other conditions listed aren’t typically associated with smoke inhalation and severe hypoxia.

41
Q

A 67-year-old client develops acute shortness of breath and progressive hypoxia requiring right femur. The hypoxia was probably caused by which of the following conditions?

A. Asthma attack
B. Atelectasis
C. Bronchitis
D. Fat embolism

A

D. Fat embolism

Option D: Long bone fractures are correlated with fat emboli, which cause shortness of breath and hypoxia.

Options A and C: It’s unlikely the client has developed asthma or bronchitis without a previous history.
Option B: He could develop atelectasis but it typically doesn’t produce progressive hypoxia.

42
Q

A client with shortness of breath has decreased to absent breath sounds on the right side, from the apex to the base. Which of the following conditions would best explain this?

A. Acute asthma
B. Chronic bronchitis
C. Pneumonia
D. Spontaneous pneumothorax

A

D. Spontaneous pneumothorax

Option D: A spontaneous pneumothorax occurs when the client’s lung collapses, causing an acute decreased in the amount of functional lung used in oxygenation. The sudden collapse was the cause of his chest pain and shortness of breath.

Options A and B: An asthma attack would show wheezing breath sounds, and bronchitis would have rhonchi.
Option C: Pneumonia would have bronchial breath sounds over the area of consolidation.

43
Q

A 62-year-old male client was in a motor vehicle accident as an unrestrained driver. He’s now in the emergency department complaining of difficulty of breathing and chest pain. On auscultation of his lung field, no breath sounds are present in the upper lobe. This client may have which of the following conditions?

A. Bronchitis
B. Pneumonia
C. Pneumothorax
D. Tuberculosis (TB)

A

C. Pneumothorax

Options A, B, and D: From the trauma the client experienced, it’s unlikely he has bronchitis, pneumonia, or TB; rhonchi with bronchitis, bronchial breath sounds with TB would be heard.

44
Q

If a client requires a pneumonectomy, what fills the area of the thoracic cavity?

A. The space remains filled with air only
B. The surgeon fills the space with a gel
C. Serous fluids fills the space and consolidates the region
D. The tissue from the other lung grows over to the other side

A

C. Serous fluids fill the space and consolidate the region

Option C: Serous fluid fills the space and eventually consolidates, preventing extensive mediastinal shift of the heart and remaining lung.

Option A: Air can’t be left in the space.
Option B: There’s no gel that can be placed in the pleural space.
Option D: The tissue from the other lung can’t cross the mediastinum, although a temporary mediastinal shift exits until space is filled.

45
Q

Hemoptysis may be present in the client with a pulmonary embolism because of which of the following reasons?

A. Alveolar damage in the infarcted area
B. Involvement of major blood vessels in the occluded area
C. Loss of lung parenchyma
D. Loss of lung tissue

A

A. Alveolar damage in the infarcted area

Option A: The infarcted area produces alveolar damage that can lead to the production of bloody sputum, sometimes in massive amounts.

Option B: Clot formation usually occurs in the legs.
Options C and D: There’s a loss of lung parenchyma and subsequent scar tissue formation.

46
Q

Alvin with a massive pulmonary embolism will have an arterial blood gas analysis performed to determine the extent of hypoxia. The acid-base disorder that may be present is?

A. Metabolic acidosis
B. Metabolic alkalosis
C. Respiratory acidosis
D. Respiratory alkalosis

A

D. Respiratory alkalosis

Option D: A client with massive pulmonary embolism will have a large region and blow off large amount of carbon dioxide, which crosses the unaffected alveolar-capillary membrane more readily than does oxygen and results in respiratory alkalosis.

47
Q

After a motor vehicle accident, Armand a 22-year-old client is admitted with a pneumothorax. The surgeon inserts a chest tube and attaches it to a chest drainage system. Bubbling soon appears in the water seal chamber. Which of the following is the most likely cause of the bubbling?

A. Air leak
B. Adequate suction
C. Inadequate suction
D. Kinked chest tube

A

A. Air leak

Option A: Bubbling in the water seal chamber of a chest drainage system stems from an air leak. In pneumothorax, an air leak can occur as air is pulled from the pleural space.
Options B and C: Bubbling doesn’t normally occur with either adequate or inadequate suction or any preexisting bubbling in the water seal chamber.
