Chapter 5,9,10 book info Flashcards
The nurse may call a rapid response team if they have an intuitive sense that something is going wrong with the patient or if the patient displays the following:
* An acute change in mental status
* Stridor
* Respirations less than 10 or greater than 32 breaths/min
* Increased effort to breathe
* Oxygen saturation less than 92%
* Pulse less than 55 or greater than 120 beats/min
* Systolic BP less than 90 or greater than 170mm Hg
* Temperature less than 35°C (95°F) or greater than 39.5°C
(103.1 °F)
* New onset of chest pain
* Agitation or restlessness
Females assigned at birth experience symptoms that are less specific and different from males assigned at birth.
Fever increases the metabolic rate.
Angina can be mistaken for indigestion or heartburn. It may also be felt in the shoulders, arms, neck, throat, jaw, or back.
Either a very fast or a very slow heart rate causes less blood to be circulated to the brain and body.
Pneumonia is an infection in the lungs that causes an inflammatory response and impaired ventilation and oxygenation of the body.
High BP reduces blood supply to the brain and vital organs because it cannot get through.
Low BP reduces the blood flow because the blood does not move forward into the brain and vital organs.
Heart disease, high BP, and chronic diseases increase as patients age. The prevalence of obesity does not differ significantly by race or ethnic group in men.
The symptoms of lung cancer are caused by the lung mass growing into healthy tissue and also taking nutrients away from other normal body functions.
The incidence of obesity has more than doubled since 1980 and an estimated two of three U.S. adults are overweight (American Association of Clinical Endocrinologists, 2016;
World Health Organization, 2020). Reduction of obesity is included in the goals for many developed nations.
chromosomes, prolonged sun exposure, and various genetic syndromes may contribute to premature aging.
Facial asymmetry may indicate Bell palsy or cerebrovascular ischemia. Obvious deformities may indicate fractures or displacements.
Poorly fitting clothes may indicate weight loss or gain. Bad breath can result from poor hygiene, allergic rhinitis, or infection (tonsilis, sinusitis. Sweet smelling breath may indicate diabetic ketoacidosis. Body odor may be from poor hygiene or increased sweat gland activity, which accompanies some hormonal disor-ders. Previously well-groomed patients who are now disheveled may be suffering from depression. Eccentric makeup or dress may indicate mania. Worn or disheveled clothes may indicate inadequate finances or knowledge.
Uncooperative behavior, flat affect, or unusual elation may indicate a psychiatric disorder (see Chapter 9). Note that mild anxiety is common in people seeking healthcare.
Barrel chest may indicate long-standing respiratory disease.
Pallor, erythema, cyanosis, jaundice, and lesions can indicate disease states
Delayed puberty may indicate a deficiency of growth hormones.
Altered growth hormones may lead to markedly short or tall stature. Disproportionate height and weight, obesity, or emaci-ation can indicate an eating disorder or hormonal dysfunction.
Inappropriate affect, inattentiveness, impaired memory, and inability to perform activities of daily living (ADLs) may indicate dementia (e.g, Alzheimer disease) or another cognitive disorder.
A flat or masklike expression may indicate Parkinson disease or depression. Drooping of one side of the face may indicate transient ischemic attack or cerebrovascular accident.
Exophthalmos (protruding eyes) may indicate hyperthyroidism.
Change in level of consciousness is often the first indication of hypoxia.
Confusion, agitation, drowsiness, or lethargy may indicate hy-poxia, decreased cerebral perfusion, or a psychiatric disorder.
Slow, slurred speech may indicate alcohol intoxication or cerebrovascular ischemia. Rapid speech may indicate hyper-thyroidism, anxiety, or mania. Difficulty finding words or using words inappropriately may indicate cerebrovascular ischemia or a psychiatric disorder. Loud speech may indicate hearing difficulties.
Slumped or hunched posture may indicate depression, fatigue, pain, or osteoporosis. Long limbs may indicate Marfan syn-drome. A tripod position when sitting can indicate respiratory disease (see Chapter 16). If the patient is in bed, note the position of the head of the bed or if the patient is lying on the left or right side.
Asymmetrical motion occurs in stroke; paralysis may accompany spinal cord injury. Limited range of motion might be present with injuries or degenerative disease.
Tics, paralysis, ataxia, tremors, or uncontrolled movements may indicate neurological disease.
Patients with Parkinson disease may display a shuffling gait. Arthritis may result in a slow, unsteady gait. For patients in bed, note their ability to move and reposition themselves in bed, turn side to side, and sit up.
Excessive unexplained weight loss may result from nutritional deficiencies, decreased intake, decreased absorption, increased metabolic needs, or a combination. Other causes may be endocrine, neoplastic, gastrointestinal, psychiatric, infectious, or neurological. Chronic disease also may contribute to weight loss.
Excessive weight gain occurs when a person consumes more calories than their body requires. Being overweight may result from endocrine disorders, genetics, or emotional factors such as stress anxiety, depression, or guilt. Drug therapy, especially steroids, may contribute to weight gain.
The patient with muscle weakness, scoliosis, or a neurological disorder may not be able to stand.
Chronic malnutrition may result in decrease height from lack of nutrients for proper growth. Decreased height also may result from osteoporosis. Hormonal abnormalities may cause excessive growth, as seen in gigantism and acromegaly, or deficiency in growth, as seen in dwarfism
The patient’s subjective report of feeling feverish is usually accurate. Take the patient’s temperature when they feel feverish or chilled.
The oral route should not be used to measure temperature in patients who are unconscious, orally intubated, or confused, or in those with a history of seizures. Taking oral temperatures is also contraindicated in cases of postoperative oral surgery or oral trauma. Oral thermometers are not recommended for children younger than 6 years.
Underweight is BMI <18.5; overweight is BMI of 25-29.9; obesity is BMI > 30; extreme obesity is BMI > 40. Obesity poses risks for disease
When the condition of the patient is stable, the nurse may delegate the tasks of obtaining anthropometric measurements and vital signs to nursing assistants. In such cases, nurses retain legal responsibility for assessing findings and intervening when necessary. Principles of delegation are used.
Rectal temperature measurement is contraindicated in new-borns, infants, and young children; patients who are neutro-penic; patients with rectal diseases; and those who have undergone rectal surgery. Patients with hemorrhoids and those with diarrhea should not have rectal temperatures as-sessed. The rectal route should also be avoided with patients who have cardiac conditions because insertion of the thermometer may cause vagal stimulation and reduce heart rate
Hypothermia is temperature <35°C (95°F). Prolonged exposure to cold may cause hypothermia. It may be induced purposefully during surgery to reduce the body’s oxygen demands. Hyperthermia, also known as pyrexia or fever, is body temperature exceeding 38.6°C (101.5°F) orally. It occurs during infections caused by bacteria, viruses, and fungi. Another cause is tissue breakdown, as seen in trauma, surgery, myocardial infarction, and malignancy. Low-grade fever may occur with conditions that cause inflammation, such as in autoimmune disorders. Certain neurological disorders, such as cerebrovascular accident, cerebral edema, tumor, or cerebral trauma, can affect the thermoregulation of the brain.
Fever above 39.5°C (103.1°F) in adults requires immediate assessment and rapid cooling measures. Monitor rectal temperature constantly during cooling measures to prevent a hypothermic response. Temperatures below 35°C (95°F) may require rewarming, according to established protocols.
Axillary temperature is the least accurate; so if discrepancies are noted, recheck the temperature using another route.
Errors in temperature measurements using a tympanic thermometer have been attributed to user error. Proper positioning of the probe may decrease the incidence of error.
Avoid placing the probe directly into stool, which may cause an inaccurate reading. The probe should be in contact with the rectal mucosa.
Studies have shown that the temporal artery measurement using the forehead and behind the ear method is more accurate than temporal artery measurements using the forehead alone and is comparable with the oral temperature
Tachycardia is a heart rate > 100 beats/min in an adult.
Trauma, anemia, blood loss, infection, fear, fever, pain, hyper-thyroidism, shock, and anxiety can increase pulse rate as a result of increased metabolic demands or low blood volume.
In patients with cardiac disease, tachycardia may indicate congestive heart failure, myocardial ischemia, or dysrhythmia.
Bradycardia is a heart rate <60 beats/min. Medications such as digoxin and beta-blockers decrease heart rate. Myocardial infarction, hypothyroidism, increased intracranial pressure, and eye surgery also can decrease heart rate.
Asystole is the absence of a pulse. Cardiac arrest, hypovolemia, pneumothorax, cardiac tamponade, and acidosis can cause asystole.
Rhythm may vary with respirations, speeding up during inspiration and slowing with expiration. This is common in children and young adults and is called a sinus dysrhythmia or sinus arrhythmia.
Heart failure, hypovolemia, shock, and arrhythmias can cause decreased pulse strength.
Pulse deficits are frequently associated with arrhythmias. It is essential to recognize a pulse deficit because it indicates the heart’s ability to perfuse the body adequately. When cardiac contractions do not produce enough force or volume to perfuse, a difference exists between apical and peripheral pulses.
Assess patients with dyspnea (difficulty breathing) in the position of greatest comfort to them. Repositioning may decrease the respiratory effort and promote improved oxygenation.
Bounding pulses are noted with early stages of septic shock, exercise, fever, and anxiety.
Pulsus alternans is a regular rhythm alternating with a strong and weak pulse; it indicates severe left ventricular failure.
Vessels become less elastic with increasing age.
The carotid pulse should be palpated only in the lower third of the neck to avoid stimulation of the carotid sinus. Never palpate both carotid pulses simultaneously. Palpating both at the same time can significantly decrease cerebral blood flow and cause the patient to lose consciousness.
Sudden changes in pulse rates or pulse rates > 120 or <55 beats/min may indicate life-threatening emergencies requiring immediate attention.
Counting the pulse for 30 seconds and doubling the result is more accurate than counting for 15 seconds and multiplying by 4.
If a peripheral pulse is diminished or absent, the tissue below may have an inadequate blood supply. This finding indicates the need for further assessment
Absent pulse indicates a need for further assessment. In combination with pain, pallor, or paresthesia, the viability of a limb may be threatened.
