1. A patient is admitted to the hospital with a diagnosis of primary hyperparathyroidism. A nurse checking the patient's lab results would expect which of the following changes in laboratory findings?
- A. Elevated serum calcium
- B. Low serum parathyroid hormone (PTH)
- C. Elevated serum vitamin D
- D. Low urine calcium
Correct answer: A
Rationale: In primary hyperparathyroidism, there is excess secretion of parathyroid hormone (PTH) leading to increased resorption of calcium from bones and decreased excretion of calcium by the kidneys. This results in elevated serum calcium levels. Elevated serum calcium is a hallmark characteristic of primary hyperparathyroidism, making it the correct answer. Low serum parathyroid hormone (PTH) (Choice B) is incorrect because primary hyperparathyroidism is associated with elevated PTH levels due to the malfunction of the parathyroid glands. Elevated serum vitamin D (Choice C) is incorrect because primary hyperparathyroidism is not typically associated with elevated vitamin D levels. Low urine calcium (Choice D) is incorrect as primary hyperparathyroidism leads to decreased calcium excretion by the kidneys, resulting in high levels of calcium in the urine.
2. Which of the following is NOT a warning sign that compensatory mechanisms in a patient in shock are failing?
- A. Increasing heart rate above normal for the patient's age.
- B. Absent peripheral pulses
- C. Decreasing level of consciousness
- D. Increasing blood pressure
Correct answer: D
Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.
3. A pregnant woman who is 36 weeks' pregnant and has hepatitis B is being informed by a nurse. Which of the following statements from the client indicates understanding of this condition?
- A. Now I know my baby will need a cesarean section.
- B. My baby will need two shots soon after birth.
- C. I will not be able to breastfeed.
- D. My baby's father does not need testing; I know I am the one with hepatitis.
Correct answer: B
Rationale: The correct answer is 'My baby will need two shots soon after birth.' A baby born to a mother with hepatitis B should receive two injections soon after birth to reduce the risk of contracting the disease. Within the first 12 hours post-birth, the baby should receive the first hepatitis B vaccine and hepatitis B immune globulin (HBIG) for additional protection. Option A is incorrect because the need for a cesarean section is not directly related to the mother's hepatitis B status. Option C is incorrect as breastfeeding can be safe if managed properly. Option D is incorrect as the baby's father should also be tested for hepatitis B to prevent transmission to the newborn.
4. A patient admitted to the hospital with myocardial infarction develops severe pulmonary edema. Which of the following symptoms should the nurse expect the patient to exhibit?
- A. Slow, deep respirations
- B. Stridor
- C. Bradycardia
- D. Air hunger
Correct answer: D
Rationale: In a patient with pulmonary edema following a myocardial infarction, the nurse should expect symptoms such as air hunger, anxiety, and agitation. Air hunger refers to the feeling of needing to breathe more deeply or more often. Other symptoms of pulmonary edema can include coughing up blood or bloody froth, orthopnea (difficulty breathing when lying down), and paroxysmal nocturnal dyspnea (sudden awakening with shortness of breath). Slow, deep respirations (Choice A) are not typical in pulmonary edema; these patients often exhibit rapid, shallow breathing due to the difficulty in oxygen exchange. Stridor (Choice B) is a high-pitched breathing sound often associated with upper airway obstruction, not typically seen in pulmonary edema. Bradycardia (Choice C), a slow heart rate, is not a characteristic symptom of pulmonary edema, which is more likely to be associated with tachycardia due to the body's compensatory response to hypoxia and increased workload on the heart.
5. When reading a lab report, you notice that a patient's sample is described as having anisocytosis. Which of the following most accurately describes the patient's condition?
- A. The patient has an abnormal condition of skin cells.
- B. The patient's red blood cells vary in size.
- C. The patient has a high level of fat cells and is obese.
- D. The patient's cells are indicative of necrosis.
Correct answer: B
Rationale: Anisocytosis is a term that indicates variation in the size of red blood cells. When a patient is described as having anisocytosis, it means their red blood cells exhibit differences in size. This condition can be detected in blood samples and may indicate underlying blood disorders. The other choices are incorrect: Choice A refers to a skin cell condition, Choice C relates to obesity and fat cells, and Choice D suggests necrosis, none of which are associated with anisocytosis or red blood cell abnormalities. It is important to recognize specific terms like anisocytosis in laboratory reports to understand the potential implications for the patient's health.
