1. A client with diabetes insipidus is being treated with desmopressin. The nurse should monitor for which of the following side effects?
- A. Hyponatremia
- B. Hypernatremia
- C. Hypokalemia
- D. Hypercalcemia
Correct answer: A
Rationale: The correct answer is A: Hyponatremia. Desmopressin, a medication used in diabetes insipidus, can cause water retention by increasing water reabsorption in the kidneys. This excess water retention can lead to dilutional hyponatremia, where sodium levels in the body become too low. Monitoring for hyponatremia is crucial to prevent complications such as neurological symptoms. Choices B, C, and D are incorrect because desmopressin is not known to cause hypernatremia, hypokalemia, or hypercalcemia.
2. A client with diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which laboratory value is most concerning?
- A. Serum potassium of 3.0 mEq/L
- B. Serum glucose of 200 mg/dl
- C. Serum pH of 7.30
- D. Serum sodium of 135 mEq/L
Correct answer: C
Rationale: In a client with Hyperosmolar Hyperglycemic State (HHS), a serum pH of 7.30 is the most concerning value as it indicates acidosis, a life-threatening condition that requires immediate intervention. Choices A, B, and D are not the most concerning in this scenario. A low serum potassium level (Choice A) may be expected due to cellular shift in hyperglycemia, a serum glucose level of 200 mg/dl (Choice B) is not as concerning compared to the extremely high initial glucose level, and a serum sodium level of 135 mEq/L (Choice D) is within the normal range and not the immediate priority.
3. In a male client with a history of hypertension diagnosed with primary hyperaldosteronism, the hypertension is caused by excessive hormone secretion from which of the following glands?
- A. Adrenal cortex
- B. Pancreas
- C. Adrenal medulla
- D. Parathyroid
Correct answer: A
Rationale: Primary hyperaldosteronism is characterized by excessive secretion of aldosterone from the adrenal cortex. Aldosterone, a hormone produced by the adrenal cortex, plays a crucial role in regulating blood pressure by promoting sodium and water retention in the kidneys. The adrenal medulla secretes catecholamines like epinephrine and norepinephrine, which are involved in the 'fight or flight' response, not in regulating blood pressure. The pancreas secretes insulin and glucagon, hormones involved in blood sugar regulation, not blood pressure. The parathyroid glands regulate calcium levels in the blood, not blood pressure.
4. The client delivered hours ago and has a boggy uterus displaced above and to the right of the umbilicus. What action should the nurse take?
- A. Inspect the perineal pad.
- B. Encourage voiding.
- C. Monitor vital signs.
- D. Notify the healthcare provider.
Correct answer: B
Rationale: A boggy uterus that is displaced above and to the right of the umbilicus may indicate a full bladder, which can impede uterine contraction and lead to hemorrhage. Encouraging the client to void helps relieve pressure on the uterus, promoting better contraction and preventing postpartum hemorrhage.
5. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which assessment finding is most concerning?
- A. Increased fatigue
- B. Elevated blood pressure
- C. Low urine output
- D. Elevated hemoglobin
Correct answer: B
Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, an elevated blood pressure is the most concerning assessment finding. Elevated blood pressure can indicate worsening hypertension, which requires immediate intervention. Increased fatigue may be expected due to anemia associated with CKD and erythropoietin therapy. Low urine output may indicate impaired kidney function but is not as immediately concerning as elevated blood pressure. Elevated hemoglobin levels are the desired outcome of erythropoietin therapy, indicating an appropriate response to treatment.
