Which electrolyte imbalance is a common concern in patients receiving loop diuretics?
- A. Hyperkalemia
- B. Hyponatremia
- C. Hypokalemia
- D. Hypercalcemia
Correct Answer: C
Rationale: The correct answer is Hypokalemia (Choice C). Loop diuretics can lead to potassium loss in the urine, resulting in hypokalemia. This electrolyte imbalance is a common concern with loop diuretic therapy and necessitates regular monitoring. Hyperkalemia (Choice A) is not typically associated with loop diuretics but with conditions like renal failure. Hyponatremia (Choice B) is more common with thiazide diuretics. Hypercalcemia (Choice D) is not a typical concern with loop diuretic use.

What is the primary purpose of administering insulin to a patient with diabetes?
- A. Regulate blood glucose levels
- B. Increase metabolism
- C. Prevent complications
- D. Promote insulin sensitivity
Correct Answer: A
Rationale: The correct answer is A: 'Regulate blood glucose levels.' Administering insulin to a patient with diabetes helps regulate blood glucose levels by facilitating the uptake of glucose into cells, thereby lowering high blood sugar levels. This process aims to prevent hyperglycemia and its associated complications. Choice B, 'Increase metabolism,' is incorrect as the primary role of insulin is not to increase metabolism directly. Choice C, 'Prevent complications,' is partially correct as regulating blood glucose through insulin administration does help prevent complications associated with uncontrolled diabetes, but it is not the primary purpose. Choice D, 'Promote insulin sensitivity,' is incorrect as insulin itself is administered to compensate for the lack of endogenous insulin in diabetic patients, rather than to promote sensitivity to it.
A nurse is caring for a client who is postoperative following a hip arthroplasty. Which of the following actions should the nurse take to prevent dislocation of the prosthesis?
- A. Place a pillow between the client's legs.
- B. Place the client in a high Fowler's position.
- C. Maintain the client in a side-lying position.
- D. Keep the client's legs elevated.
Correct Answer: A
Rationale: Placing a pillow between the client's legs is the correct action to prevent dislocation of the prosthesis after hip arthroplasty. This positioning helps maintain proper alignment and stability of the hip joint, reducing the risk of dislocation. Placing the client in a high Fowler's position (choice B) is not recommended after hip arthroplasty as it may strain the hip joint. Maintaining the client in a side-lying position (choice C) or keeping the client's legs elevated (choice D) does not provide the same level of support and alignment as placing a pillow between the legs.
A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?
- A. Glomerular filtration rate of 14 mL/min
- B. BUN 16 mg/dL
- C. Serum magnesium 1.8 mg/dL
- D. Serum phosphorus 4.0 mg/dL
Correct Answer: A
Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.
A client with preeclampsia and postpartum hemorrhage is being cared for by a nurse. The nurse should recognize that which of the following medications is contraindicated?
- A. Methylergonovine
- B. Misoprostol
- C. Dinoprostone
- D. Oxytocin
Correct Answer: A
Rationale: The correct answer is A, Methylergonovine. Methylergonovine is contraindicated in clients with preeclampsia due to the risk of hypertension. Misoprostol (choice B), Dinoprostone (choice C), and Oxytocin (choice D) are appropriate medications for managing postpartum hemorrhage and are not contraindicated in clients with preeclampsia.
A nurse is caring for a client who is receiving radiation therapy. Which of the following findings should the nurse expect?
- A. Weight gain
- B. Mouth sores
- C. Hyperpigmentation
- D. Increased saliva production
Correct Answer: B
Rationale: The correct answer is B: Mouth sores. Mouth sores are a common side effect of radiation therapy, especially when the treatment is focused on the head or neck area. Weight gain is not typically associated with radiation therapy; instead, clients may experience weight loss due to side effects like nausea and loss of appetite. Hyperpigmentation is not a common finding related to radiation therapy. Increased saliva production is not a typical side effect of radiation therapy; instead, clients may experience dry mouth.
