Correct Answer: A

Rationale: The correct answer is hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss through increased urinary excretion, making hypokalemia the most concerning electrolyte imbalance. Hyponatremia (Choice B) is not typically associated with furosemide use. Hyperkalemia (Choice C) is less likely due to furosemide's potassium-wasting effect. Hypercalcemia (Choice D) is not a common electrolyte imbalance seen with furosemide.

Correct Answer: A

Rationale: Corrected Rationale: Daily weight monitoring is the most accurate way to assess fluid balance in patients receiving diuretics. Monitoring daily weight allows healthcare providers to track changes in fluid status more precisely. While monitoring intake and output (choice B) is essential, it may not provide a comprehensive picture of overall fluid balance. Monitoring blood pressure (choice C) is important but may not directly reflect fluid balance. Checking for edema (choice D) is useful but may not be as sensitive as daily weight monitoring in assessing fluid balance.

Correct Answer: C

Rationale: Applying sequential compression devices is the appropriate intervention for a client at risk for developing deep vein thrombosis (DVT). This intervention helps prevent venous stasis by promoting circulation in the lower extremities, reducing the risk of DVT. Massaging the client's legs every 4 hours is contraindicated as it can dislodge a blood clot and increase the risk of embolism. Administering prophylactic antibiotics is not indicated for preventing DVT. Encouraging the client to remain on bed rest can contribute to venous stasis and increase the risk of developing DVT.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid consuming alcohol while taking this medication.' Clients taking metformin should avoid alcohol as it increases the risk of lactic acidosis. Choice A is incorrect because metformin is usually taken with meals to reduce gastrointestinal side effects. Choice C is incorrect as metformin is typically taken with meals, not at bedtime. Choice D is incorrect because muscle pain is not a common side effect of metformin.

Correct Answer: C

Rationale: Yellow wound drainage can indicate infection, especially 36 hours postoperative, and should be reported to the provider promptly. Serosanguineous drainage is a normal finding in the early stages of wound healing, and a heart rate of 92/min and a blood pressure of 118/76 mm Hg are within normal ranges for a postoperative client. Therefore, the nurse should prioritize reporting the yellow wound drainage as it may require immediate intervention.
