A nurse is caring for a client who is receiving furosemide to treat heart failure. Which of the following laboratory values should the nurse monitor for this client?.

Choice A rationale: Serum cholesterol is not directly affected by furosemide, a loop diuretic. Choice B rationale: Serum amylase is not directly affected by furosemide. Choice C rationale: Furosemide can cause hypokalemia (low potassium levels), so it’s important to monitor serum potassium levels in clients taking this medication. Normal serum potassium levels are 3.5-5.0 mEq/L. Choice D rationale: Serum triglyceride is not directly affected by furosemide.
