The nurse is caring for a client with a history of heart failure who is receiving furosemide (Lasix). Which of the following laboratory values should the nurse monitor?
Correct answer
A
Rationale
Furosemide, a loop diuretic, can cause hypokalemia, increasing the risk of arrhythmias in heart failure patients, so serum potassium must be monitored closely. Glucose (B), cholesterol (C), and hemoglobin (D) are not directly affected by furosemide.
