A patient with heart failure is prescribed furosemide (Lasix). Which of the following electrolyte imbalances should the nurse monitor for?
Correct answer
B
Rationale
Furosemide, a loop diuretic, increases potassium excretion, leading to hypokalemia, which can cause arrhythmias. Hyperkalemia, hypernatremia, and hyponatremia are less likely with furosemide.
