A nurse is providing teaching to a client who has heart failure and a new prescription for furosemide. Which of the following statements should the nurse make?

A. "Eat foods that are high in sodium.": Clients taking furosemide should limit sodium intake because high sodium can cause fluid retention, which worsens heart failure. Encouraging high-sodium foods would counteract the effects of the diuretic. B. "Taking furosemide can cause your potassium levels to be high.": Furosemide is a loop diuretic that increases potassium excretion, which can lead to hypokalemia, not hyperkalemia. Clients need to monitor for low potassium symptoms and may require potassium supplementation. C. "Taking furosemide can cause you to be overhydrated.": Furosemide promotes fluid loss through diuresis, so overhydration is unlikely; instead, clients are at risk for dehydration and electrolyte imbalances if fluid loss is excessive. D. "Rise slowly when getting out of bed.": Furosemide can cause orthostatic hypotension due to rapid fluid loss. Advising the client to rise slowly helps prevent dizziness or falls, making this an important safety teaching point.
