A loop diuretic such as torsemide increases potassium excretion. To help prevent hypokalemia, the patient should be advised to increase intake of which foods?

• A. Bananas Only
• B. Salt Substitutes
• C. Bananas and Citrus Fruits
• D. Green Leafy Vegetables

Answer: (C)

Loop diuretics like torsemide cause the kidneys to excrete more potassium, which can lead to low potassium levels (hypokalemia). To offset this, you want a steady intake of potassium-rich foods so your body can maintain normal potassium balance. Bananas and citrus fruits are classic, easy-to-include potassium sources, making them a practical and effective choice to help prevent hypokalemia. While green leafy vegetables also provide potassium, the combination of bananas and citrus fruits covers two well-known, widely tolerated options, offering a simple way to boost potassium intake. Salt substitutes, though containing potassium, are not foods and can pose risks in certain patients, so they’re not the primary recommendation.
