What is the purpose of giving Slow-K potassium supplement to a patient on furosemide?

• A. To replace potassium losses produced by the furosemide
• B. To promote the effects of the diuretic
• C. To help facilitate nerve impulse conduction within the heart
• D. To prevent adverse effects produced by digoxin

Answer: (A)

Loop diuretics such as furosemide increase potassium excretion in the kidneys, which can lead to hypokalemia. Administering Slow-K provides potassium to replenish these losses and keeps serum potassium in the normal range, helping prevent muscle weakness, cramps, and potentially dangerous heart rhythms. It is not intended to enhance the diuretic effect or to directly improve nerve impulse conduction in the heart; maintaining potassium supports cardiac conduction, but the main purpose here is replacement of diuretic-related potassium loss. If digoxin is also involved, keeping potassium in the normal range can reduce digoxin toxicity, but that is an additional consideration rather than the primary purpose in this scenario.
