Which patient history element is most relevant for hypokalemia?

• A. Recent use of diuretics
• B. Family history of hypertension
• C. Excessive exercise
• D. Sedentary lifestyle

Answer: (D)

Potassium balance is governed by intake and renal losses, with hypokalemia arising when losses exceed what you’ve taken in or when potassium shifts into cells. Diuretics, especially loop and thiazide types, increase potassium excretion in the distal nephron, leading to a drop in serum potassium. That makes recent diuretic use the most relevant history element for hypokalemia. Sedentary lifestyle doesn’t directly affect potassium levels, and while excessive exercise can cause shifts in potassium, it isn’t a primary cause of chronic hypokalemia. A family history of hypertension doesn’t explain potassium status.
