Which diuretic class is incorrectly matched with its indication?

• A. Loop diuretics: Pulmonary Edema
• B. K+ Sparing Diuretics: Nephrolithiasis
• C. Carbonic Anhydrase Inhibitors: Open Angle Glaucoma
• D. Osmotic Diuretic: Cerebral Edema

Answer: (B)

Diuretic classes have specific indications based on how they alter fluid and electrolyte handling in the kidney. Loop diuretics quickly reduce fluid overload, so they’re a good choice for pulmonary edema. Carbonic anhydrase inhibitors decrease aqueous humor production, which helps in open-angle glaucoma. Osmotic diuretics draw water into the bloodstream to reduce brain swelling, making them useful for cerebral edema. Potassium-sparing diuretics conserve potassium and are used to counteract potassium loss with other diuretics or in conditions like hyperaldosteronism; they’re not the go-to for preventing kidney stones. For nephrolithiasis, especially calcium-containing stones, thiazide diuretics are preferred because they reduce urinary calcium excretion. So the mismatched pair is potassium-sparing diuretics with nephrolithiasis.
