Which diuretic is an example of thiazide diuretics?

• A. Chlorthalidone
• B. Lisinopril
• C. Amlodipine
• D. Furosemide

Answer: (A)

Thiazide diuretics lower blood pressure by blocking the Na-Cl symporter in the distal convoluted tubule, which decreases sodium reabsorption and promotes a mild, sustained diuresis. Chlorthalidone is a classic example of this class, which is why it’s the best choice. The other drugs listed are not thiazides: Lisinopril is an ACE inhibitor, Amlodipine is a calcium channel blocker, and Furosemide is a loop diuretic that acts in the thick ascending limb of the loop of Henle.
