Question

Quizplus · Accepted Answer

Bumetanide is a loop diuretic that works by blocking sodium reabsorption in the thick ascending limb of Henle's loop, which is located in the kidney. The term 'loop' refers to this specific location in the kidney where the medication acts. Option A is incorrect because bumetanide does not reabsorb potassium; it actually increases urinary excretion of potassium. Option B is incorrect because Bowman's capsule is part of the nephron but is not involved in loop diuretics. Option D is incorrect because bumetanide does not work in the proximal tubule, which is located before the loop of Henle.
