Question 1 of 5
Which of the following is a primary reason for the use of loop diuretics in chronic systolic heart failure?
Correct Answer: D
Rationale: The correct answer is D because loop diuretics act on the ascending loop of Henle to inhibit sodium and water reabsorption, promoting diuresis. This mechanism is independent of the glomerular filtration rate (GFR), making them effective even in low GFR situations common in heart failure. Explanation for other choices: A: Loop diuretics do not inhibit angiotensin II synthesis; this is the mechanism of ACE inhibitors. B: Loop diuretics do not increase venous return to the heart; this is the mechanism of drugs like nitrates. C: Loop diuretics do not inhibit renal prostaglandin biosynthesis; this is the mechanism of NSAIDs.
