Which description correctly identifies common heart failure therapy as described?

• A. A diuretic that ends in ide, such as furosemide or torsemide
• B. A thiazide diuretic only
• C. A potassium-sparing diuretic only
• D. A loop diuretic that ends in ace

Answer: (A)

Relieving fluid overload is a central goal in heart failure treatment, and loop diuretics are the most commonly used agents for this. They act quickly to promote diuresis, reducing preload and edema, which helps alleviate dyspnea and congestion. Drugs in this class typically end with the suffix -ide, with furosemide and torsemide as classic examples. That naming pattern matches the description given.

Thiazide diuretics can help, especially in combination therapy or for milder edema, but they aren’t the standard go-to for the main loop-driven relief of congestive symptoms in heart failure. Potassium-sparing diuretics are useful for potassium balance and may have mortality benefits, but they aren’t described as the primary, common diuretic therapy by themselves. And a loop diuretic ending in ace isn’t correct, since loop diuretics don’t end with -ace.

So the best description is a diuretic ending in -ide, reflecting the common loop diuretic therapy used in heart failure.
