Which statement about diuretics is true?

• A. They help reduce fluid overload by increasing urine production
• B. They increase fluid retention to maintain blood pressure
• C. They cure heart failure
• D. They are never used in combination with other heart failure medications

Answer: (A)

Diuretics promote diuresis, reducing fluid overload by increasing urine production. In heart failure, this helps lower circulating volume, which decreases preload and pulmonary/systemic edema, easing breathing and swelling. They’re used to relieve symptoms, not to cure heart failure, which is a chronic condition requiring ongoing therapy with multiple medications. Diuretics are often used in combination with other heart failure treatments (such as renin-angiotensin system blockers or beta-blockers), rather than being used alone or never with other meds. The idea that they would increase fluid retention to maintain blood pressure is opposite to their function, and they don’t cure heart failure, so those statements aren’t accurate.
