A nurse is assessing a client who is taking furosemide to treat heart failure. Which of the following findings should indicate to the nurse that the medication is having a therapeutic effect?

A. Decreased blood pressure: While furosemide can lower blood pressure due to fluid loss, the primary therapeutic goal in heart failure is the reduction of fluid overload and improvement in symptoms of congestion, not just lowering BP. B. Distended neck veins: Jugular vein distention indicates fluid retention and right-sided heart failure, suggesting the medication is not achieving its intended diuretic effect. C. Weight loss: Furosemide promotes diuresis, reducing excess fluid and relieving edema. Weight loss reflects decreased fluid retention and is a key indicator of therapeutic effectiveness in managing heart failure. D. Increased heart rate: A rising heart rate may signal worsening heart failure or dehydration from over-diuresis, both of which indicate that the medication is not being tolerated or is not properly balanced.
