A nurse is preparing to administer bumetanide to a client who has heart failure. Which of the following findings indicates effectiveness of the medication?

A. Bumetanide is a loop diuretic used to reduce fluid overload in clients with heart failure. One of the key signs of fluid overload is pulmonary congestion, which manifests as crackles or rales on lung auscultation. Clear lung sounds after administration indicate effective diuresis and improvement in pulmonary status, reflecting the medication’s therapeutic effect. B. While normal bowel sounds are a sign of gastrointestinal function, they are not a direct indicator of bumetanide’s effectiveness. Loop diuretics primarily target fluid balance, not GI motility. C. A bounding pulse is not an expected effect of bumetanide and may indicate fluid volume overload or cardiovascular stress, which could suggest ineffective therapy rather than improvement. D. Being alert and oriented reflects neurological status, not the effectiveness of a diuretic. While maintaining mental status is important for overall patient safety, it is not a measure of fluid removal or improvement in heart failure symptoms.
