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. Lung sounds clear on auscultation: Clear lung sounds indicate that pulmonary congestion has decreased, reflecting effective diuresis from bumetanide. In heart failure, fluid accumulation in the lungs causes crackles or rales, so improvement in breath sounds demonstrates the medication is reducing fluid overload. B. Bounding radial pulse: A bounding pulse is not an expected effect of bumetanide and may indicate fluid shifts or other cardiovascular changes unrelated to diuresis. While monitoring pulse is important, a bounding pulse does not reflect the drug’s effectiveness in relieving heart failure symptoms. C. Alert and oriented to time, place, and person: Mental status may improve with correction of severe fluid overload or hypoxia, but being alert and oriented is not a direct measure of bumetanide’s effectiveness. Neurological status alone does not confirm diuretic action or fluid removal. D. Bowel sounds present in four quadrants on auscultation: Presence of bowel sounds indicates gastrointestinal function is intact but does not provide information about the resolution of heart failure symptoms. While important for overall assessment, it is not a measure of the effectiveness of diuretic therapy.
