Which parameter should a nurse monitor in a client taking furosemide (Lasix)?

• A. Blood pressure
• B. Respiratory rate
• C. Pulse oximetry
• D. Babinski reflex

Answer: (A)

Loop diuretics like furosemide cause rapid fluid loss, which can lower intravascular volume and lead to hypotension. The most important parameter to monitor is blood pressure because a drop in BP signals volume depletion and potential risk of dizziness, fainting, or reduced organ perfusion. While monitoring weight, intake/output, and electrolytes (especially potassium) is also important in management, blood pressure directly reflects the immediate safety concern with furosemide therapy. Respiratory rate and pulse oximetry aren’t the primary concerns for this drug unless there’s a specific respiratory issue, and the Babinski reflex is not related to diuretic effects.
