The nurse should monitor for which potential clinical manifestation after administering furosemide (Lasix)?

Choice A reason: Furosemide, a loop diuretic, reduces blood volume, often lowering blood pressure. Monitoring for hypotension is critical to prevent dizziness or shock, making this the correct manifestation to observe. Choice B reason: Decreased temperature is not a common effect of furosemide, which primarily affects fluid balance. Blood pressure changes are more relevant, so this is incorrect. Choice C reason: Furosemide may increase heart rate due to volume loss, not decrease pulse. Hypotension is a primary concern, making this incorrect for the expected manifestation. Choice D reason: Decreased respiratory rate is unrelated to furosemide, which may improve breathing in heart failure but not slow respiration. Blood pressure is key, so this is incorrect.
