A 74-year-old man with a history of heart failure is admitted to the coronary care unit with acute pulmonary edema
He's intubated and placed on a ventilator. Which of the following parameters should the nurse closely monitor in assessing the patient's response to a bolus dose of IV furosemide (Lasix)?
A) Daily weight
B) 24-hour intake and output
C) Serum sodium levels
D) Hourly urine output
Ans: D
Feedback: Furosemide administered by IV bolus takes effect almost immediately (within 5 minutes) and an increase in urine output will be noted (except in cases of renal failure). Daily weight, 24-hour intake and output, and serum sodium levels would span repeated doses of furosemide, making them less valuable in monitoring the patient's initial reaction to the drug.
