A nurse is caring for a client who is receiving an intravenous infusion via pump at a rate of 3 mL/min. The infusion started 2 hr ago with 500 mL in the medication bag. How many ml have been infused?
Correct answer
C
Rationale
The correct answer is C (360 mL). To calculate the amount infused, multiply the infusion rate (3 mL/min) by the total time (2 hours x 60 min/hour = 120 min). 3 mL/min x 120 min = 360 mL. Choice A (180 mL) is incorrect because it does not account for the full 2 hours of infusion. Choice B (157 mL) is incorrect as it is too low for a 2-hour infusion at 3 mL/min. Choice D (334 mL) is incorrect as it is also too low for a 2-hour infusion at 3 mL/min.
