To infuse 100 mL of ampicillin over 30 minutes, what infusion rate should the nurse set?</n>

Explanation:
Infusion rate is found by dividing the volume to be given by the time over which it’s delivered. Here, 100 mL must be infused in 30 minutes. Convert to hours: 30 minutes is 0.5 hours. 100 mL ÷ 0.5 h = 200 mL per hour. Set the IV pump to 200 mL/h to deliver the dose over 30 minutes. If you used 100 mL/h, it would take 1 hour; 300 mL/h would finish in about 20 minutes; 50 mL/h would take 2 hours. Therefore, 200 mL/h is the correct rate.
