A patient needs 120 ml over 60 minutes with a drop factor of 15 gtt/ml. What is the gtt/min?

Explanation:
The main idea is calculating IV flow rate in drops per minute using the drop factor. You convert the desired volume into drops and then divide by the administration time. Multiply the volume by the drop factor: 120 mL × 15 gtt/mL = 1800 drops. Then divide by the time in minutes: 1800 drops ÷ 60 min = 30 gtt/min. So the infusion rate is 30 drops per minute. It helps to see it another way: the volume per minute is 120 mL ÷ 60 min = 2 mL/min. With a drop factor of 15 gtt/mL, 2 mL/min × 15 gtt/mL = 30 gtt/min. This aligns with the same result.
