The nurse is to calculate gtt/min to transfuse one unit 160 ml of platelets over one hour using blood tubing that has a drop factor of 15. How many gtt/min would you administer?

Calculation: Total Volume: 160 mL Infusion Time: 1 hour (60 minutes) Drop Factor: 15 gtt/mL Calculate the infusion rate in gtt/min Infusion Rate (gtt/min) = (Total Volume × Drop Factor) ÷ Time (min) Infusion Rate = (160 × 15) ÷ 60 Infusion Rate = 2,400 ÷ 60 Infusion Rate = 40 gtt/min
