RN Adult Medical Surgical 2023 Proctored Exam
Calculation
A nurse is preparing to infuse dextrose 5% in 0.45% sodium chloride 500 mL IV bolus over 4 hr. The drop factor of the manual IV tubing is 60 gtt/mL. The nurse should set the IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies, Do not use a trailing zero.)
gtt/min
Explanation & Rationale
Total Volume: 500 mL Infusion Time: 4 hours (240 minutes) Drop Factor: 60 gtt/mL Calculate the infusion rate in gtt/min Infusion Rate (gtt/min) = (Total Volume × Drop Factor) ÷ Time (min) Infusion Rate = (500 × 60) ÷ 240 Infusion Rate = 30,000 ÷ 240 Infusion Rate = 125 gtt/min Round to the nearest whole number = 125 gtt/min
