PTS: 1 MSC: IV Calculations
5. Directions: Determine the infusion time for the following IV. State time in both traditional
and military time. Round minutes to the nearest whole number of minutes.
150 mL D5W 1/2 NS infusing at 20 macrogtt/min. Drop factor: 15 gtt/mL.
Calculate the infusion time:
ANS:
15 gtt : 1 mL = 20 gtt : x mL
x = 1.33 = 1.3 mL/min
60 min 1.3 mL/min = 78 mL/hr
150 mL ÷ 78 mL/hr = 1.92 hr
60 min 0.92 hr = 55.2 = 55 min

Calculate the infusion time:
ANS:
10 gtt : 1 mL = 50 gtt : x mL
x = 5 mL/min
60 mL ÷ 5 mL/min = 12 min
Infusion time: 12 min
