Calculation
Find the total volume to administer. ___________. Ordered: D5W @ 20 gtt/min over 6 h via 60 gtt/ml tubing 120 mL
mL
Explanation & Rationale
Given values: Flow rate = 20 gtt/min Infusion time = 6 hours Drop factor = 60 gtt/mL Convert the infusion time from hours to minutes. Infusion time in minutes = 6 hours × 60 minutes/hour = 360 minutes. Calculate the total volume in milliliters (mL) using the formula: Total Volume (mL) = (Flow rate (gtt/min) × Infusion time (min)) / Drop factor (gtt/mL) = (20 gtt/min × 360 min) / 60 gtt/mL = 7200 / 60 = 120 mL.
