Find the flow rate for manual regulation:__________. Ordered: 220 mL D5LR to infuse over 4 h using tubing calibrated to 60 gtt/mL

Calculation: Total volume = 220 mL. Drop factor = 60 gtt/mL. Convert the total time from hours to minutes. Total time = 4 hours × 60 minutes/hour = 240 minutes. Calculate the flow rate. Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Time (min) = (220 mL × 60 gtt/mL) / 240 minutes = 13200 gtt / 240 minutes = 55 gtt/min.
