Calculation
Find the flow rate in gtt/min. Ordered: 1,800 mL RL q24h using tubing calibrated to 10 gtt/mL
gtt/min
Explanation & Rationale
Total volume = 1,800 mL Infusion time = 24 hours Drop factor = 10 gtt/mL Convert the infusion time from hours to minutes. Infusion time in minutes = 24 hours × 60 minutes/hour = 1440 minutes. Calculate the flow rate in drops per minute (gtt/min) using the formula: Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Infusion time (min) = (1800 mL × 10 gtt/mL) / 1440 min = 18000 / 1440 = 12.5 gtt/min. Round the answer to the nearest whole number. = 13 gtt/min.
