Calculation
Find the flow rate for manual regulation: __________ (Round to the nearest whole number) Ordered: 1,800 mL RL q12h using tubing calibrated to 15 gtt/mL
gtt/min
Explanation & Rationale
Calculation: To find the flow rate in drops per minute (gtt/min), use the formula: Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Time (min) Total volume = 1,800 mL. Drop factor = 15 gtt/mL. Convert the total time from hours to minutes. Total time = 12 hours × 60 minutes/hour = 720 minutes. Calculate the flow rate. Flow rate = (1,800 mL × 15 gtt/mL) / 720 minutes = 27,000 gtt / 720 minutes = 37.5 gtt/min. Round the answer to the nearest whole number. = 38 gtt/min.
