A client is receiving a secondary infusion of vancomycin 1,500 mg in 250 mL to be infused over two hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Calculation: Total volume = 250 mL. Total infusion time and convert to minutes. Infusion time = 2 hours = 2 hours x 60 minutes/hour = 120 minutes. Drip factor of the IV tubing = 15 gtt/mL. Calculate the infusion rate in drops per minute (gtt/min). Infusion rate (gtt/min) = (Total volume (mL) x Drip factor (gtt/mL)) / Total time (min) = (250 mL x 15 gtt/mL) / 120 min = 3750 gtt / 120 min = 31.25 gtt/min. Round to the nearest whole number = 31 gtt/min.
