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.)

Total volume in mL x Drop factor) / Total time in minutes. For the vancomycin infusion, the total volume is 250 mL, the drop factor is 15 gtt/mL, and the total time is 120 minutes (2 hours). The calculation is as follows: (250 mL x 15 gtt/mL) / 120 minutes = 31.25 gtt/min. After rounding to the nearest whole number, the nurse should regulate the infusion to 31 gtt/min.
