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 10 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.)

To calculate the gtt/min, use the formula: gtt/min = (volume in mL x drop factor in gtt/mL) / time in min Plug in the given values: gtt/min = (250 mL x 10 gtt/mL) / 120 min Simplify and solve: gtt/min = 2500 gtt / 120 min = 20.83 gtt/min Round to the nearest whole number: gtt/min = 21 The nurse should regulate the infusion at 21 gtt/min
