Question 20 :
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.)
Correct Answer: ["21 gtt\/min"]
To find the gtt/min, we need to multiply the mL/hour by the drop factor and divide by 60 minutes. The mL/hour is the volume of the infusion divided by the time of the infusion, which is 250 mL / 2 hours = 125 mL/hour. The drop factor is 10 gtt/mL. Therefore, the gtt/min is (125 mL/hour x 10 gtt/mL) / 60 minutes = 20.83 gtt/min. If rounding is required, we round to the nearest whole number, which is 21 gtt/min.
