Hesi rn dosage calculation d441 ( 55 Questions)
A client is receiving a secondary infusion of vancomycin 1,500 mg in 250 ml to be infused over two hours. The intravenous (IV) administration set delivers 15 gtt/ml. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If sounding is required, round to the nearest whole number.)
Correct Answer: 31
Given Information:
Vancomycin dose: 1,500 mg
Volume: 250 mL
Infusion time: 2 hours
Drop factor: 15 gtt/mL
Calculate the total infusion time in minutes
2 hours x 60 min/hour = 120 minutes
Calculate the total volume to be infused
250 mL
Calculate the infusion rate in mL/min
Infusion rate = Total volume / Infusion time
Infusion rate = 250 mL / 120 min = 2.08 mL/min
Calculate the gtt/min
gtt/min = Infusion rate (mL/min) x Drop factor (gtt/mL)
gtt/min = 2.08 mL/min x 15 gtt/mL = 31.2 gtt/min
Round to the nearest whole number (as instructed)
gtt/min = 31 gtt/min
