A client is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. The IV administration set delivers 10 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)

Given Information: Azithromycin dose: 500 mg Volume: 500 mL Infusion time: 2 hours Drop factor: 10 gtt/mL Calculate the total infusion time in minutes 2 hours x 60 min/hour = 120 minutes Calculate the total volume to be infused 500 mL Calculate the infusion rate in mL/min Infusion rate = Total volume / Infusion time Infusion rate = 500 mL / 120 min = 4.17 mL/min Calculate the gtt/min gtt/min = Infusion rate (mL/min) x Drop factor (gtt/mL) gtt/min = 4.17 mL/min x 10 gtt/mL = 41.7 gtt/min Round to the nearest whole number (as instructed) gtt/min = 42 gtt/min
