A client is receiving a secondary intravenous (IV) infusion of azithromycin 500mg 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 rounding is required, round to the nearest whole number.)

Here's how to calculate the infusion rate (gtt/min) for the azithromycin administration: 1. We know: Total volume of solution (including azithromycin and normal saline): 500 mL (given) Infusion duration: 2 hours (given) IV administration set drip rate: 10 gtt/mL (given) 2. We need to find: Infusion rate (gtt/min) Steps: Calculate the total volume to be infused per hour: Volume per hour (mL) = Total volume (mL) / Infusion time (hours) Volume per hour (mL) = 500 mL / 2 hours Volume per hour (mL) = 250 mL/hour Calculate the infusion rate in gtt/min: Infusion rate (gtt/min) = Volume per hour (mL) x Drip rate (gtt/mL) / 60 minutes/hour (convert hour to minutes) Infusion rate (gtt/min) = 250 mL/hour x 10 gtt/mL / 60 minutes/hour Infusion rate (gtt/min) = 41.67 gtt/min (round to nearest whole number) Therefore, the nurse should regulate the infusion at approximately 42 gtt/min.
