A client is receiving a secondary intravenous (IV) infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. The IV administration set delivers 20 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 infusion rate, we need to use the formula: Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min) Plugging in the given values, we get: Infusion rate (gtt/min) = 500 mL x 20 gtt/mL / 120 min Simplifying, we get: Infusion rate (gtt/min) = 10000 gtt / 120 min Dividing both sides by 120, we get: Infusion rate (gtt/min) = 83.33 gtt/min Rounding to the nearest whole number, we get: Infusion rate (gtt/min) = 83 gtt/min
