A client is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. How many mL/hour should the nurse program the infusion pump? (Enter numerical value only.)

Calculation: Total volume to be infused = 500 mL Infusion time in hours = 2 hours Calculate the infusion rate in mL per hour: Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours) = 500 mL / 2 hours = 250 mL/hour
