A client receives a prescription for cefazolin 1 gram in 200 mL of 0.9% normal saline to infuse over 30 minutes. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only.)

Formula: Infusion rate (mL/hour) = Total volume (mL) / Total time (hours) Total volume: Total volume = 200 mL Convert infusion time from minutes to hours: 1 hour = 60 minutes 30 minutes = 30 minutes / 60 minutes/hour = 0.5 hours Total infusion time = 0.5 hours Calculate the infusion rate in mL/hour: Infusion rate (mL/hour) = Total volume (mL) / Total time (hours) = 200 mL / 0.5 hours = 400 mL/hour
