The nurse mixes diphenhydramine 25 mg in a 100 mL bag of 0.9% sodium chloride, which is to be administered IV over 30 minutes. The IV pump should be set to administer how many mL/hour? (Enter numeric value only.)

Identify the total volume to be infused. Total volume = 100 mL Identify the infusion time in minutes. Infusion time = 30 minutes Convert the infusion time to hours. Infusion time (hours) = Infusion time (minutes) / 60 minutes/hour = 30 minutes / 60 minutes/hour = 0.5 hours Calculate the infusion rate in mL per hour. Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours) = 100 mL / 0.5 hours = 200 mL/hour
