The healthcare provider prescribes cytovene 375 mg every 12 hours to infuse over 90 minutes. The pharmacy delivers cytovene 375 mg in a 150 mL IV bag. How many mL/hour should the nurse program the infusion pump? (Enter a whole number only.)

Calculation: Total volume = 150 mL. Total infusion time and convert to hours. Infusion time = 90 minutes = 90 minutes / 60 minutes/hour = 1.5 hours. Calculate the infusion rate in milliliters per hour (mL/hr). Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr) = 150 mL / 1.5 hr = 100 mL/hr.
