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

The nurse should set the infusion pump to deliver the entire 150 mL over the course of 90 minutes. First, convert the time from minutes to hours because the rate is required in mL/hr. 90 minutes is 1.5 hours (since 1 hour = 60 minutes). Therefore, the IV pump should be set to deliver: Rate (mL/hr)=Time (hr)Total volume (mL)​=1.5 hr150 mL​ After performing the calculation, we find that the rate equals 100 mL/hr. So, the nurse should set the infusion pump to deliver 100 mL/hr. This is rounded to the nearest whole number as per the instructions.
