A nurse is preparing to administer dextrose 5% in water 40 mL IV to infuse over 20 min to a child. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Step-by-Step Solution: Determine the total infusion time in hours. The infusion time is 20 minutes. There are 60 minutes in an hour. The infusion time in hours = 20 minutes / 60 minutes/hour = 0.3333 hours. Calculate the infusion rate in mL/hr. The total volume to be infused is 40 mL. The infusion time is 0.3333 hours. The infusion rate = 40 mL / 0.3333 hours = 120 mL/hr.
