A nurse is preparing to administer dextrose 5% in 0.45% sodium chloride 500 mL IV to infuse over 8 hr to a school-age child. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the infusion rate for the IV pump, divide the total volume of the IV fluid by the number of hours over which it is to be infused. In this case, 500 mL divided by 8 hours results in an infusion rate of 62.5 mL/hr. When rounding to the nearest whole number and not using a trailing zero, the IV pump should be set to deliver 63 mL/hr.
