A nurse is preparing to administer lactated Ringer's (LR) 1 liter IV to a school-age child to infuse over 24 hours. After calculating the hourly infusion rate, the nurse realizes that the infusion pump only displays rates in whole numbers. What is the most appropriate rate (in mL/hr) to set on the pump, and why?

Calculation: Identify the total volume and total time Total Volume: 1 liter (1,000 mL) Total Time: 24 hours Calculate the hourly infusion rate Hourly Rate (mL/hr) = Total Volume ÷ Total Time Hourly Rate = 1,000 ÷ 24 = 41.666... mL/hr Round to the nearest whole number Since the infusion pump only displays whole numbers and the decimal is 0.6, the rate is rounded up to the nearest whole integer. = 42 mL/hr
