A patient has an order for 500 mL of NS to infuse over 8 hours. How many mL per hour should be set on the pump? Round to the nearest whole number.

Total Volume: 500 mL Total Time: 8 hours Calculate the infusion rate in milliliters per hour (mL/hr). Infusion rate (mL/hr) = Total volume (mL) / Total time (hr) = 500 mL / 8 hr = 62.5 mL/hr. Round the answer to the nearest whole number. = 63 mL/hr.
