A nurse is preparing to administer lactated Ringer's 500 mL IV to infuse over 4 hr. 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.)

Determine the total volume to be administered: The client is to receive 500 mL of lactated Ringer's IV. Calculate the time to administer the volume: The medication is to be administered over 4 hours. Calculate the flow rate: To find the flow rate in mL/hr, we can divide the total volume by the time: Flow rate (mL/hr) = Total volume (mL) / Time (hr) Flow rate = 500 mL / 4 hr= 125 mL/hr
