Calculation
A nurse is preparing to administer lactated Ringer's 500 mL IV to infuse over 4 hr for a pregnant client who is dehydrated. 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.)
mL/hr
Explanation & Rationale
Identify the total volume and total infusion time. Total Volume: 500 mL Total Time: 4 hr Calculate the infusion rate in milliliters per hour (mL/hr). Infusion rate (mL/hr) = Total volume (mL) / Total time (hr) = 500 mL / 4 hr = 125 mL/hr.
