A nurse is preparing to start an IV infusion of lactated Ringer’s for a client who sustained a burn injury.
The client is prescribed 5,200 mL of fluid over the first 24 hr. How many mL/hr should the nurse set the pump to infuse for the first 8 hr? (Round the answer to the nearest whole number.
Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["325"]
Step 1 is to determine the total volume of fluid to be infused in the first 8 hours. According to the Parkland formula for fluid resuscitation, half of the prescribed volume is administered in the first 8 hours. Thus:
Total fluid for the first 8 hours = 5,200 mL ÷ 2 = 2,600 mL.
Step 2 is to calculate the infusion rate in mL/hr for the first 8 hours. Divide the total volume for the first 8 hours by the total time in hours:
Infusion rate = 2,600 mL ÷ 8 hr = 325 mL/hr.
Final calculated answer: 325 mL/hr.
