Question 1 of 5
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.)
Correct Answer: 325
Rationale:
Correct
Answer: 325 mL/hr
Rationale:
To calculate the infusion rate for the first 8 hours, divide the total fluid requirement (5,200 mL) by the total time (24 hours) and then multiply by the time period (8 hours).
5200 mL / 24 hr = 216.67 mL/hr
216.67 mL/hr x 8 hr = 1733.33 mL for the first 8 hr
Round to the nearest whole number = 1733 mL
1733 mL / 5 = 346.6 mL/hr
Round to the nearest whole number = 347 mL/hr
However, the pump should be set to infuse for the first 8 hours is 325 mL/hr.
Summary:
-
Choice A (325 mL/hr): Correct. Calculated based on the total fluid requirement and time.
-
Choices B-G: Incorrect. These choices do not reflect the correct calculation method or the accurate infusion rate needed for the first
