Question 1 of 5
How many mL/h should the nurse set the IV infusion pump to deliver half the total volume of lactated Ringer's (4,080 mL) in the first 8 hours?
Correct Answer: D
Rationale: The correct answer is D: 255 mL/h.
To deliver half of 4,080 mL in 8 hours, you need to administer 2,040 mL in 8 hours.
To calculate the infusion rate, divide the total volume by the total time: 2,040 mL รท 8 hours = 255 mL/h. This rate ensures half of the total volume is infused within the specified time frame.
Choice A (200 mL/h) is too slow, as it would not deliver half the volume in 8 hours.
Choices B, C, and E exceed the required rate and would deliver more than half the volume in 8 hours.
