Question 1 of 5
A client is ordered to receive a bolus of 200 mL of NSS in 25 minutes. At what rate should the nurse set the IV pump?
Correct Answer: A
Rationale: The correct rate is 480 mL/hr.
To calculate this, divide the total volume (200 mL) by the total time (25 minutes), then convert the time to hours (25 minutes ÷ 60 = 0.42 hours). Next, divide the volume by the time (200 mL ÷ 0.42 hours = 476.19 mL/hr), which is rounded up to 480 mL/hr. This rate ensures the client receives the prescribed 200 mL of NSS in 25 minutes.
Choice A is correct because it accurately calculates the infusion rate based on the given parameters. Other choices are incorrect as they do not provide the precise calculation needed for the correct rate.
