Extract:


Question 1 of 5

A nurse is preparing to administer 0.9% sodium chloride (NS) 2000 mL IV to infuse over 8 hr. 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.)

Correct Answer: B

Rationale: The correct answer is B (250 mL/hr).
To calculate the IV pump rate, divide the total volume to be infused (2000 mL) by the total time in hours (8 hr). 2000 mL รท 8 hr = 250 mL/hr. This rate ensures the 0.9% NS is infused at the prescribed rate over 8 hours.
Choice A (200 mL/hr) is incorrect because it would infuse the solution too slowly.

Choices C (300 mL/hr) and D (350 mL/hr) are incorrect as they would infuse the solution too quickly, potentially causing fluid overload or adverse effects.
