Question 1 of 5
The physician gives orders to infuse 1 unit (250 mL) of packed red blood cells over 4 hours. Calculate the flow rate in milliliters per hour.
Correct Answer: A
Rationale:
To calculate the flow rate, divide the total volume (250 mL) by the total time (4 hours). 250 mL / 4 hours = 62.5 mL/hr. This is the correct answer (
A) because it gives the infusion rate in milliliters per hour as requested by the physician's order.
Choices B, C, and D are incorrect because they do not accurately reflect the flow rate based on the given parameters.
