Question 6
Regular
If an IV order says to infuse 1,000 mL of fluid at the rate of 125 mL/hr, how many hours will it take to complete the infusion?
Correct!
Incorrect
The correct answer is: A
Rationale
To infuse 1,000 mL at a rate of 125 mL/hr will take 8 hours.
Dividing the total volume by the infusion rate—1,000 mL ÷ 125 mL/hr—yields 8 hours. This calculation confirms the duration required for the complete infusion, aligning perfectly with standard practices for intravenous fluid administration.
B: 6 hours This duration would indicate a significantly higher infusion rate than prescribed, leading to potential complications in patient care.
C: 12 hours This time frame would suggest a slower infusion rate, which contradicts the specified rate of 125 mL/hr, resulting in an inaccurate completion time.
D: 10 hours This option also implies an incorrect infusion speed, as it does not accurately divide the total volume by the given rate.
E: 125 hours This duration drastically overestimates the time required, suggesting an unrealistic infusion rate that does not align with typical medical protocols.
