Correct Answer is C
Explanation
The client is receiving an intravenous infusion of 1.5 L saline solution at a rate of 75 mL/hr. Since 1 L = 1000 mL, the total volume of the infusion is 1.5 L x 1000 mL/L = 1500 mL. At a rate of 75 mL/hr, it will take the client 1500 mL / 75 mL/hr = **15 hours** to finish the infusion.
A. 10 hours is not the correct answer because it does not account for the total volume of the infusion.
B. 7.5 hours is not the correct answer because it does not account for the total volume of the infusion.
d. 20 hours is not the correct answer because it does not account for the total volume of the infusion.
