Question 12 :
The nurse is initiating a 500 mL IV of normal saline at 60 mL/hour for a client with heart failure. How many hours should the IV infuse? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: ["8.3 hours"]
To find out how many hours the IV should infuse, you need to use the formula: V/T = R, where V is the volume of fluid, T is the time of infusion, and R is the rate of infusion. In this case, V = 500 mL, T is unknown, and R = 60 mL/hour. Plug in the values and solve for T:
T = V / R
T = 500 mL / 60 mL/hour
T = 8.33 hours
Therefore, the IV should infuse for 8.33 hours.
= 8.3 hours (rounded off to the nearest tenth)
