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.)

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)
