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.)

Calculation: Total volume to be infused = 500 mL Infusion rate = 60 mL/hour Calculate the total infusion time in hours: Infusion time (hours) = Total volume (mL) / Infusion rate (mL/hour) = 500 mL / 60 mL/hour = 8.333 hours Round to the nearest tenth: = 8.3 hours
