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.)

Given: Volume of fluid: 500 mL Infusion rate: 60 mL/hour Formula: Infusion time (hours) = Volume (mL) / Infusion rate (mL/hour) Step 1: Calculate the infusion time: Infusion time (hours) = 500 mL / 60 mL/hour Infusion time (hours) = 8.33 hours Step 2: Round to the nearest tenth: Infusion time (hours) ≈ 8.3 hours
