The healthcare provider prescribes regular insulin 10 units/hour IV. The pharmacy provides a solution of normal saline 250 mL with 125 units regular insulin. How many hours should the IV infuse? (Enter numeric value only. if rounding is required, round to the nearest whole number.)

Given: Total insulin in solution: 125 units Ordered infusion rate: 10 units/hour Step 1: Calculate the total infusion time: Total infusion time (hours) = Total insulin (units) / Infusion rate (units/hour) Total infusion time (hours) = 125 units / 10 units/hour Total infusion time (hours) = 12.5 hours Step 2: Round to the nearest whole number: Total infusion time (hours) ≈ 13 hours
