    Calculation

    Begin intravenous infusion of heparin at 15 units/kg/hr using 25,000 units heparin in 250 mL D5W. The patient weighs 75 kg. Determine the initial intravenous rate of heparin in mL/hr. Do not provide the unit of measurement. Only provide the number. Round to one decimal place (tenths).

    mL/hr

    Explanation & Rationale

    Step 1: Calculate units/hr: 15 units/kg/hr × 75 kg = 1125 units/hr Step 2: Determine concentration: 25,000 units ÷ 250 mL = 100 units/mL Step 3: Calculate mL/hr: 1125 units/hr ÷ 100 units/mL = 11.25 → 11.3
