• A. 10 units
• B. 11 units
• C. 12 units
• D. 13 units

Answer: (C)

We convert weight to kilograms because the dose is given per kilogram. Using 1 kg ≈ 2.205 lb, 256 lb ≈ 256 ÷ 2.205 ≈ 116 kg. Multiply by 0.1 units/kg: 0.1 × 116 ≈ 11.6 units. Rounding to the nearest whole unit gives 12 units. So the bolus dose is about 12 units.
