A primary healthcare provider prescribes 30 mL/kg of 0.9% saline to a client weighing 236 pounds. How many mL should be infused?

• A. 3000 mL
• B. 3218 mL
• C. 3500 mL
• D. 3600 mL

Answer: (B)

The key idea is to convert the patient’s weight to kilograms and then apply the per-kilogram dose. Use a quick conversion: 1 kilogram ≈ 2.2 pounds. So the weight in kilograms is 236 ÷ 2.2 ≈ 107.27 kg. Multiply by the prescribed amount per kilogram: 107.27 kg × 30 mL/kg ≈ 3218 mL. Rounding to the nearest milliliter gives about 3218 mL, which is about 3.22 liters. This matches the option that aligns with the weight-based calculation using a 2.2 lb/kg conversion. If you used a more exact conversion (2.2046), you’d get a result slightly lower (around 3210 mL), but 3218 mL is the closest standard value for quick clinical dosing.
