Estimated blood volume (EBV) is commonly approximated as 70 mL per kilogram of body weight in pediatric patients. For a 20 kg child, which EBV value is closest?

• A. 1000 mL
• B. 900 mL
• C. 1400 mL
• D. 1800 mL

Answer: (C)

In pediatric patients, estimated blood volume is typically around 70 mL per kilogram of body weight. So for a 20 kg child, multiply: 20 × 70 = 1400 mL. That makes 1400 mL the closest value. The other options correspond to 50 mL/kg (1000 mL), 45 mL/kg (900 mL), and 90 mL/kg (1800 mL), which are not the standard pediatric estimate. EBV can vary with age and size, but 70 mL/kg is the common reference used in practice.
