Using the Holliday-Segar method, what is the daily maintenance fluid requirement for a 25 kg child?

• A 1600 mL/day ✓
• B 1500 mL/day
• C 1700 mL/day
• D 2500 mL/day

Explanation

The Holliday-Segar method: 100 mL/kg for the first 10 kg = 1000 mL; 50 mL/kg for the next 10 kg = 500 mL; 20 mL/kg for each kilogram above 20 kg — here 5 kg × 20 = 100 mL. Total = 1000 + 500 + 100 = 1600 mL/day. The common error is using 1500 mL (forgetting the last 5 kg contribution) or 1700 mL (adding 20 mL/kg for all 15 kg above 10 kg instead of only 5 kg above 20 kg).
