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

• A 1500 mL/day
• B 1600 mL/day ✓
• C 1850 mL/day
• D 2000 mL/day

Explanation

The Holliday-Segar method gives 100 mL/kg/day for the first 10 kg, 50 mL/kg/day for the next 10 kg, and 20 mL/kg/day for each kg above 20 kg. For a 25 kg child: (100 × 10) + (50 × 10) + (20 × 5) = 1000 + 500 + 100 = 1600 mL/day. Option A (1500 mL) is the maintenance requirement for a 20 kg child (1000 + 500) and omits the extra 5 kg above 20.
