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

• A. 1200 mL/day
• B. 1600 mL/day
• C. 1500 mL/day
• D. 1800 mL/day

Answer: (B)

The test relies on the Holliday-Segar method, which estimates daily maintenance fluids using weight-based tiers: 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 over 20. For a 25 kg child, calculate: 10 kg × 100 = 1000 mL, plus 10 kg × 50 = 500 mL, plus 5 kg × 20 = 100 mL. Total = 1600 mL/day. So the maintenance fluid requirement is 1600 mL per day.
