A 15 kg child has 10% dehydration due to acute gastroenteritis. How much total fluid (in mL) should be administered in the first 24 hours (including maintenance and deficit replacement)?
- A 1750 mL
- B 2750 mL ✓
- C 3750 mL
- D 4500 mL
Correct answer: B. 2750 mL
Explanation
Deficit volume = 10% of body weight × 1000 mL/kg = 0.10 × 15 × 1000 = 1500 mL. Maintenance by Holliday-Segar: 1000 mL (first 10 kg) + 250 mL (5 kg × 50 mL/kg) = 1250 mL/day. Total 24-hour requirement = 1500 + 1250 = 2750 mL. Half the deficit (750 mL) is given in the first 8 hours along with one-third of maintenance, and the remaining deficit over the next 16 hours.
