A child weighing 20 kg requires maintenance intravenous fluid therapy based on the Holliday-Segar formula. What is the total 24-hour maintenance fluid requirement?
Answer and explanation
Correct answer: C. 1500 mL per day
Answer: 1500 mL per day.
Why not the others: Holliday-Segar formula dictates 100 mL/kg for the first 10 kg (1000 mL) plus 50 mL/kg for the second 10 kg (500 mL), totaling 1500 mL/day (or 62.5 mL/h). 1000 mL covers only the initial 10 kg; 1200 mL represents inadequate maintenance volume; 2000 mL represents fluid overload for a 20-kg child.
