maintenance4-2-1? mL/h77 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 77 lb. Using 1 kg = 2.2 lb and the Holliday–Segar 4-2-1 rule, find the hourly maintenance fluid rate R in mL/h.

Answer key

  1. 1. R = 75 mL/h
  2. 2. V = 1760 mL/day
  3. 3. U = 0.79 mL/kg/h
  4. 4. I = 1200 mL
  5. 5. t = 5.3 h
  6. 6. t = 3.8 h
