maintenance4-2-1? mL/h88 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 88 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.

Practice exercise (made-up values, not clinical guidance). A 500 mL infusion starts at 13:00 at 120 mL/h. After 3 hours the rate is changed to 125 mL/h and is not changed again. How many hours t after the start will the bag be empty? Round to one decimal place.

t = h

Answer key

  1. 1. R = 20 mL/h
  2. 2. R = 80 mL/h
  3. 3. U = 1.47 mL/kg/h
  4. 4. U = 1.7 mL/kg/h
  5. 5. V = 425 mL
  6. 6. t = 4.1 h
