1.Easy
maintenance4-2-1? mL/h22 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 22 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.

22 lb1 kg = 2.2 lb4-2-1
R = mL/h
2.Easy
maintenance100-50-20? mL/day32 kg

Practice exercise (made-up values, not clinical guidance). Use the Holliday–Segar 100-50-20 method to find the daily maintenance fluid volume V in mL/day for a child who weighs 32 kg.

Practice exercise (made-up values, not clinical guidance). The record shows a patient's intake and output for one 8-hour shift. The IV infusion ran at the rate shown for the whole shift. Find the fluid balance B = intake − output in mL (a negative answer means a net loss). Count ice chips as half their volume.

Practice exercise (made-up values, not clinical guidance). A 500 mL infusion starts at 18:30 at 120 mL/h. After 2 hours the rate is changed to 150 mL/h and is not changed again. How many hours t after the start will the bag be empty? Round to one decimal place.

Answer key

  1. 1. R = 40 mL/h
  2. 2. V = 1740 mL/day
  3. 3. B = −40 mL
  4. 4. B = 425 mL
  5. 5. V = 800 mL
  6. 6. t = 3.7 h
