maintenance4-2-1? mL/h49 kg

Practice exercise (made-up values, not clinical guidance). Use the Holliday–Segar 4-2-1 rule to find the hourly maintenance fluid rate R in mL/h for a child who weighs 49 kg.

R = mL/h
2.Easy
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.

Practice exercise (made-up values, not clinical guidance). The record shows a patient's intake and output for one 12-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).

Practice exercise (made-up values, not clinical guidance). A 500 mL infusion starts at 11:00 at 75 mL/h. After 3 hours the rate is changed to 200 mL/h and is not changed again. How many hours t after the start will the bag be empty? Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). A 1000 mL bag was started at 12:45 and runs by pump at 100 mL/h. How many mL V are left in the bag at 19:45?

1000 mL100 mL/h12:45 → 19:45
V = mL

Answer key

  1. 1. R = 89 mL/h
  2. 2. R = 75 mL/h
  3. 3. B = 40 mL
  4. 4. U = 1 mL/kg/h
  5. 5. t = 4.4 h
  6. 6. V = 300 mL
