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.

R = mL/h
2.Easy
maintenance4-2-1? mL/h6 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 6 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 total intake I in mL.

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 1000 mL infusion starts at 16:00 at 80 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.

t = h

Answer key

  1. 1. R = 40 mL/h
  2. 2. R = 24 mL/h
  3. 3. I = 1680 mL
  4. 4. B = 955 mL
  5. 5. V = 820 mL
  6. 6. t = 6.8 h
