maintenance4-2-1? mL/h11 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 11 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). Count ice chips as half their volume.

Practice exercise (made-up values, not clinical guidance). A 1000 mL infusion starts at 12:30 at 120 mL/h. After 2 hours the rate is changed to 60 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 = 20 mL/h
  2. 2. R = 58 mL/h
  3. 3. U = 2.42 mL/kg/h
  4. 4. B = −55 mL
  5. 5. V = 800 mL
  6. 6. t = 14.7 h
