maintenance4-2-1? mL/h25 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 25 kg.

maintenance4-2-1? mL/h44 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 44 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 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 100 mL/h. After 4 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.

Practice exercise (made-up values, not clinical guidance). A 1000 mL infusion starts at 07:30 at 80 mL/h. After 2 hours the rate is changed to 50 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 = 65 mL/h
  2. 2. R = 60 mL/h
  3. 3. B = 1130 mL
  4. 4. U = 0.87 mL/kg/h
  5. 5. t = 4.7 h
  6. 6. t = 18.8 h
