maintenance100-50-20? mL/day46 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 46 kg.

V = mL/day
2.Easy
maintenance4-2-1? mL/h66 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 66 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 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.

500 mL→ 60 mL/hstart 12:30ttotal​ = ? h100 mL/h × 2 h

Practice exercise (made-up values, not clinical guidance). A 500 mL infusion starts at 12:30 at 100 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.

Practice exercise (made-up values, not clinical guidance). A 1000 mL bag was started at 09:30 and runs by pump at 80 mL/h. How many mL V are left in the bag at 16:00?

V = mL

Answer key

  1. 1. V = 2020 mL/day
  2. 2. R = 70 mL/h
  3. 3. I = 1710 mL
  4. 4. B = 220 mL
  5. 5. t = 7 h
  6. 6. V = 480 mL
