maintenance100-50-20? mL/day27 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 27 kg.

V = mL/day
2.Easy
maintenance4-2-1? mL/h47 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 47 kg.

Practice exercise (made-up values, not clinical guidance). The record shows a patient's intake and output for one 12-hour shift. The patient weighs 70 kg. Find the average urine output U in mL/kg/h. Round to two decimal places.

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 10:00 at 150 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.

V = mL

Answer key

  1. 1. V = 1640 mL/day
  2. 2. R = 87 mL/h
  3. 3. U = 1.64 mL/kg/h
  4. 4. B = 605 mL
  5. 5. t = 13.7 h
  6. 6. V = 600 mL
