maintenance4-2-1? mL/h53 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 53 kg.

R = mL/h
2.Easy
maintenance4-2-1? mL/h33 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 33 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 patient weighs 90 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 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).

Practice exercise (made-up values, not clinical guidance). A 500 mL infusion starts at 19:30 at 120 mL/h. After 3 hours the rate is changed to 100 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 500 mL infusion starts at 13:00 at 150 mL/h. After 2 hours the rate is changed to 125 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 = 93 mL/h
  2. 2. R = 50 mL/h
  3. 3. U = 0.51 mL/kg/h
  4. 4. B = 690 mL
  5. 5. t = 4.4 h
  6. 6. t = 3.6 h
