maintenance4-2-1? mL/h38 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 38 kg.

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 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 1000 mL infusion starts at 14:00 at 150 mL/h. After 4 hours the rate is changed to 75 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 runs by pump at 50 mL/h. At 19:30, 450 mL have already been infused. How many hours t until the bag is empty? Round to one decimal place.

Answer key

  1. 1. R = 78 mL/h
  2. 2. R = 50 mL/h
  3. 3. B = −385 mL
  4. 4. B = 180 mL
  5. 5. t = 9.3 h
  6. 6. t = 11 h
