1.Easy
maintenance4-2-1? mL/h55 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 55 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.

R = mL/h
2.Easy
maintenance4-2-1? mL/h27 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 27 kg.

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).

1000 mL80 mL/hstart 09:3016:30: ? mL

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 16:30?

1000 mL80 mL/h09:30 → 16:30
V = mL
6.Hard

Practice exercise (made-up values, not clinical guidance). A 500 mL bag was started at 11:30 and runs by pump at 60 mL/h. How many mL V are left in the bag at 15:00?

500 mL60 mL/h11:30 → 15:00
V = mL

Answer key

  1. 1. R = 65 mL/h
  2. 2. R = 67 mL/h
  3. 3. U = 0.72 mL/kg/h
  4. 4. B = 575 mL
  5. 5. V = 440 mL
  6. 6. V = 290 mL
