maintenance100-50-20? mL/day36 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 36 kg.

V = mL/day
2.Easy
maintenance4-2-1? mL/h9 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 9 kg.

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).

Practice exercise (made-up values, not clinical guidance). A 500 mL infusion starts at 08:30 at 80 mL/h. After 3 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.
