maintenance100-50-20? mL/day44 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 44 kg.

V = mL/day
2.Easy
maintenance4-2-1? mL/h77 lb

Practice exercise (made-up values, not clinical guidance). A child weighs 77 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). A 500 mL infusion starts at 15:00 at 80 mL/h. After 3 hours the rate is changed to 200 mL/h and is not changed again. How many hours t after the start will the bag be empty? Round to one decimal place.
