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 06:30 at 80 mL/h. After 4 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 1000 mL bag was started at 13:00 and runs by pump at 125 mL/h. How many mL V are left in the bag at 17:00?

1000 mL125 mL/h13:00 → 17:00
V = mL

Answer key

  1. 1. R = 46 mL/h
  2. 2. R = 28 mL/h
  3. 3. U = 1.36 mL/kg/h
  4. 4. B = 525 mL
  5. 5. t = 5.8 h
  6. 6. V = 500 mL
