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). Count ice chips as half their volume.

Practice exercise (made-up values, not clinical guidance). A 500 mL bag runs by pump at 50 mL/h. At 19:30, 300 mL have already been infused. How many hours t until the bag is empty? Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). A 1000 mL infusion starts at 12:30 at 80 mL/h. After 4 hours the rate is changed to 50 mL/h and is not changed again. How many hours t after the start will the bag be empty? Round to one decimal place.

Answer key

  1. 1. V = 700 mL/day
  2. 2. V = 1760 mL/day
  3. 3. B = −575 mL
  4. 4. U = 2 mL/kg/h
  5. 5. t = 4 h
  6. 6. t = 17.6 h
