Practice exercise (made-up values, not clinical guidance). A 500 mL infusion starts at 11:30 at 100 mL/h. After 3 hours the rate is changed to 80 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. R = 65 mL/h
  2. 2. R = 40 mL/h
  3. 3. U = 1.38 mL/kg/h
  4. 4. I = 1660 mL
  5. 5. V = 110 mL
  6. 6. t = 5.5 h
