Practice exercise (made-up values, not clinical guidance). A 1000 mL infusion starts at 11:30 at 75 mL/h. After 3 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.

Answer key

  1. 1. R = 65 mL/h
  2. 2. R = 61 mL/h
  3. 3. I = 1280 mL
  4. 4. U = 1.66 mL/kg/h
  5. 5. V = 340 mL
  6. 6. t = 10.8 h
