Practice exercise (made-up values, not clinical guidance). A 57 kg patient has a fluid goal of 35 mL/kg/day and receives all fluid through a feeding tube. The formula is 76% free water and runs at 60 mL/h for 20 hours a day. The rest of the fluid is given as water flushes every 6 hours. What volume V is each flush? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 160 cm tall and weighs 117 kg. The practice protocol gives 13 kcal/kg of actual body weight per day if the BMI is 30–50 kg/m², and 22 kcal/kg of ideal body weight (Devine) per day if the BMI is above 50 kg/m². Find the energy goal E in kcal/day. Round to the nearest whole number.

GIR = mg/kg/min

Answer key

  1. 1. V = 300 mL
  2. 2. P = 91.2 g/day
  3. 3. V = 271 mL
  4. 4. R = 101 mL/h
  5. 5. E = 1521 kcal/day
  6. 6. GIR = 6.21 mg/kg/min
