1.5 kcal/mL68 g protein/L40 mL/h24 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 1.5 kcal/mL runs at 40 mL/h for 24 hours a day. How many kilocalories E does the patient receive per day?

2 kcal/mL1800 kcal/day? mL/h20 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 1800 kcal a day from a tube feed that provides 2 kcal/mL. The feed runs by pump for 20 hours a day. At what rate R do you set the pump, in mL/h? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A 56 kg patient needs 2 g of protein per kg a day. The tube feed contains 44 g of protein per litre and runs at 60 mL/h for 24 hours a day. How many grams of extra protein ΔP a day are still needed? Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). A critically ill man is 173 cm tall and weighs 172 kg. The practice protocol gives 2 g of protein per kg of ideal body weight (Devine) per day if the BMI is 30 to under 40 kg/m², and 2.5 g/kg of ideal body weight per day if the BMI is 40 kg/m² or more. Find the protein goal P in g/day. Round to the nearest whole number.

Answer key

  1. 1. E = 1440 kcal/day
  2. 2. R = 45 mL/h
  3. 3. ΔP = 48.6 g/day
  4. 4. R = 121 mL/h
  5. 5. GIR = 3.73 mg/kg/min
  6. 6. P = 172 g/day
