Practice exercise (made-up values, not clinical guidance). A 61 kg patient needs 1.8 g of protein per kg a day. The tube feed contains 44 g of protein per litre and runs at 50 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). Over 24 hours a patient receives 1000 mL of parenteral nutrition with final concentrations of 17.5% dextrose and 4.25% amino acids, plus 250 mL of 10% lipid emulsion (1.1 kcal/mL). Find the non-protein kilocalorie to nitrogen ratio NPC : N (the number x in x : 1). Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 177 cm tall and weighs 147 kg. The practice protocol gives 11 kcal/kg of actual body weight per day if the BMI is 30–50 kg/m², and 25 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.

Answer key

  1. 1. E = 2200 kcal/day
  2. 2. E = 1800 kcal/day
  3. 3. ΔP = 57 g/day
  4. 4. R = 62 mL/h
  5. 5. NPC : N = 128
  6. 6. E = 1617 kcal/day
