Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 2400 mL of parenteral nutrition with final concentrations of 20% dextrose and 4% amino acids, plus 500 mL of 20% lipid emulsion (2 kcal/mL). Find the total energy E the patient receives in kcal per day. Round to the nearest whole number.

Answer key

  1. 1. E = 990 kcal/day
  2. 2. P = 77 g/day
  3. 3. ΔP = 39.2 g/day
  4. 4. ΔP = 44.1 g/day
  5. 5. GIR = 3.85 mg/kg/min
  6. 6. E = 3016 kcal/day
