Practice exercise (made-up values, not clinical guidance). A patient needs 1500 kcal a day from a tube feed that provides 1.2 kcal/mL. The feed runs by pump for 24 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 92 kg patient needs 1.2 g of protein per kg a day. The tube feed contains 63 g of protein per litre and runs at 60 mL/h for 18 hours a day. A protein powder supplies 6 g of protein per scoop. How many scoops n a day are needed to cover the shortfall? Round up to a whole scoop.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 2000 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 non-protein energy NPC in kcal per day. Round to the nearest whole number.

  1. 1. V = 125 mL
  2. 2. R = 52 mL/h
  3. 3. R = 58 mL/h
  4. 4. n = 8
  5. 5. GIR = 3.41 mg/kg/min
  6. 6. NPC = 2360 kcal/day
