1.2 kcal/mL1200 kcal/day? mL/h16 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 1200 kcal a day from a tube feed that provides 1.2 kcal/mL. The feed runs by pump for 16 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 53 kg patient needs 2 g of protein per kg a day. The tube feed contains 63 g of protein per litre and runs at 70 mL/h for 16 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 man is 180 cm tall and weighs 91 kg. Find the actual weight as a percentage of the ideal body weight, %IBW, using the Devine formula (1 in = 2.54 cm). Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 1800 mL of parenteral nutrition with final concentrations of 10% dextrose and 3.5% amino acids, plus 250 mL of 10% lipid emulsion (1.1 kcal/mL). Find the non-protein energy NPC in kcal per day. Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 169 cm tall and weighs 101 kg. The practice protocol gives 13 kcal/kg of actual body weight per day if the BMI is 30–50 kg/m², and 23 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. R = 63 mL/h
  2. 2. E = 2800 kcal/day
  3. 3. ΔP = 35.4 g/day
  4. 4. %IBW = 121 %
  5. 5. NPC = 887 kcal/day
  6. 6. E = 1313 kcal/day
