1 kcal/mL44 g protein/L45 mL/h24 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 1 kcal/mL runs at 45 mL/h for 24 hours a day. How many kilocalories E does the patient receive per day?

E = kcal/day
2.Easy
1.5 kcal/mL1800 mL/day5 × ? mL5× per day

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1800 mL of formula a day, given as 5 equal bolus feeds. What volume V is given in each bolus? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). An 87 kg adult (BMI below 30) needs 25 kcal/kg/day. The tube feed provides 1 kcal/mL and 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). An 80 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 85 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 2400 mL of parenteral nutrition with final concentrations of 17.5% dextrose and 6% 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 man is 190 cm tall and weighs 186 kg. The practice protocol gives 13 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 = 1080 kcal/day
  2. 2. V = 360 mL
  3. 3. R = 136 mL/h
  4. 4. ΔP = 54.2 g/day
  5. 5. NPC = 1703 kcal/day
  6. 6. E = 2101 kcal/day
