1.5 kcal/mL2100 kcal/day? mL/h20 h/day

Practice exercise (made-up values, not clinical guidance). A patient needs 2100 kcal a day from a tube feed that provides 1.5 kcal/mL. The feed runs by pump for 20 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 man is 178 cm tall and weighs 88 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 2400 mL of parenteral nutrition with final concentrations of 17.5% dextrose and 6% amino acids, plus 250 mL of 20% lipid emulsion (2 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 man is 184 cm tall and weighs 129 kg. The practice protocol gives 13 kcal/kg of actual body weight per day if the BMI is 30–50 kg/m², and 24 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 = 70 mL/h
  2. 2. R = 42 mL/h
  3. 3. %IBW = 120 %
  4. 4. IBW = 62.3 kg
  5. 5. NPC : N = 84
  6. 6. E = 1677 kcal/day
