Practice exercise (made-up values, not clinical guidance). A man is 181 cm tall and weighs 99 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 1000 mL of parenteral nutrition with final concentrations of 20% dextrose and 5% amino acids, plus 100 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.

Practice exercise (made-up values, not clinical guidance). A critically ill man is 185 cm tall and weighs 116 kg. The practice protocol gives 14 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. E = 1200 kcal/day
  2. 2. R = 60 mL/h
  3. 3. %IBW = 130 %
  4. 4. R = 142 mL/h
  5. 5. E = 1080 kcal/day
  6. 6. E = 1624 kcal/day
