1.Easy
1 kcal/mL40 g protein/L80 mL/h18 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 1 kcal/mL runs at 80 mL/h for 18 hours a day. How many kilocalories E does the patient receive per day?

80 mL/h18 h/day1 kcal/mL
E = kcal/day
2.Easy
2 kcal/mL1200 mL/day5 × ? mL5× per day

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1200 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.

1200 mL/day5 boluses
V = mL
3.Medium
44 g/L1.8 g/kg/day85 mL/h77 kg18 h/dayΔP = ? g

Practice exercise (made-up values, not clinical guidance). A 77 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 18 hours a day. How many grams of extra protein ΔP a day are still needed? Round to one decimal place.

77 kg1.8 g/kg/day44 g/L85 mL/h · 18 h
ΔP = g/day
4.Medium
154 cmwomanIBW = ? kg

Practice exercise (made-up values, not clinical guidance). Use the Devine formula to find the ideal body weight IBW of a woman who is 154 cm tall (1 in = 2.54 cm). Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). Over 24 hours a patient receives 1800 mL of parenteral nutrition with final concentrations of 12.5% dextrose and 3.5% amino acids, plus 100 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.

GIR = mg/kg/min

Answer key

  1. 1. E = 1440 kcal/day
  2. 2. V = 240 mL
  3. 3. ΔP = 71.3 g/day
  4. 4. IBW = 46.9 kg
  5. 5. NPC : N = 96
  6. 6. GIR = 4.09 mg/kg/min
