1 kcal/mL44 g protein/L70 mL/h18 h/dayE = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A tube feed that provides 1 kcal/mL runs at 70 mL/h for 18 hours a day. How many kilocalories E does the patient receive per day?

70 mL/h18 h/day1 kcal/mL
E = kcal/day
2.Easy
1 kcal/mL1600 kcal/day8 × ? mL8× per day

Practice exercise (made-up values, not clinical guidance). A patient on bolus tube feeding needs 1600 kcal a day from a formula that provides 1 kcal/mL. The daily amount is given as 8 equal boluses. What volume V is given in each bolus? Round to the nearest whole number.

84 g/L2 g/kg/day90 mL/h81 kg20 h/dayΔP = ? g

Practice exercise (made-up values, not clinical guidance). An 81 kg patient needs 2 g of protein per kg a day. The tube feed contains 84 g of protein per litre and runs at 90 mL/h for 20 hours a day. How many grams of extra protein ΔP a day are still needed? Round to one decimal place.

136 kg166 cmmanBMI = kg/m²P = ? g/day

Practice exercise (made-up values, not clinical guidance). A critically ill man is 166 cm tall and weighs 136 kg. The practice protocol gives 2 g of protein per kg of ideal body weight (Devine) per day if the BMI is 30 to under 40 kg/m², and 2.5 g/kg of ideal body weight per day if the BMI is 40 kg/m² or more. Find the protein goal P in g/day. Round to the nearest whole number.

Answer key

  1. 1. E = 1260 kcal/day
  2. 2. V = 200 mL
  3. 3. ΔP = 10.8 g/day
  4. 4. R = 179 mL/h
  5. 5. GIR = 4.27 mg/kg/min
  6. 6. P = 156 g/day
