1.2 kcal/mL55 g protein/L100 mL/h18 h/dayP = ? g/day

Practice exercise (made-up values, not clinical guidance). A tube feed with 55 g of protein per litre runs at 100 mL/h for 18 hours a day. How many grams of protein P does the patient receive per day? Round to one decimal place.

Practice exercise (made-up values, not clinical guidance). A 77 kg patient has a fluid goal of 30 mL/kg/day and receives all fluid through a feeding tube. The formula is 84% free water and runs at 90 mL/h for 20 hours a day. The rest of the fluid is given as water flushes every 8 hours. What volume V is each flush? Round to the nearest whole number.

111 kg169 cmwomanBMI = kg/m²E = ? kcal/day

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 169 cm tall and weighs 111 kg. The practice protocol gives 14 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. P = 99 g/day
  2. 2. V = 200 mL
  3. 3. ΔP = 36 g/day
  4. 4. V = 266 mL
  5. 5. GIR = 5.76 mg/kg/min
  6. 6. E = 1554 kcal/day
