1 kcal/mL40 g protein/L80 mL/h24 h/dayP = ? g/day

Practice exercise (made-up values, not clinical guidance). A tube feed with 40 g of protein per litre runs at 80 mL/h for 24 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 75 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 65 mL/h for 24 hours a day. The rest of the fluid is given as water flushes every 6 hours. What volume V is each flush? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). A critically ill woman is 168 cm tall and weighs 151 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.

GIR = mg/kg/min

Answer key

  1. 1. P = 76.8 g/day
  2. 2. R = 50 mL/h
  3. 3. V = 235 mL
  4. 4. R = 60 mL/h
  5. 5. E = 1371 kcal/day
  6. 6. GIR = 7.55 mg/kg/min
