2 kcal/mL1600 mL/day? mL/h18 h/day

Practice exercise (made-up values, not clinical guidance). A patient is prescribed 1600 mL of tube feed a day, run by pump over 18 hours. At what rate R do you set the pump, in mL/h? Round to the nearest whole number.

Practice exercise (made-up values, not clinical guidance). An 82 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 45 mL/h for 20 hours a day. The rest of the fluid is given as water flushes every 4 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 175 cm tall and weighs 133 kg. The practice protocol gives 12 kcal/kg of actual body weight per day if the BMI is 30–50 kg/m², and 24 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. R = 89 mL/h
  2. 2. E = 1560 kcal/day
  3. 3. R = 64 mL/h
  4. 4. V = 284 mL
  5. 5. E = 1596 kcal/day
  6. 6. GIR = 4.33 mg/kg/min
