Practice exercise (made-up values, not clinical guidance). A 57 kg patient has a fluid goal of 35 mL/kg/day and receives all fluid through a feeding tube. The formula is 81% free water and runs at 50 mL/h for 20 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). Over 24 hours a patient receives 1200 mL of parenteral nutrition with final concentrations of 17.5% dextrose and 5% amino acids, plus 100 mL of 20% lipid emulsion (2 kcal/mL). Find the total energy E the patient receives in kcal per day. Round to the nearest whole number.

GIR = mg/kg/min

Answer key

  1. 1. R = 75 mL/h
  2. 2. P = 44.1 g/day
  3. 3. V = 296 mL
  4. 4. V = 256 mL
  5. 5. E = 1154 kcal/day
  6. 6. GIR = 6.11 mg/kg/min
