A 25-year old female patient recovering from surgery to correct an intestinal obstruction needs complete bowel rest which necessitates the use of Total Parenteral Nutrition (TPN). The patient was 10 pounds underweight prior to surgery and is occasionally febrile. Which of the following formulations would be most appropriate for this patient?
  1. 30 kcals, 1 g protein, 30 ml fluid per kg/body weight;100 mg vitamin C, 5 mg zinc per day
  2. 45 kcals, 2 g protein, 35 ml fluid per kg/body weight; 200 mg vitamin C, 6 mg zinc per day
  3. 60 kcals, 3 g protein, 40 ml fluid per kg/body weight; 500 mg vitamin C, 10 mg zinc per day
  4. None of the above
Explanation
Answer: B - The formula which would be most appropriate for this patient would contain 45 calories, 2 grams of protein, and 35 ml water per kg of body weight per day, as well as 200 mg of vitamin C and 6 mg of zinc. Starting with an intermediate level of caloric and protein intake, along with moderate vitamin C and zinc to promote healing, allows staff to monitor the patient’s progress and determine if adjustment in the formula is needed.
