Which client scenario is most likely to require total parenteral nutrition (TPN)?

Which client scenario is most likely to require total parenteral nutrition (TPN)?

• A. A client diagnosed with type 1 diabetes in diabetic ketoacidosis.
• B. An obese client who is on a medically supervised starvation diet.
• C. An older client who is having a laparoscopic cholecystectomy.
• D. An acute exacerbation of Crohn's disease.

Answer: (A)

Total parenteral nutrition is used when the gastrointestinal tract cannot be used to deliver adequate nutrition, so nutrients are given intravenously through a central line to meet energy and protein needs. An acute Crohn's disease flare often leaves the gut inflamed and unable to tolerate enteral feeding, with poor absorption and possible risk of worsening symptoms. In this situation, resting the bowel and providing complete nutrition via the bloodstream helps support healing and prevent malnutrition, making TPN the most appropriate choice. In contrast, managing diabetic ketoacidosis centers on rapid IV fluid replacement, electrolyte correction, and insulin therapy, not TPN. Refeeding a severely obese patient on a supervised starvation plan typically begins with careful, gradual reintroduction of calories rather than full intravenous nutrition. After abdominal surgery like a laparoscopic cholecystectomy, most patients can start with oral or enteral nutrition unless complications arise, so TPN is not routinely indicated.
