Which condition would most warrant total parenteral nutrition (TPN)?

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

Answer: (D)

Total parenteral nutrition is used when the gut cannot be used for nourishment and intravenous feeding is needed to meet nutritional requirements. In an acute Crohn's disease flare, the bowel is inflamed and may be unable to tolerate regular intake, and there can be obstruction or poor absorption. Providing nutrition through the bloodstream allows the patient to receive calories, protein, and micronutrients while the inflammation is treated and the gut can rest and heal. Other scenarios involve a functioning GI tract or management priorities that don’t require IV nutrition: diabetes with diabetic ketoacidosis focuses on fluids, insulin, and electrolyte correction; a patient who has just had cholecystectomy can typically resume oral or tube feeding as tolerated; and an obese patient on a supervised starvation plan isn’t the situation where the bowel needs to be bypassed with TPN for long-term support.
