When is total parenteral nutrition (TPN) used?

• A. Cancer of the digestive tract, IBD, Crohn's disease, high risk for aspiration, GI obstruction
• B. Only for dehydration
• C. For all patients as routine care
• D. Only after gastric surgery

Answer: (A)

Total parenteral nutrition is used when the gut cannot be used to meet a patient’s nutritional needs or when bowel rest is needed, delivering nutrients directly into the bloodstream. It’s especially indicated when digestion or absorption is impaired by GI conditions or when enteral feeding isn’t feasible. That includes cancers of the digestive tract, inflammatory bowel disease such as Crohn’s, and other GI diseases that compromise nutrition. It’s also chosen when there’s a high risk for aspiration or a GI obstruction that prevents food from passing through the gut. Dehydration is treated with IV fluids and electrolytes, not TPN, and TPN is not routine care for all patients. It isn’t limited to after gastric surgery, though it can be used postoperatively in certain cases if needed.
