TPN is a form of intravenous nutrition that provides glucose, amino acids, lipids, vitamins, minerals, and electrolytes to clients who cannot eat or absorb nutrients through their gastrointestinal tract. Discontinuing TPN abruptly can cause a sudden drop in blood glucose levels, leading to hypoglycemia .

Hyperglycemia can occur during TPN administration if the glucose infusion rate is too high or if the client has insulin resistance . Diarrhea can occur as a result of infection, bowel ischemia, or intolerance to enteral feeding . Hypertension can occur due to fluid overload, electrolyte imbalance, or vascular complications .
