Quizplus · Accepted Answer

Total parenteral nutrition (TPN) is a method of providing nutrition directly into the bloodstream for patients who are unable to take food or absorb nutrients through their digestive system. TPN is usually given through a catheter inserted into a large vein, such as the subclavian vein or the jugular vein. Patients who may require TPN include those with severe gastrointestinal disorders, those who have undergone bowel surgery, and those who are unable to eat due to medical conditions like cancer or neurological disorders.
