TPN
TPN (Total Parenteral Nutrition) is a specialized way of providing nutrition to patients who cannot eat normally. It's a method where nutrients are delivered directly into a patient's bloodstream through an IV line, bypassing the digestive system. Dietitians and healthcare professionals use TPN when managing patients who can't get nutrition through regular eating or tube feeding. Understanding TPN is crucial for dietitians because they need to calculate, monitor, and adjust these specialized nutrition formulas to meet each patient's needs.
