Why might a patient require the administration of total parenteral nutrition through a CVAD?

• A. To enhance weight loss
• B. If they are unable to eat
• C. For regular hydration needs
• D. For minor surgical recovery

Answer: (B)

A patient may require the administration of total parenteral nutrition (TPN) through a central venous access device (CVAD) specifically when they are unable to eat. TPN is a method of supplying all necessary nutrients directly into the bloodstream, bypassing the digestive system entirely. This is particularly important for patients who have conditions that impair their ability to consume food orally or absorb nutrients adequately. For example, individuals with gastrointestinal disorders, those recovering from major surgery, or patients with certain types of cancer may not be able to eat or may require nutrition that cannot be achieved through oral intake. The use of a CVAD for TPN allows for the delivery of larger volumes of fluid and provides a more stable access point for nutrition that can be quite concentrated. This route is vital for patients who have prolonged needs for nutritional support, ensuring that they receive the appropriate caloric intake and necessary vitamins and minerals efficiently. In contrast, enhancing weight loss or addressing regular hydration needs, while important, do not justify the use of TPN in the same way, as TPN is intended for nutritional support rather than weight management or routine fluid replacement. Additionally, for minor surgical recovery, most patients might still be able to consume food orally or have less complex nutritional needs than
