What is a potential risk associated with total parenteral nutrition?

  1. Increased muscle mass

  2. Higher risk of complications, such as infection

  3. Improved digestive health

  4. Reduced nutritional intake

The correct answer is: Higher risk of complications, such as infection

Total parenteral nutrition (TPN) is a medical intervention that delivers nutrients directly into the bloodstream, bypassing the digestive system. While TPN is beneficial for patients who cannot eat or absorb nutrients through their gastrointestinal tract, it carries certain risks. One significant concern is the increased risk of complications, particularly infections. This occurs because TPN requires a central venous catheter for nutrient delivery, which can introduce pathogens into the bloodstream and increase the likelihood of bloodstream infections. Additionally, long-term use of TPN can lead to other complications, such as liver dysfunction, electrolyte imbalances, and metabolic disturbances, further underscoring the importance of careful monitoring and management of patients on TPN. The other options do not accurately reflect the potential risks associated with TPN. While increased muscle mass and improved digestive health may be goals of nutritional support, TPN does not inherently lead to these outcomes. Furthermore, TPN is designed to provide complete nutritional intake, so the concern here is not reduced nutritional intake but ensuring that the nutrient composition is adequate and meets the patient’s individual needs.
