What complication should a nurse assess for in a client receiving total parenteral nutrition (TPN)?

Clients receiving total parenteral nutrition (TPN) are at risk for several complications, one of which is infection. TPN is typically administered through a central venous catheter, which provides direct access to the venous system. This route, while beneficial for nutrient delivery, increases the risk of introducing pathogens that can cause infections such as catheter-related bloodstream infections.

The high concentration of glucose in TPN solutions also creates an environment conducive to bacterial growth if the system is not handled with stringent aseptic techniques. Therefore, nurses must monitor for signs of infection, including fever, inflammation at the catheter site, and changes in laboratory values indicative of infection, such as elevated white blood cell counts.

Other potential complications include metabolic disturbances, such as electrolyte imbalances and complications related to the cardiovascular system, but priority in assessments should focus on the risk of infection given the method of nutrition delivery.
