What is an important nursing intervention for a client receiving total parenteral nutrition (TPN) through a central venous access device?

Ensuring the client is in the supine position before changing the tubing is an important nursing intervention for a client receiving total parenteral nutrition (TPN) through a central venous access device. This position helps to minimize the risk of air embolism, which can occur if the central line is disrupted while in an upright position. When the client is supine, the central venous pressure is more stable, and it reduces the chances of air entering the bloodstream during the procedure. This precaution is especially critical as TPN is delivered through a central line, which directly connects to the bloodstream, making it vital to follow strict protocols to ensure patient safety and prevent complications.

Other options either do not address the essential safety measures needed during the administration and manipulation of TPN or pose a risk to the client. For instance, administering medications via the same line as TPN can lead to compatibility issues or dilution of TPN formula. Starting TPN while the client is sitting can also pose a risk of air embolism. Understanding the importance of positioning during these interventions is key to maintaining client safety and integrity of the central venous access.
