What is NOT indicated for the use of a non-tunneled catheter?

The use of a non-tunneled catheter is primarily indicated for short-term vascular access, particularly in emergent situations where rapid venous access is necessary. Non-tunneled catheters are designed for short-term use, typically less than a few weeks, making them suitable for emergent venous access and certain other acute care applications.

When considering the administration of non-irritant medications or hemodynamic monitoring, non-tunneled catheters can also be appropriate choices due to their ability to provide quick access to the vascular system. They can facilitate the administration of medications that are not harsh on the veins and allow for necessary monitoring of hemodynamic status in critically ill patients.

In contrast, long-term infusion of total parenteral nutrition (TPN) is not indicated for non-tunneled catheters. TPN is typically administered over prolonged periods and requires a more stable access option, which is better provided by a tunneled catheter. Tunneled catheters are specifically designed for long-term use as they have a lower risk of infection and can remain in place for weeks to months, which is essential for ongoing TPN therapy.

Thus, the option regarding long-term infusion of TPN is not appropriate for non-tunne
