Who is at the highest risk for bloodstream infections while receiving normal saline via IV infusion?

The client with a non-tunneled central line in the left internal jugular vein is at the highest risk for bloodstream infections during IV infusion. Non-tunneled central lines are typically placed for short-term use and are more prone to complications, including infections, due to their placement directly into a major vein. This direct access to the bloodstream can provide an easier pathway for pathogens to enter, especially if proper sterile techniques are not maintained during insertion or maintenance.

Furthermore, non-tunneled central lines are often associated with higher rates of catheter-related bloodstream infections compared to other types of vascular access devices, such as tunneled catheters or implanted ports, which have a lower risk profile due to their design and the way they are accessed. This aspect of high-risk associated with non-tunneled central lines is critical for nursing practice because it highlights the need for vigilant infection control measures when managing these devices.
