What assessment finding indicates a potential complication of a central venous catheter?

The presence of redness and swelling at the insertion site of a central venous catheter is a significant assessment finding that may indicate a potential complication, such as infection or thrombosis. These symptoms suggest that there might be localized inflammation, which can arise from various issues including an infection at the catheter insertion site.

Infections related to central venous catheters can lead to serious complications if not identified and treated promptly. The redness and swelling are typically associated with an inflammatory response, signaling that the body is reacting to a potential infection or irritation caused by the catheter itself.

While increased heart rate, decreased urine output, and elevated blood pressure can all signify complications, they are not as directly associated with the immediate complications of catheter insertion as the localized signs of infection or thrombosis are. Hence, the assessment finding of redness and swelling at the insertion site is crucial for the early identification of catheter-related complications.
