Which of the following is a sign of a vascular access infection?

Fever is a classic sign of infection and can indicate that the body is responding to a bacterial invasion, particularly in the context of vascular access. When an infection occurs, the immune system responds by raising the body's temperature to help fight off pathogens. In patients with vascular access, such as those receiving dialysis, the presence of fever may suggest that the site of access is infected or that systemic infection has developed.

Monitoring vital signs and other symptoms is critical in a clinical setting, and recognizing fever as a potential indicator of infection allows healthcare professionals to act promptly. It is essential in managing patient care effectively and can guide further diagnostic testing and treatment options.
