Which statement is TRUE concerning bacteria?

A. Endogenous:

Endogenous infections originate from the client's own microbial flora. In this case, the infection was introduced by a procedure in a healthcare setting.

B. Health care-associated:

This urinary tract infection (UTI) developed after hospital admission due to a medical intervention (catheterization), classifying it as a health care-associated infection (HAI), also known as a nosocomial infection.

C. Exogenous:

Exogenous infections are caused by microorganisms from external sources (outside the body). While technically possible, the term HAI is more appropriate in this scenario.

D. Systemic:

A systemic infection affects the entire body (via the bloodstream). A UTI may become systemic if it progresses, but initially, it's a localized HAI.

A. Infections:

Infections in older adults are often due to immune suppression, not directly from autoantibodies.

B. Cancer:

While aging does increase cancer risk, autoantibodies do not directly cause cancer.

C. Allergic reaction:

Allergies involve hypersensitivity reactions to external antigens, not the body's own cells.

D. Autoimmune disease:

Autoantibodies target the body's own tissues, leading to autoimmune diseases such as rheumatoid arthritis or lupus, which are more common in older adults.
