A nurse is performing a health history with a client who reports that they think they have lupus.
Which of the following statements made by the client would help validate this diagnosis?

Choice A rationale

Osteoarthritis is a non-inflammatory degenerative joint disease characterized by cartilage breakdown. While it causes pain and functional impairment, it does not directly suppress the immune system or increase susceptibility to opportunistic infections. The risk for opportunistic infections is directly related to impaired cellular immunity.

Choice B rationale

Rheumatoid arthritis (RA) is a chronic autoimmune disease causing systemic inflammation. While the disease itself can affect the immune system, the highest risk for opportunistic infection typically arises from the immunosuppressive medications used to treat the flare-up (e.g., corticosteroids, biologics), rather than the disease state alone.

Choice C rationale

A client with HIV (Human Immunodeficiency Virus) experiences a progressive decline in the number and function of CD4+ T-lymphocytes. These cells are central to cell-mediated immunity, and their depletion allows opportunistic pathogens (e.g., Pneumocystis jirovecii, Mycobacterium avium) that are normally controlled by a healthy immune system to cause severe, life-threatening infections.

Choice D rationale

A client with a risk of severe anaphylaxis has a hyperactive immune response (Type I hypersensitivity) to an antigen. This is an inappropriate, exaggerated immune reaction that is not characterized by generalized immunosuppression; therefore, it does not increase the risk for opportunistic infections.

Choice A rationale

The initial phase of HIV infection, known as acute retroviral syndrome (ARS), typically occurs 2 to 4 weeks after exposure. This syndrome is characterized by a high viral load and a significant drop in CD4+ T-lymphocyte count as the virus disseminates throughout the body. Manifestations closely mimic a severe viral infection, presenting as mononucleosis-like or flu-like symptoms, including fever, fatigue, swollen lymph nodes (lymphadenopathy), sore throat, and night sweats.

Choice B rationale

Pneumocystis jirovecii pneumonia (PCP) is an opportunistic infection that typically manifests in the late stages of HIV infection when the immune system is severely compromised, specifically when the CD4+ T-lymphocyte count falls below 200 cells/mm (Normal range is typically 500 to 1,500 cells/mm). It is a defining illness of AIDS, not an initial symptom of acute HIV infection.

Choice C rationale

Kaposi's sarcoma (KS) is a cancer caused by the Kaposi's sarcoma-associated herpesvirus (KSHV) and is also considered an AIDS-defining illness. Its appearance signals significant immunosuppression, typically occurring when the CD4+ T-lymphocyte count is very low. This manifestation involves the growth of abnormal blood vessels and is not characteristic of the initial, acute phase of HIV infection.

Choice D rationale

Increased susceptibility to various fungal and bacterial infections (e.g., severe thrush, recurrent bacterial pneumonia) is a direct consequence of the progressive damage to the immune system caused by the sustained high viral load and the gradual, chronic destruction of CD4+ T-lymphocytes. This vulnerability to opportunistic and recurrent infections is characteristic of the clinical latency period or, more commonly, the advanced stage of HIV disease (AIDS), not the initial presentation.
