A client who tested positive for the human immunodeficiency virus (HIV) antibodies is admitted to the hospital with Pneumocystis Jiroveci Pneumonia (PCP) and a CD4+T-Cell count of less than 200 cells/ul. Based on the diagnostic criteria established by the Centers of Disease Control and Prevention (CDC), which statement by the nurse is correct?

A. "The client meets the criteria for the chronic asymptomatic HIV infection phase": The chronic asymptomatic phase of HIV infection, is characterized by the presence of HIV antibodies with few or no symptoms and a CD4+ T-cell count above 500 cells/μL. This client’s CD4+ count is severely reduced, and opportunistic infection excludes classification as chronic asymptomatic. B. "The client meets the criteria for the acute HIV infection phase": The acute phase occurs shortly after initial HIV infection, often within 2–4 weeks, with symptoms resembling influenza or mononucleosis. This phase is not associated with opportunistic infections like PCP, nor with a CD4+ count below 200 cells/μL. C. "The client has developed acquired immunodeficiency syndrome (AIDS)": According to CDC criteria, a diagnosis of AIDS is made when an HIV-positive individual has a CD4+ T-cell count less than 200 cells/μL or presents with an AIDS-defining opportunistic infection, such as Pneumocystis jiroveci pneumonia (PCP). This client meets both criteria, confirming progression to AIDS. D. "The client’s CD4+ T cell count is within normal range": Normal CD4+ T-cell counts range from approximately 500–1,500 cells/μL. A count below 200 cells/μL indicates severe immunosuppression. Therefore, this client’s CD4+ count is far below the normal range and reflects significant immune compromise.
