The nurse is caring for a client who was recently diagnosed with human immunodeficiency virus (HIV). What is the nurse's priority in the client's plan of care?

A. Proper nutrition is important for maintaining the immune system and managing wasting syndrome in advanced HIV/AIDS. However, it is a supportive intervention rather than the primary priority in the initial management of a new diagnosis. Nutritional status can be addressed once the patient is stabilized on a therapeutic drug regimen that controls viral replication and preserves CD4 counts. B. Providing emotional support is a core component of nursing care for a client with a life-altering diagnosis like HIV. While addressing the psychological impact is essential for the patient's overall well-being and coping, it does not address the underlying physiological progression of the virus. Priority must be given to the intervention that most directly impacts long-term survival and prevents the progression to AIDS. C. Adherence to antiretroviral therapy (ART) is the absolute priority because consistent medication use is necessary to achieve viral suppression and prevent drug resistance. ART reduces the viral load to undetectable levels, which preserves the patient's immune function and virtually eliminates the risk of transmitting the virus to others. Failure to adhere to the strict dosing schedule is the leading cause of treatment failure in HIV. D. Prophylactic antibiotics are typically only indicated when the patient's CD4 count drops below specific thresholds (e.g., < 200 cells/mm3) to prevent opportunistic infections like Pneumocystis jirovecii pneumonia. Administering them to every newly diagnosed client regardless of their immune status is not standard practice. The focus should remain on ART to keep the immune system strong enough to prevent the need for prophylaxis.
