Hiv - Nursing Case Study

Pathophysiology

• Primary mechanism: HIV targets and infects CD4+ T cells, a type of white blood cell crucial for immune function, leading to a progressive decline in their numbers. This weakens the immune system, making the body more susceptible to infections and diseases.

• Secondary mechanism: Once inside the CD4+ T cells, HIV uses reverse transcriptase to convert its RNA into DNA, integrating into the host cell's DNA. This allows the virus to replicate and spread throughout the body, further depleting CD4+ T cells.

• Key complication: The significant reduction in CD4+ T cells eventually leads to Acquired Immunodeficiency Syndrome (AIDS), characterized by opportunistic infections and certain cancers, which the weakened immune system can no longer effectively combat.

He reports no new symptoms since his last appointment and mentions feeling generally healthy and active in his daily life. His adherence to the prescribed medication regimen of Emtricitabine/Tenofovir (Truvada) is excellent, as confirmed by his medication refill history and self-report. The patient's vital signs are stable: blood pressure is 118/76 mmHg, heart rate is 72 bpm, respiratory rate is 16 breaths per minute, temperature is 98.6°F, and oxygen saturation is 98% on room air, all indicating a stable condition.

The physical examination shows no signs of opportunistic infections or significant weight loss, and the patient's weight and body mass index remain within normal limits for his age and height. Skin examination reveals no rashes or lesions commonly associated with HIV-related complications. The patient expresses a positive outlook and demonstrates good understanding and engagement with his health management plan. These findings suggest that the patient is maintaining a stable early stage of HIV with effective viral suppression, minimizing the risk of progression to AIDS.

The nurse documents these findings and reinforces the importance of ongoing adherence to antiretroviral therapy, regular follow-up visits, and routine laboratory monitoring. The patient is reminded of the significance of maintaining a healthy lifestyle, including a balanced diet, regular exercise, and stress management, to support immune function. The next step in the patient's care involves ordering updated laboratory tests to monitor CD4+ T cell count and viral load, which will provide further insight into the effectiveness of the current treatment plan and guide future clinical decisions.
