Introduction
The immune system is a complex network that protects the body from infection and abnormal cells. When functioning optimally, it identifies foreign invaders and mounts a targeted response. However, in clients with immune disorders—ranging from autoimmune conditions to HIV/AIDS—this protective system becomes compromised or overactive. Nurses must be equipped to identify risks, collect relevant clinical data, and implement interventions that promote immune health, prevent complications, and support recovery. This discussion explores the immunity processes and evidence-based strategies for managing patients with altered immune responses.
???? Case Study
Mr. Devon Lee, a 58-year-old male with a history of hypertension and type 2 diabetes, is admitted to the hospital with persistent fatigue, weight loss, and low-grade fever. His recent labs reveal leukopenia, a low CD4+ T-cell count, and positive ELISA and Western Blot tests, confirming HIV infection. He is started on combination antiretroviral therapy (cART). During his hospital stay, he develops oral candidiasis and a productive cough. The nurse assesses for signs of opportunistic infections and notes decreased appetite and mild confusion. In addition to managing Devon’s current symptoms, the care team must educate him on immune health promotion, monitor for complications, and initiate safety protocols to prevent infection transmission.
???? Discussion Prompt
Choose ONE of the following topic areas and respond thoroughly:
1. The Immune Response in HIV and Other Conditions
Describe the process of immunity, including the roles of T cells, B cells, and antibodies.
How is the immune response altered in HIV, autoimmune conditions, or allergic reactions?
What are the clinical implications of these changes in nursing care?
2. Identifying and Assessing Immune Disorders
What clients are at higher risk for immune dysfunction, and why?
What assessment data (labs, history, symptoms) should the nurse prioritize for early detection?
How can nurses distinguish immune-related concerns from other health problems?
3. Promoting Immune Health and Preventing Infection
What interventions support immune function in high-risk clients like Mr. Lee?
How can nurses promote nutrition, hygiene, and vaccination adherence?
How should the nurse evaluate effectiveness and monitor for complications such as opportunistic infections?
