HIV/AIDS Nursing Care

HIV is a retrovirus that infects and destroys CD4 (helper T) lymphocytes — the coordinators of the immune response. Untreated, CD4 counts fall over years until opportunistic infections and certain cancers define AIDS: a CD4 count below 200 cells/mm³ or an AIDS-defining condition.

Antiretroviral therapy (ART) suppresses replication so effectively that an adherent patient’s viral load becomes undetectable — and undetectable equals untransmittable (U=U): a sustained undetectable viral load means the virus is not transmitted sexually. Transmission otherwise occurs through blood, sexual contact, perinatal exposure, and shared injection equipment — never through casual contact, and exams test that distinction.

In the patient with advancing disease, assessment is an opportunistic-infection hunt: oral candidiasis (white plaques that scrape off), unexplained fevers and night sweats, new cough or dyspnea (Pneumocystis pneumonia presents with dry cough and exertional hypoxia), persistent diarrhea, headache or confusion (cryptococcal meningitis, toxoplasmosis), visual changes (CMV retinitis), weight loss and wasting.

Track the trends: a falling CD4 count, a climbing viral load, or a patient who has stopped refilling prescriptions are all findings that change the plan. Screen deliberately for depression and substance use — both predict the adherence failures that drive everything else.

Stigma is the second disease, and patients read staff behavior precisely — double-gloving for a blood pressure, hesitating at the door, or lowering the voice on the word “HIV” all communicate. Use person-first language, normalize the chronic-disease frame (“managed like diabetes — daily medication, regular labs”), and let the patient lead on disclosure decisions.

A new diagnosis lands as grief and fear regardless of prognosis. Give the U=U fact early — it changes how people see their future and their relationships — and connect them to peer support and case management before discharge.

Teach the regimen by name and time, what to do about a missed dose, and why “drug holidays” create resistance. Review interactions — including over-the-counter and herbal products like St. John’s wort, which can crash ART levels. Reinforce safer-sex practices, partner-testing resources, and that prevention tools (PrEP for partners, treatment as prevention) exist.

Report-now symptoms: fever, new cough or shortness of breath, headache with stiff neck or confusion, visual changes, white oral patches, persistent diarrhea. Keep every lab appointment — the CD4 and viral load are the disease’s dashboard.
