📚 HIV/AIDS — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
HIV is a retrovirus that infects and destroys CD4 (helper) T-cells, progressively weakening cell-mediated immunity. AIDS is the advanced stage, defined by a CD4 count below 200 or the presence of an AIDS-defining opportunistic infection. It is transmitted through blood, semen, vaginal/rectal fluids, and breast milk, NOT through casual contact, hugging, or sharing utensils. Antiretroviral therapy (ART) suppresses viral load and lets people live long lives, but adherence is everything.
🔑
Key points
Understand these first
HIV targets CD4 T-helper cells; as CD4 count falls, the patient becomes vulnerable to opportunistic infections.
Acute (seroconversion) illness looks like flu or mononucleosis: fever, fatigue, sore throat, rash, and lymphadenopathy.
AIDS is diagnosed when CD4 drops below 200 cells/mm3 or an AIDS-defining illness (PCP pneumonia, Kaposi sarcoma, esophageal candidiasis) appears.
Opportunistic infections such as Pneumocystis jirovecii pneumonia, TB, cytomegalovirus, and toxoplasmosis are the major causes of death.
Standard precautions are used for routine care; HIV alone does not require an isolation room.
An undetectable viral load on consistent ART means the virus is effectively untransmittable sexually (U=U).
✅
Nursing priorities
What to do, in order
Reinforce strict, lifelong ART adherence at the same times daily; skipped doses drive resistance.
Apply standard precautions consistently and monitor for and prevent opportunistic infections.
Monitor CD4 count and viral load trends to gauge immune status and treatment response.
Promote nutrition, vaccination per protocol, and prophylaxis (such as TMP-SMX) when CD4 is low.
Provide nonjudgmental emotional support and connect the patient to counseling and community resources.
🚩
Red flags — report now
Escalate immediately
New fever, productive cough, dyspnea, or oxygen desaturation may signal PCP or another opportunistic infection that must be reported now.
New neurologic changes (confusion, headache, focal deficits, seizures) can indicate toxoplasmosis or CNS lymphoma and need urgent evaluation.
A CD4 count falling below 200 demands prompt provider notification to start opportunistic-infection prophylaxis.
Never breastfeed if HIV positive in settings where safe formula is available; transmission risk is real.

Labs & values
Numbers to know
CD4 T-cell count normal 500-1600 cells/mm3 (AIDS-defining if below 200)
HIV viral load goal: undetectable (below ~20-50 copies/mL)
WBC normal 5,000-10,000/mm3
🗣️
Patient teaching
What patients must know
Take antiretroviral medication exactly as prescribed every single day, even when feeling well, to keep the virus undetectable.
Use condoms and do not share needles or razors; an undetectable viral load greatly lowers but should not replace barrier protection per provider guidance.
Avoid raw or undercooked foods, unpasteurized products, and contact with reptiles or cat litter to reduce infection risk.
❓ HIV/AIDS: NCLEX FAQs
What are the priority nursing interventions for HIV/AIDS?
Reinforce strict, lifelong ART adherence at the same times daily; skipped doses drive resistance. Apply standard precautions consistently and monitor for and prevent opportunistic infections. Monitor CD4 count and viral load trends to gauge immune status and treatment response. Promote nutrition, vaccination per protocol, and prophylaxis (such as TMP-SMX) when CD4 is low.
What are the warning signs of HIV/AIDS a nurse must report?
New fever, productive cough, dyspnea, or oxygen desaturation may signal PCP or another opportunistic infection that must be reported now. New neurologic changes (confusion, headache, focal deficits, seizures) can indicate toxoplasmosis or CNS lymphoma and need urgent evaluation. A CD4 count falling below 200 demands prompt provider notification to start opportunistic-infection prophylaxis. Never breastfeed if HIV positive in settings where safe formula is available; transmission risk is real.
