HIV
Question | Answer |
---|---|
Human Immunodeficiency Virus | retrovirus that causes immunosuppression making a person more susceptible to infection depletes helper T cells, CD4 cells, and macrophages |
transmission of HIV | can be spread through contact with certain body fluids blood, semen, vaginal secretions and breast milk |
Patho of HIV | ribonucleic acid virus that replicates backward going from RNA to DNA CD4 + T cells are target for HIV immune problems start when CD4 + T cell count drops to < 500 cells |
normal range of CD4 + T cells | 800-1200 |
acute clinical manifestations of HIV | 2-4 weeks after infection, highly infectious flu-like symptoms- fever, swollen lymph nodes, sore throat, headache, malaise CD4 count will drop temporarily but quickly returns to baseline |
neurological complications of HIV | aseptic meningitis, peripheral neuropathy, facial palsy, Guillian-Barre Syndrome |
symptomatic infection - closer to 200 cells | persistent fever, frequent night sweats, chronic diarrhea, persistent vaginal candidal infection, herpes, thrush, severe fatigue, shingles |
AIDS | immune system severely compromised infection, opportunistic diseases, malignancies, wasting, cognitive changes |
diagnostics for HIV | detection of HIV antibodies / antigens in blood or saliva progression monitored via CD4 T cell count (decreases) and viral load (increases) |
goals of HIV therapy | decrease viral load, maintain CD4 + T counts, prevent HIV related symptoms and opportunistic infections, delay disease progression, prevent HIV transmission |
antiretroviral therapy | significantly slows progression but resistance develops rapidly if taken alone so 3 or more should be used |
drug interactions with HIV medications | herbal remedies, OTC (st john wart, antacids and PPIs) |
pre-exposure anaphylaxis | comprehensive strategy to reduce risk of sexually-acquired infections in adults who are high risk used in conjunction with condoms and regular testing EX- Tenofovir and Entricitabine (Truvada) |
nursing management of HIV | compliance with drug regimen, adopt healthy lifestyle, risk assessments, presentation of symptoms and early detection |
