HIV/AIDS.
immune and transmissible disorders
Question | Answer |
---|---|
WBC (types) | Neutrophils, Macrophages, Basophils, Eosinophils, Monocyte, B-lymphocyte, T-lymphocyte |
Types of T-lymphocytes | helper/inducer T-cells, suppressor T-cells, cytoxic/cytolytic T-cells, Natural killer cells |
What is CD4+ | type of T-lymphocyte (cell-mediated immunity) |
What is AIDS | late stage of symptoms that result from infection from HIV |
What is the normal CD4+ count | 500-1600 cells/mm^3 |
What does the HIV infection cause | profound immunosuppression |
What is HIV | a retrovirus |
Patho of HIV/ Action of infection on human DNA | retrovirus enzymes for the DNA synthesis apparatus use viral RNA as a pattern and make human DNA similar to viral RNA |
What is reverse transcriptase | enzyme within retrovirus that increased the efficiency of viral replication once the retrovirus enters the human cell. |
What does HIV do to WBC | attach, infect, destroy CD4+ lymphocytes and macrophages causing malfunction and immunosuppression. |
Prevention of HIV | education, universal precautions |
Modes of Transmission of HIV | Sexual, Parenteral, Perinatal, (occupation=health care) |
Types of opportunistic infections | Protozoal, Fungal, Bacterial, Viral |
Protozoal | Pneumocytosis carinii Pneumonia, Toxoplasmosis Encephalitis, crytosporidiosis |
Fungal | Candida albicans, cryptococcosis, histoplasmosis |
Bacterial | (MAC) Mycobacterium avium-intracellulare complex, mycobacterium tuberculosis, |
Viral | cytomegalovirus (CMV), herpes simplex virus (HSV), varicella-zoster virus (VZV) |
Malignancies | Kaposi's sarcoma, Maligant lymphoma |
HIV/AIDS-related disorders | AIDS dementia complex (ADC), Wasting syndrome |
Integumentary changes of HIV/ AIDS | rashes, lesions |
Lab. Assessment | Decreased Lymphocyte Ct, WBC, CD4+ ct |
Types of Antibody tests | EIA (ELISA), Western Blot |
What is a viral culture | looks for presence of HIV (RNA or protein), measures reverse transcriptase |
Viral Load testing | look at RNA, measures disease progression, response to treatment, low#=good |
Quantitative RNA assays | measure |
P24 antigen assay | core protein of HIV is R 24, measures response to drugs |
What is the window period | time it takes for infectious antigens to convert to HIV (sero-convert), (- to +), 3 weeks to 3 months or more) up to a year) |
Nursing Diagnoses | Risk for Infection Risk for FVD |
Drug Therapy...classes of antiretroviral drugs | HAART, NRTI, Non-NRTI, Protease inhibitors, Fusion Inhibitors, Ribonucleotide reductase inhibitors |
