Ch. 37 Management of Patients with HIV infection and AIDS
What is primary infection of HIV disease?
AKA acute HIV infection or acute HIV syndrome Part of CDC category A Symptoms: none to flulike syndrome Window period: lack of HIV antibodies Period of rapid viral replication and dissemination through the body Viral set point: balance between amount of HIV and the immune response
What are some nursing interventions for bowels for HIV?
Assess bowel pattern and factors that may exacerbate diarrhea Avoid foods that act as bowel irritants, such as raw fruits and vegetables, carbonated beverages, spicy foods, and foods of extreme temperatures Small, frequent meals Administer medications as prescribed Assess and promote self-care strategies to control diarrhea

What is the nursing process assessment for a patient with HIV?
Assess physical and psychosocial status Identify potential risk factors: IV drug abuse, risky sexual practices Immune system function Nutritional status: n/v, anorexia, oral pain, diff swallowing Skin integrity: inspection vital Respiratory status: cough, sputum, sob, orthopnea, tachypnea, chest pain Neurologic status: level of consciousness, orientation, memory, sensory deficits, motor involvement and any seizures Fluid and electrolyte balance Knowledge level
What is the HIV infection stages?
Attachment of the HIV virus to an uninfected CD4+ receptor Uncoating: contents of HIV's viral core emptied into CD4+ T cell DNA synthesis: reverse transcription produces a mirror image of the viral RNA and double-stranded DNA molecule Integration of viral DNA into host DNA Transcription of the inserted viral DNA to produce viral messenger RNA Translation of viral messenger RNA to create viral polyprotein Cleavage of the viral polyprotein into individual viral proteins that make up the new virus Assembly and release of the new virus from the host cell
What is HIV asymptomatic?
CDC category A More than 500 CD4+ T lymphocytes/mm3 Upon reaching the viral set point, chronic asymptomatic state begins Body has sufficient immune response to defend against pathogens
What is HIV symptomatic?
CDC category B 200-499 CD4+ lymphocytes/mm3 CD4 T cells gradually fall The patient develops symptoms or conditions related to the HIV infection, which are not classified as category C conditions. Patients who are once treated for a category B condition are considered category B.
What is AIDS?
CDC category C Less than 200 CD4+ lymphocytes/mm3 As levels drop below 100 cell/mm3 the immune system is significantly impaired. Development of listed conditions Candidiasis of bronchi, trachea, lungs and esophagus Cervical cancer, invasive See table in text
What is some health care provider treatment?
Consent for baseline HIV, hepatitis B and C Get postexposure prophylaxis for HIV according the CDC guidelines Start within 2 hours after exposure Monitor for symptoms of toxicity Practice safe sex Continue HIV medications for the full 4 weeks after exposure Follow up with postexposure testing at 1 month, e months, 6 months and 1 year Documentation
What are some lab tests to diagnose and track HIV?
EIA- antibodies are detected, resulting in positive results and marking the end of the window period Western period- also detects antibodies to HIV, used to confirm EIA Viral Load- measures HIV RNA in the plasma CD4/CD8- these are the markers found on lymphocytes. HIV kills CD4+ cells, which results in a significantly impaired immune system OraQuick- in home HIV test

Stages of HIV disease?
HIV asymptomatic (more than 500 CD4+ T Lymphocytes): Patients feel well and have few symptoms because CD4+ T-cell levels remain high enough to preserve immune defensive responses HIV symptomatic (200-499 CD4+ T Lymphocytes), AIDS: CD4+ T-cell level drops below 200 When the levels drop below 100, the immune system is significantly impaired Important for entitlements: housing, disability benefits and food stamps)
What are emotional and ethical considerations for someone with HIV?
Health care professional concerns: fear of infection, responsibility for giving care, values clarification, confidentiality, poor prognostic outcomes Stigmatized behaviors: nurses may not want to take care Patient's right to privacy Sexual partners should know about the potential for infection Unlike cancer, AIDS is associated with controversies challenging our legal and political systems as well as religious and personal beliefs

Ineffective airway clearance Pain Imbalanced nutrition Social isolation Anticipatory grieving Deficient knowledge Impaired skin integrity Diarrhea Risk for infection Activity intolerance Disturbed thought processes

Integumentary: herpes zoster & herpes simplex Gynecologic: candidiasis, genital ulcers put females at risk for contracting HIV, HPV, cervical neoplasms, PID, menstrual abnormalities
What are clinical maifestations of HIV/AIDS: oncology?
Kaposi's sarcoma: common in men who have sex with men Endothelial layer of blood and lymphatic vessels Cutaneous lesions (brownish pink to deep purple) but may involve multiple organ systems Lesions cause discomfort, disfigurement, ulceration, and potential for infection Visceral involvement: lymph nodes, GI tract and lungs B-cell lymphomas: develop outside the lymph nodes, brain, bone marrow and GI tract
What are some nursing interventions for nutrition for HIV?
Monitor weight, I&O, dietary intake, and factors that interfere with nutrition Dietary consult Control of nausea with antiemetics Oral hygiene Treatment of oral discomfort Dietary supplements May require enteral feedings or parenteral nutrition
What are some gerentology considerations for people with HIV?
One quarter of people living with HIV are older than age 50 years. Reasons Unprotected intercourse Do not consider themselves at risk Social bias toward homosexuality May use IV drugs May have received HIV-infected blood before 1985 Reduction in immune system function
