- Define Immunity
Answer Immunity is the natural or induced resistance to infection and conditions associated with impaired response. HIV and AIDS is a virus that can only reproduce in the cells of a living organism. The virus causes havoc on an individual's immune system
- Pathopysiology
Answer · AIDS caused by HIV-1
a) Destroys body's ability to fight infection
b) Virus found in body fluids
c) Transmission modes
· Sexual contact · Infected blood via needle sharing · Transfusions of infected blood before 1985
d) Virus infects cells that have CD4 antigen
· Uses reverse transcriptase to convert viral RNA to DNA · Viral DNA integrated into host DNA · Duplicated during normal cell division
e) May remain inactive for years
f) Antibodies detectable in 6 weeks to 6 months
g) Helper T cells, CD4 cells primary infected cells
- Transmission 1 / 3
Answer · Infected body fluids (semen, blood, vaginal secretions, breast milk and cerebral spinal fluid)
· Same sex partners (more common in men/men relationships
2% for anal unpro- tected sex for the receptive male.)
· Sex with an infected partner · IV drug use (sharing of needles risk is less than 1%)
· Mother to baby from pregnancy after the birth immediately wash the baby down.
· Transmission from infected client to health care worker So, what should the nurse do if they are accidentally stuck with a needle used on a HIV patient? Clean immediately with soap and water, HIV test on the HCP, may start on antiretroviral drugs, Retest in 6-12 weeks.· When the viral load is higher is when you are more likely to transmit it, when it is low you are less likely to transmit it.
- Risk Factors
Answer · Behavior
using drug having or multiple partners
· Hemophilia and blood transfusions mainly if they had it before we had good testing and screening of blood products.
· Health care as an occupation · Poverty · Pregnancy and breast-feeding
· Older age mainly older women who have thinner vaginal walls
· Myths and misconceptions 2 / 3
it is not a death sentence, it is not transmitted by
touching, not transmitted by mosquitoes or toilet seats, can get it if you are straight and have multiple partners or partners that are not straight or who have had multiple partners.
- Stages of HIV
Answer
Early (A) also called the asymptomatic Phase
a) The interval between untreated HIV and the progression to AIDS is about 11 yrs or longer
b) CD4+ T cell counts remain above 500
c) Viral load in the blood is high Can have those first symptoms that go away (Fatigue, Headache,
low grade fever, night sweats, persistent lymphadenopathy)
d) Usually not aware that they are infected therefore they do not seek early treatment
- Stages of HIV
Answer
Intermediate (B)
a) CD4+ T cell count drops to 200-499
b) Viral load increases and HIV at a more active stage
c) Symptoms become worse
d) Localized infections, lymphadenopathy and nervous system manifestations
e) Most common infection- oropharygeal candidiasis or thrush, shingles, oral hairy
leukoplakia
