Exam 6- hiv/ cancer/ reproductive Flashcards
(226 cards)
Hiv is retrovirus-
attacks what
specifically what
attacks what ability
attacks immune system-
specifically t cells
This attacks the ability to fight infections
Risk factors HIV
what infections
what sex
multiple
what sex
what use
hx
what exposure
sti infections,
male to male sex,
multiple partners
Unprotected sex,
iv drug use,
hx of blood transfusion,
peri/breast milk exposure
Hiv is present in
s
b
v s
b m
c
s
semen,
blood,
vaginal secretions,
breast milk,
csf,
saliva
HIV is not present in
u
s
urine
stool
what does being a retrovirus mean- carries information where
How does HIV work in the body? (patho)
carries information in rna
when HIv enters body- affects what cells
once inside cell- does what
When it enters body- affects cells that are a T lymphocyte(CD4 antigen)
Once inside cell- Virus will shed its coat and convert from rna to DNA
HIV does what with DNA
does what to host cell
DNA is then duplicated into host cell and duplicated during cell division
Kills host cell
cannot detect HIV until what takes place
how long do you need to wait to detect
Cannot detect HIV until seroconversion has taken place- this is when the Body tries to make antibodies against HIV
Starts from 6 weeks to 6 months after initial exposure
is hiv testing confidential
yes
Acute/initial exposure stage-
wait how long for testing
is it still contagious
wait 6 weeks and up to 6 months for seroconversion-
you can still spread to others at all stages
Primary/acute infection Early HIV s/s-
unexplained
n s
/
d
f
m
what like symptoms
unintentional
swollen
unexplained fever,
night sweats,
n/v, diarrhea,
fatigue,
malaise
, flu-like symptoms ,
unintentional Weight loss,
swollen lymph nodes
Stage 2- asymptotic stage ”recovery/dormant stage”
what s/s
are they contagious
- no external symptoms/no s/s-
host is still contagious-
Stage 3- symptomatic-
what is developed
s/s
f
m
what loss
what skin
r
aids is developed- end stage-
appearance of infections-
fever,
malaise,
wt loss,
dry skin,
rash
Stage 3- symptomatic-
pt needs what
pt needs hospice, palliative care, comfort care, cannot go back
ELISA test-Most widely used to diagnose HIV
what does it test for
does not detect what
HIV Labs and Diagnostics
Tests for the HIV antibodies,
does not detect active virus
ELISA TEST
best used how long into exposure
HIV Labs and Diagnostics
99.5% or higher sensitivity when performed at least 13 weeks after infection
False negative is possible if prior to 13week exposure mark
why also need an absolute CD4 lymphocyte count
monitors what-
HIV Labs and Diagnostics
monitors progress of disease and how treatment plan is working
HIV rapid antibody Test4
what type of test
interpreted how
HIV Labs and Diagnostics
Rapid test in office, with strips that turn varied colors
Interpreted visually
HIV Viral Load Tests
measures what
HIV Labs and Diagnostics
Measure amount of actively replicating HIV
HIV Viral Load Tests
correlates to:
what progression
what response
HIV Labs and Diagnostics
Correlate to
disease progression
and response to AR medications
CBC-Used to detect
a
L
t
L
HIV Labs and Diagnostics
anemia
Leukopenia
Thrombocytopenia
Lymphopenia
may need what for potential HIV exposure
get what in females
May need to rule out other things, like getting tb test, mri
cultures for infections,
and get pap smears on females- cervical caner risk is increased
HAART meds management in HIV
what stands for
what type of drugs
Highly
Active
Antiretroviral
Therapy
“ine” “vir” drugs
med management -hiv
what is barrier for meds
why do they need strict compliance
need what plan
always do what
Medications are very expensive
Explain need for compliance with patients-can go into aids if miss an hour
need a missed dose plan
always have meds
