Exam 3 Flashcards
(198 cards)
what are the 4 main body fluids HIV is commonly spread?
- blood
- semen
- breast milk
- vaginal secretions
HIV is most often transmitted through what? (3)
- sexual contact
- parenteral
- perinatal
what type of sexual contact is highest risk for HIV transmission?
anal sex
re: parenteral HIV transmission, what years were the higher risk years for transmission via blood products?
1978-1985 (before screening of blood products)
what are interventions for parenteral HIV transmission?
HARM REDUCTION
cleaning needles, needle exchange, PreP
how long should babies be treated with HIV drugs after delivery (from positive pregnant person)?
4-6 weeks post delivery
increased viral load means what?
increased chance of transmission
what is best thing health care workers can do to prevent HIV transmission?
standard precautions + use of safety needles
+ post exposure prophylaxis within 24 hours if exposed ◡̈
what does the 4th generation HIV testing detect? + in how many days?
HIV antibodies: 21 days
HIV p24 antigen: 14 days
if 4th gen HIV testing is positive, what is protocol? if negative, what is protocol?
positive –> test for HIV strain
negative –> test with another test (NAAT)
re: home testing kits for HIV, what should be done?
results verified w/further testing
what is viral load measuring? + what can it track?
amt of HIV viral RNA in blood
tracks: infectivity + therapy effectiveness
ideally, how often should a patient with positive HIV diagnosis be monitoring their viral load?
per Messer, q 2-3 months after diagnosis
what would we see re: these labs with AIDS?
lymphocytes:
CD4:
viral load:
lymphocytes: LOW w/fully progressed AIDS
CD4: decreases over time
viral load: increases over time (ART meds can mitigate this)
re: HIV/AIDS, CBC + CMP can help to track development of what?
opportunistic infections
what are the 3 stages of HIV/AIDS?
- acute (flu-like; VERY contagious)
- chronic (asymptomatic; can transmit to others)
- AIDS
what is timeframe to see acute HIV stage after transmission?
2-4 weeks after transmission
what are the 2 AIDS-defining parameters?
- CD4 <200
or - development of opportunistic infections
what is normal CD4? what are the CD4 counts associated with each HIV stage?
normal 500-1500
- acute: >500
- chronic: 200-499
- AIDS: <200
- unknown: not enough info about CD4 or opportunistic infections
who should be screened for HIV?
13-65 yrs old (at least one test)
higher risk/repeated high risk exposures (IVDU or sex workers) –> annually/frequently
what is the PRIORITY assessment of positive HIV/AIDS patient?
KNOW
early detection + management of infections
patient education
what is PRIORITY nursing care for patient with HIV/AIDS?
handwashing!! (infection risk - keeping patient safe)
what is most common opportunistic infection with AIDS?
KNOW
Pneumocystis pneumonia (PCP)
how does pneumocystis pneumonia present? (name s+s)
KNOW
PNA:
cough, dyspnea, SHOB, crackles in lungs, fever, tachypnea
