Last Patho Exam- HIV

Question 1

HIV

Answer 1

immune system impairment due to destruction of T cells and makes a patient more susceptible to infections and unusual cancers

Question 2

HIV

Answer 2

immune system impairment due to destruction of T cells and makes a patient more susceptible to infections and unusual cancers

Question 3

HIV is RNA or DNA based

Answer 3

RNA. HIV IS A RETROVIRUS

Question 4

If you have HIV does it mean you have AIDS

Answer 4

NOPE!!

Question 5

If you have AIDS does it mean you have HIV

Answer 5

YEP!!

Question 6

HIV is transmitted by,..

Answer 6

sexual contact - semen or vaginal fluids during unprotected sexual contact

contact with infected blood- needles

infected mothers to newborns inutero

Question 7

what is key in HIV transmission

Answer 7

PREVENTION!!!!!!!!!!!!!!

Question 8

what is seroconversion

Answer 8

the point at which the person converts from negative HIV to positive tests (1-6 months after exposure)

Question 9

Window Period

Answer 9

time after infection but before sreoconversion

HIV antibody test is negative but can transmit the virus

Question 10

HIV must invade living host cell in order to replicate. TRUE OR FALSE

Answer 10

TRUE

Question 11

CD4 antigen serves as..

Answer 11

receptor and allows HIV to invade cells

Question 12

HIV enters T cells where…

Answer 12

viral RNA is transcribed to DNA using enzyme reverse transcriptase

Question 13

what cell count drops and immune function is seriously impaired

Answer 13

CD4T

Question 14

can HIV mutate

Answer 14

yup!

Question 15

Stage 1

Answer 15

CD4 t-lymph count is >500. no aids defining condition
Window period
Test negative for antibodies
viral load high but and very infectious
fever, fatigue, rash for 1-2 weeks

Question 16

Stage 2: Latent Period

Answer 16

CD4 t-lymp cound is 200-499
no aids defining conditions
symptoms occur but not those related to AIDS

Question 17

Stage 3: AIDS phase

Question 18

viral load tests measure plasma

Answer 18

HIV RNA levels

Question 19

GI manifestations: opportunistic infections in HIV patients

Answer 19

Thrush and cytomegalovirus

both present with s/s of painful swallowing, retrosternal pain, inability to swallow and dehyration

Question 20

HAART

Answer 20

highly active antiretrivrial therapy

Not a cure, but it is treatment for lie.

Goal is to sustain suppression of HIV replication resulting in undetectable viral load and increasing CD4 cell count to slow progression of AIDS

Question 21

HIV is RNA or DNA based

Answer 21

RNA. HIV IS A RETROVIRUS

Question 22

If you have HIV does it mean you have AIDS

Answer 22

NOPE!!

Stage 2: Latent Period

Answer 34

CD4 t-lymp cound is 200-499 no aids defining conditions symptoms occur but not those related to AIDS

Question 35

Stage 3: AIDS phase

Answer 35

less than 200 CD4 and t-lymph remain stage 3 even if CD4 cells increase without treatment HIV will progress to AIDS after 7-10 years
