Q

how do neoplastic cells appear under colposcopy when acetic acid is applied?

A

the acid dehydrates the cell and causes precipitation of nucleic proteins - neoplastic cells appear whiter b/c of higher nucleus/cytoplasm ratio

16
Q

what is the one circumstance underwhich a colposcopy would be rendered inadequate?

A

if the transformation zone is not fully visualized

17
Q

t or f: cervical biopsy is contraindicated in pregnancy

A

FALSE (endo cervical curretage IS however contraindicated)

18
Q

what are some contraindications to cervical biopsy?

A

PID and cervcitis

19
Q

what is the next step after biopsy results or ECC is positive for CIN II or III?

A

cone biopsy or LEEP ( loop electrosurgical excision procedure )

20
Q

from where is the specimen taken for cone biopsy?

A

cone shaped piece of the endocervical canal is taken

21
Q

desrcibe the LEEP?

A

a small wire loop with an electric current is used to excise the TZ and endocervix

22
Q

what is the one drawback for evaluation of biopsy margins with LEEP? (THINK …)

A

it can be difficult due to thermal artifact

23
Q

please describe how to properly dispense the gardasil vaccine.

A

3 doses of 0.5mL IM at 0 2 and 6 months

24
Q

against which types of HPV does the gardasil vaccine protect against?

25
what was the first bivalent HPV vaccine approved and for which types does it cover?
cervarix, types 16 and 18
