Which procedure is commonly performed to evaluate an abnormal Pap smear?

• A. Colposcopy
• B. Dilation and curettage
• C. Rectovaginal palpation
• D. hCG test

Answer: (A)

When a Pap smear comes back abnormal, the usual next step is to examine the cervix more closely with a colposcope. This instrument lets the clinician magnify the cervix and apply dilute acetic acid to highlight areas of abnormal epithelium as white or otherwise suspicious regions. From these highlighted areas, a directed biopsy is often taken to determine the exact grade of cervical intraepithelial neoplasia and to guide treatment.

Other options don’t fit this purpose. A dilation and curettage examines the lining of the uterus, not the cervix, and is not the standard way to evaluate an abnormal Pap result. Rectovaginal palpation is a pelvic exam technique for feeling masses, not for diagnosing cervical changes. The hCG test checks pregnancy status and doesn’t assess cervical tissue or cytology.
