1. What is the primary stain used in the Papanicolaou method?
A. Hematoxylin and eosin
B. Hematoxylin, Orange G, and EA
C. Giemsa
D. Wright's stain
Rationale: The Pap stain uses a combination of hematoxylin for
nuclei and counterstains like Orange G and EA (Eosin Azure) for
cytoplasm.
2. The transformation zone of the cervix is the area:
A. Where the endometrium meets the myometrium
B. Where squamous meets transitional epithelium
C. Where squamous epithelium meets columnar epithelium
D. Where vaginal mucosa meets vulvar skin
Rationale: This is the most common site for cervical neoplasia; it's
where metaplasia often occurs.
,3. Atypical squamous cells of undetermined significance (ASC-US) in a
Pap smear suggest:
A. High-grade squamous intraepithelial lesion
B. Normal finding
C. Mild abnormality, often reactive or HPV-related
D. Invasive carcinoma
Rationale: ASC-US indicates unclear significance and often warrants
HPV testing or repeat cytology.
4. Which fixative is most commonly used in gynecologic cytology?
A. Acetone
B. 95% Ethanol
C. Formalin
D. Bouin’s solution
Rationale: 95% ethanol is a rapid, effective fixative that preserves
nuclear detail for Pap stains.
5. The Bethesda System classifies cervical cytology primarily by:
A. Size of the lesion
B. Cell morphology and diagnostic category
C. HPV genotype
D. Staining characteristics
Rationale: The Bethesda System standardizes cervical cytology
reporting based on morphology.
6. Which of the following cells are a hallmark of herpes simplex virus
infection in a Pap smear?
A. Multinucleated giant cells with molding and margination
B. Koilocytes
C. Reed-Sternberg cells
D. Endometrial cells
, Rationale: Herpes shows characteristic cytopathic effect:
multinucleation, molding, and chromatin margination.
7. Which of the following is the best description of a koilocyte?
A. Neutrophil with fragmented nucleus
B. Squamous cell with perinuclear halo and nuclear atypia
C. Endocervical cell in clusters
D. Atypical glandular cell with vacuoles
Rationale: Koilocytes are classic markers of HPV effect.
8. An intraoperative cytologic smear is usually prepared using:
A. Tissue fixed in formalin
B. Whole blood
C. Fresh unfixed tissue
D. Stained Pap slides
Rationale: Rapid smears from fresh tissue are used for immediate
diagnosis during surgery.
9. Which hormone predominates in a Pap smear showing superficial cell
maturation?
A. Estrogen
B. Progesterone
C. Cortisol
D. Prolactin
Rationale: Estrogen promotes maturation of squamous cells to
superficial layers.
10. The purpose of the EA stain in the Pap procedure is to:
A. Stain nuclear detail
B. Differentiate cytoplasm of various cell types
C. Fix the specimen
D. Induce mitotic figures
, Rationale: EA stains cytoplasm of squamous and glandular cells
differently for differentiation.
11. The key feature of high-grade squamous intraepithelial lesion
(HSIL) is:
A. Multinucleation
B. Mild dysplasia
C. Marked nuclear enlargement and hyperchromasia
D. Abundant cytoplasm
Rationale: HSIL shows immature cells with dense, hyperchromatic
nuclei and high N/C ratio.
12. Which organism appears as "clue cells" on Pap smear?
A. Trichomonas vaginalis
B. Gardnerella vaginalis
C. Candida albicans
D. Herpes simplex
Rationale: Clue cells are squamous cells covered with bacteria,
characteristic of Gardnerella.
13. A liquid-based Pap test differs from a conventional smear in
that:
A. It is stained with H&E
B. It cannot detect microorganisms
C. The sample is suspended in preservative and filtered before slide
prep
D. It requires biopsy confirmation
Rationale: Liquid-based cytology processes specimens through
filtration or centrifugation.
