Question 1

Which of the following best describes the transformation zone (TZ) of the cervix and its clinical significance in cervical screening?

Accepted Answer

The area where columnar epithelium is replaced by metaplastic squamous epithelium, and is the most common site for the development of cervical neoplasia.

Question 2

A 30-year-old woman attends for cervical screening. Her sample is taken during days 12-14 of her menstrual cycle. Why is this timing optimal for sample collection?

Accepted Answer

Oestrogen levels peak, resulting in a thickened squamous epithelium and abundant superficial cells for sampling.

Question 3

Which of the following statements about liquid-based cytology (LBC) is CORRECT?

Accepted Answer

LBC improves cell preservation, reduces inadequate rates, and allows for multiple tests from a single sample.

Question 4

A cytology slide shows cells with increased nuclear-to-cytoplasmic ratio, irregular nuclear outlines, and hyperchromasia. Which grade of dyskaryosis is most likely present if the n:c ratio is up to 50%?

Accepted Answer

Low grade dyskaryosis

Question 5

Which HPV subtypes are most commonly associated with cervical cancer, and are targeted by the original Gardasil vaccine?

Accepted Answer

HPV 16 and 18

Question 6

A cytology sample is stained with Papanicolaou stain. Which component stains the nucleus, and what is its typical color?

Accepted Answer

Haematoxylin; blue-black

Question 7

Which of the following best explains why cervical screening is still necessary after HPV vaccination?

Accepted Answer

The vaccine does not protect against all high-risk HPV types, and screening detects pre-cancerous changes regardless of vaccination status.

Question 8

Which of the following cell types is characterized by a polygonal shape, pink/orange cytoplasm, and a small, pyknotic nucleus with no chromatin detail?

Accepted Answer

Superficial squamous cell

Question 9

A cytology sample reveals thick, filamentous hyphae with cross walls and budding spores. Which infection is most likely present?

Accepted Answer

Candida albicans

Question 10

Which of the following best describes the PCR process used in HPV testing?

Accepted Answer

DNA is denatured at $$95^\circ C$$, primers anneal at $$50-65^\circ C$$, and DNA polymerase extends at $$72^\circ C.$$

Question 11

Which of the following is a key advantage of the NHS Cervical Screening Programme introduced in 1988?

Accepted Answer

Fully computerised call/recall system and improved follow-up.

Question 12

A cytology slide shows a predominance of intermediate cells with blue cytoplasm and larger nuclei. Which hormone is likely predominant in this patient?

Accepted Answer

Progesterone

Question 13

Which of the following best describes the role of colposcopy in the management of abnormal cervical cytology?

Accepted Answer

To visually assess the cervix, take biopsies for diagnosis, and guide further treatment and management.

Question 14

Which of the following cell types is most likely to be seen in a cytology sample from a postmenopausal woman?

Accepted Answer

Parabasal cells

Question 15

A cytology sample shows a dense basophilic staining ball with filaments, and the patient has an intrauterine device (IUD). Which organism is most likely present?

Accepted Answer

Actinomyces-like organisms

Question 16

Which of the following is a characteristic feature of glandular dyskaryosis in cervical cytology?

Accepted Answer

Oval nuclei with nuclear enlargement, hyperchromasia, and coarse chromatin pattern.

Question 17

Which of the following best explains why the transformation zone is the most important area to sample during cervical screening?

Accepted Answer

It is the site where most cervical cancers and pre-cancerous lesions develop due to active metaplasia.

Question 18

A cytology sample from a woman with herpes simplex virus infection is most likely to show which of the following features?

Accepted Answer

Nuclear enlargement, ground glass appearance, and red inclusion bodies.

Question 19

Which of the following best describes the effect of oestrogen on the cervical epithelium?

Accepted Answer

Promotes growth, thickening, and maturation of squamous epithelium, resulting in many superficial cells.
