Questions and Answers
- 1.
If a woman acquires an HPV infection which goes away after four months, is she protected from getting another episode of HPV infection again?
- 2.
If a woman acquires an infection from a high-risk type of HPV, does it mean that she will develop cancer?
- 3.
Genital HPV is the most common sexually transmitted infection in the world.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Genital HPV is indeed the most common sexually transmitted infection in the world. This is supported by extensive research and data from various sources, including the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC). HPV, or human papillomavirus, is highly prevalent and can be transmitted through sexual contact. It is estimated that around 80% of sexually active individuals will contract HPV at some point in their lives. Therefore, the statement "Genital HPV is the most common sexually transmitted infection in the world" is true.Rate this question:

70% of newly acquired genital HPV infections clear within one year.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
70% of newly acquired genital HPV infections clear within one year. This means that the majority of people who contract genital HPV will naturally clear the infection within 12 months without any medical intervention. Therefore, the statement is true.Rate this question:

The three functional coding regions of the human papillomavirus (HPV) are ____________, ____________ and____________. Name one of them.
Correct Answer
E
L
LCRExplanation
The three functional coding regions of the human papillomavirus (HPV) are E, L, and LCR. These regions are responsible for encoding various proteins and regulatory elements that are essential for the virus's replication and infection process. The E region encodes early proteins involved in viral DNA replication and transcriptional regulation. The L region encodes late proteins that form the viral capsid. The LCR region, also known as the long control region, contains regulatory elements that control the expression of viral genes.Rate this question:

The two major oncoproteins in HPV which are significant in high-risk HPV and its relation with cervical cancer are ___________________ and __________________. Name one of them.
Correct Answer
E6
E7Explanation
The two major oncoproteins in HPV that are significant in high-risk HPV and its relation with cervical cancer are E6 and E7. These oncoproteins are responsible for promoting cell growth and inhibiting cell death, leading to the development of cervical cancer. They interact with various cellular proteins, including tumor suppressor proteins, to disrupt normal cell functions and promote the survival and proliferation of infected cells.Rate this question:

Which layer of epithelium is the only tissue in which low risk HPV types can replicate?
- A.
Stratum corneum
- B.
Stratum granulosum
- C.
Stratum spinosum
- D.
Stratum basale
Correct Answer
D. Stratum basaleExplanation
HPV infection is limited to the basal cells of stratified epithelium, the only tissue in which they replicate.Rate this question:

- 11.
Which lesions are most likely associated with low-risk types of genital HPV?
- A.
Plantar warts
- B.
Flat warts
- C.
Respiratory papillomatosis
- D.
CIN3
Correct Answer
C. Respiratory papillomatosisExplanation
Plantar warts and flat warts are non-genital types of HPV. CIN 3 is caused by genital HPV of the high-risk type. Genital HPV types 6 and 11 can cause a rare condition known as recurrent respiratory papillomatosis, in which warts form on the larynx or other areas of the respiratory tract. HPV is acquired through oral-genital sexual contact, or when a mother with genital warts passes it to her baby during childbirth.Rate this question:

- C.
50%
- D.
30%
Correct Answer
A. 90%Explanation
90% of individuals infected with high-risk HPV infections clear the viral infection within two years.Rate this question:

Which of the following is considered a high-grade lesion that may regress spontaneously in 40 percent of women?
- A.
CIN1
- B.
CIN2
- C.
CIN3
- D.
CIS
Correct Answer
B. CIN2Explanation
CIN2 is considered a high-grade lesion that may regress spontaneously in 40 percent of women.Rate this question:

- B.
Type 18
- C.
Type 31
- D.
Type 45
Correct Answer
D. Type 45Explanation
HPV Type 45 is a high-risk HPV type which is strongly associated with adenocarcinoma, a less common but aggressive cancer arising from the endocervical glandular epithelium.Rate this question:
