Question 1

A long asymptomatic latent phase is characteristic of which of the following sexually transmitted infections?&#10;A) Gonorrhea&#10;B) Syphilis&#10;C) Chlamydia&#10;D) Hepatitis B

Accepted Answer

The secondary stage of syphilis is self-limiting and is followed by a latent phase in which no symptoms are present.Infection with gonorrhea is not associated with a latent phase.After invasion of the mucosa by Chlamydia during sexual contact,a painless lesion appears on the genitalia after a 1- to 3-week incubation period.Hepatitis B infection is not characterized by a long latent phase.

Question 2

The first choice of treatment for the management of syphilis is&#10;A) penicillin G.&#10;B) doxycycline.&#10;C) antiviral agents.&#10;D) antimicrobial agents.

Accepted Answer

Penicillin G is the first choice for the management of syphilis.If the affected person is allergic to penicillin,tetracycline or doxycycline is given.Doxycycline is indicated in the treatment of lymphogranuloma venereum.Antiviral agents are not indicated in the treatment of syphilis.Antimicrobial agents would be utilized in treating gonorrhoeae.

Question 3

What systemic infections are potentially transmitted by sexual contact? (Select all that apply.)&#10;A) Cytomegalovirus&#10;B) Hepatitis A&#10;C) Hepatitis B&#10;D) HIV&#10;E) Herpes simplex virus

Accepted Answer

Cytomegalovirus is a systemic infection that may be transmitted by sexual contact.Hepatitis A and B are both systemic infections that may be transmitted through sexual contact.Human immunodeficiency virus can be transmitted through sexual contact.Herpes simplex virus is not a systemic infection.

Question 4

The organism most commonly associated with pelvic inflammatory disease is&#10;A) Neisseria gonorrhoeae.&#10;B) Treponema pallidum.&#10;C) Escherichia coli.&#10;D) Pseudomonas.

Accepted Answer

Pelvic inflammatory disease is usually the result of acute salpingitis caused by gonococcal or chlamydial infection that has extended into nearby pelvic tissue.Syphilis is acquired when T.pallidum penetrates intact mucous membrane or abraded skin during sexual contact.Escherichia coli is not generally associated with pelvic inflammatory disease.Pelvic inflammatory disease is not associated with Pseudomonas infection.

Question 5

Which infection can be a risk factor for cervical cancer?&#10;A) Human papillomavirus&#10;B) Molluscum contagiosum&#10;C) Granuloma inguinale&#10;D) Chancroid

Accepted Answer

Condylomata acuminata,or genital warts,are associated with infection by human papillomavirus.Persistent human papillomavirus infection is an important risk factor for cervical cancer.Molluscum contagiosum is associated with infection by a poxvirus.The disease is usually asymptomatic and self-limiting.Granuloma inguinale is caused by an intracellular bacterium.The initial papule is painless and subsequently ulcerates into a growing granulomatous ulcer resembling a tumor.Chancroid is caused by infection with an anaerobic bacillus.Lesions resemble those of syphilis; however,the lesions of syphilis are painless.

Question 6

Which of the following infections is asymptomatic and self-limited and does not require therapy?&#10;A) Syphilis&#10;B) Nongonococcal cervicitis&#10;C) Gonorrhea&#10;D) Molluscum contagiosum

Accepted Answer

Molluscum contagiosum is a viral skin disease caused by a member of the poxvirus family.The disease is usually asymptomatic,tends to be self-limiting,and lasts on average 2 years.Treatment is required for syphilis infection.Nongonococcal cervicitis requires treatment because it may result in pelvic inflammatory disease.Infection related to gonorrhea does require treatment.

Question 7

The Centers for Disease Control estimate that there are ________ new sexually transmitted infections every year.&#10;A) 300,000&#10;B) 1.3 million&#10;C) 19 million&#10;D) 17 billion

Accepted Answer

The CDC estimates that there are 19 million new infections every year.More than 300,000 cases are related to gonococcal infection.1.3 million sexually transmitted diseases are related to chlamydia infections.It is estimated that sexually transmitted infections cost the health care system $17 billion every year.

Question 8

The initial incubation period of syphilis lasts for&#10;A) 2 to 3 days.&#10;B) 10 to 90 days.&#10;C) 3 to 6 weeks.&#10;D) 40 years.

Accepted Answer

The initial incubation period of syphilis is 10 to 90 days.The initial incubation period is more than 2 to 3 days with syphilis.Untreated chancres usually resolve in 3 to 6 weeks without treatment.The latent stage of syphilis may last more than 40 years.

Question 9

Transmission of Chlamydia during birth may result in ________,or infection of the eyes in the newborn.&#10;A) neonatal jaundice&#10;B) ophthalmia neonatorum&#10;C) neonatal conjunctivitis&#10;D) erythema neonatorum

Accepted Answer

Transmission of chlamydia during birth may result in ophthalmia neonatorum,or infection of the eyes in the newborn.Neonatal jaundice is not associated with exposure to chlamydia at childbirth.Transmission of Chlamydia does not cause neonatal conjunctivitis.Erythema neonatorum is not a condition associated with Chlamydia.

Question 10

Herpes lesions are fluid-filled vesicles that appear __________days after infection.&#10;A) 1 to 2&#10;B) 3 to 7&#10;C) 7 to 10&#10;D) 10 to 14

Accepted Answer

Genital infection with HSV type 2 is manifested by the appearance of fluid-filled vesicles after a 3- to 7-day incubation period.Herpes lesions do not appear until at least 3 days after infection.Lesions generally crust and heal within 10 days.The incubation period after infection with herpes is 3 to 7 days.

Question 11

Central nervous system degeneration,blindness,and paresis are associated with untreated&#10;A) HSV.&#10;B) LGV.&#10;C) syphilis.&#10;D) gonorrhea.

Accepted Answer

The answer of Central nervous system degeneration,blindness,and paresis are associated...

Question 12

A painless ulceration called a chancre is a lesion associated with infection by&#10;A) human papillomavirus.&#10;B) N. gonorrhoeae.&#10;C) C. trachomatis.&#10;D) T. pallidum.

Accepted Answer

The answer of A painless ulceration called a chancre is...

Question 13

A 23-year-old male presents with urethritis,dysuria,and purulent urethral discharge.The suspected diagnosis would be&#10;A) gonorrhea.&#10;B) urinary tract infection.&#10;C) Chlamydia.&#10;D) syphilis.
