MULTIPLE CHOICE
1. The organism most commonly associated with pelvic inflammatory disease is
a. Neisseria gonorrhoeae.
b. Treponema pallidum.
c. Escherichia coli.
d. Pseudomonas.
ANS: A
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.
REF: Pg. 689
2. A long asymptomatic latent phase is characteristic of which of the following sexually transmitted infections?
a. Gonorrhea
b. Syphilis
c. Chlamydia
d. Hepatitis B
ANS: B
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.
REF: Pgs. 690-691
3. A painless ulceration called a chancre is a lesion associated with infection by
a. human papillomavirus.
b. N. gonorrhoeae.
c. C. trachomatis.
d. T. pallidum.
ANS: D
The primary phase of syphilis begins with the formation of a chancre, a painless, ulcerative lesion that arises at the original portal of
entry. Human papillomavirus is not associated with chancre lesions. In gonorrhea, chancres are not present. The symptoms of
infection with Chlamydia are generally less severe than those of syphilis and are not evidenced by a chancre lesion.
REF: Pg. 690
4. Which infection can be a risk factor for cervical cancer?
a. Human papillomavirus
b. Molluscum contagiosum
c. Granuloma inguinale
d. Chancroid
ANS: A
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.
REF: Pgs. 693-694
5. Which of the following infections is asymptomatic and self-limited and does not require therapy?
a. Syphilis
b. Nongonococcal cervicitis
c. Gonorrhea
d. Molluscum contagiosum
ANS: D
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.
