Deck 38: Genital Infections and Sexually Transmitted Diseases

Question 1

What test is sufficient for a diagnosis of Neisseria gonorrhea in men?

A) Culture
B) Gram stain
C) Enzyme immunoassay (EIA)
D) Radioimmunoassay (RIA)

Answer 1

B
The Gram stain is a sensitive,fast,and cheap tool for diagnosing gonorrhea in men.Gram stain of the penile exudates shows characteristic and diagnostic gram-negative intracellular diplococci in granulocytes.In symptomatic men,the Gram stain has a sensitivity of 90% to 95% and the specificity is over 95%.

Question 2

What is a symptom for secondary syphilis?

A) Chancre
B) Purulent discharge
C) Petechiae
D) Perianal condylomata-lata

Answer 2

D
A result of secondary syphilis is the appearance of condylomata-lata,which are mucoid,fleshy,wartlike growths.These lesions often occur in the perianal region but can occur in other moist regions of the body.

Question 3

What is the infective particle of Chlamydia?

A) Elementary body
B) Initial body
C) Negri body
D) Entire Chlamydia organism

Answer 3

A
The infective particle is the elementary body,which is the metabolically inert form of the organism.

Question 4

Why are there so many cases of genital herpes in the Unites States?

A) Condoms cannot prevent spread.
B) No protection is available.
C) Lesions shed when asymptomatic.
