NSG 6320 AGNP Board Exam – Sexually
Transmitted Diseases Assessment Exam
1. Question:
Which is NOT a type of diagnostic test for human immunodeficiency virus
(HIV)?
Antibody test
Combination antibody and antigen test
Cluster of differentiation 4 (CD4) Correct
Nucleic acid tests (NATs)
Explanation:
Cluster of differentiation 4 (CD4) is a glycoprotein found on the surface of
immune cells such as T-helper cells, monocytes, macrophages, and dendritic
cells. CD4 counts are most often assessed after the diagnosis of human
immunodeficiency virus (HIV) has been made. Tests for HIV include the
antibody test, combination test, and nucleic acid tests. The CD4 count
results, along with an HIV viral load, are used to evaluate the immune
system of a person diagnosed with HIV infection and to monitor effectiveness
of antiretroviral treatment (ART or ARV), also called highly active
antiretroviral therapy (HAART).
2. Question:
Which sexually transmitted disease (STD) is known as a ‘silent’ infection and
often lacks abnormal physical examination findings?
Syphilis
Chlamydia Correct
Trichomoniasis
Bacterial vaginosis
Explanation:
Chlamydia is known as a ‘silent’ infection because most infected people are
asymptomatic and lack abnormal physical examination findings. A person
with primary syphilis generally has chancres at the original site of infection.
Symptoms of secondary syphilis include skin rash, swollen lymph nodes, and
fever. Tertiary syphilis is associated with severe neurological problems.
Trichomoniasis causes burning with urination, as well as foul smelling vaginal
or penile discharge. Bacterial vaginosis (BV) causes a thin white or gray
vaginal discharge, burning in the vagina, and a strong fish-like odor in
women.
3. Question:
What is the gold standard method for diagnosing bacterial vaginosis (BV)?
Bimanual examination
, Urine culture
Gram stain Correct
Rectal examination
Explanation:
A Gram stain (considered the gold standard laboratory method for
diagnosing bacterial vaginosis) is used to determine the relative
concentration of lactobacilli (i.e., long gram-positive rods), gram-negative
and gram-variable rods and cocci (i.e., G.
vaginalis, Prevotella, Porphyromonas, and peptostreptococci), and curved
gram-negative rods (i.e., Mobiluncus) characteristic of bacterial vaginosis
(BV).
4. Question:
What is the sexually transmitted disease (STD) caused by infection with
Haemophilus ducreyi and characterized by painful necrotizing genital ulcers?
Herpes simplex virus
Chancroid Correct
Syphilis
Herpes zoster
Explanation:
Chancroid is a bacterial sexually transmitted disease (STD) caused by an
infection with Haemophilus ducreyi. It is characterized by painful necrotizing
genital ulcers that may be accompanied by inguinal lymphadenopathy.
Herpes simplex is caused by the herpes simplex virus-type 1 (HSV-1);
syphilis is caused by a spirochete called Treponema pallidum; and herpes
zoster is caused by varicella zoster virus.
5. Question:
Which of the following symptoms would be a clinical manifestation noted
during the tertiary stage of syphilis?
A single painless lesion, chancre, on the genital area
Absence of symptoms
Rash marked by red or reddish-brown, penny-sized lesions over the palms
and soles
Poor muscle coordination Correct
Explanation:
Syphilis is a sexually transmitted bacterial infection that involves the
genitals, skin and mucous membranes. Signs and symptoms occur in four
stages: primary, secondary, latent, and tertiary. Primary stage symptoms
include a single painless lesion, chancre, on the genitals, rectum, tongue, or
lip and enlarged lymph nodes. In the secondary stage, the rash is marked by
red or reddish-brown, penny-sized lesions over any part of the body including
