1. A 65-year-old Caucasian male has a firm, nontender, symmetrically enlarged prostate gland
on examination. His PSA is 3.9 ng/mL. His PSA level is influenced by:
A) race only.
B) age and race.
C) prostate volume.
D) race, age, and volume.
Correct Answer: D) race, age, and volume.
Rationale: PSA values may be specific for age and race and are influenced by the volume of
prostate tissue present. The greater the amount of prostate tissue present, the greater the PSA
value.
2. The first sign that a male child is experiencing sexual maturation is:
A) increase in testicular size.
B) enlargement of the scrotum.
C) increase in length of the penis.
D) scrotal and penile changes.
Correct Answer: A) increase in testicular size.
Rationale: A male in Tanner Stage II will have an increase in testicular volume from 1.5 mL
or less to up to 6 mL. The skin on the scrotum will begin to thin, redden, and enlarge.
3. Which of the following results in a clinically INSIGNIFICANT increase in the prostate-
specific antigen (PSA)?
A) Digital rectal exam
B) Ejaculation
,C) Prostatitis
D) Prostate biopsy
Correct Answer: A) Digital rectal exam
Rationale: Digital rectal exam (DRE) leads to a clinically insignificant increase of 0.26-0.4
ng/mL for about 48-72 hours afterwards. Prostate biopsy increases the PSA about 8 ng/mL
for up to 4 weeks.
4. Hesselbach's triangle forms the landmark for:
A) inguinal hernia.
B) femoral hernia.
C) abdominal hernia.
D) umbilical hernia.
Correct Answer: A) inguinal hernia.
Rationale: Direct inguinal hernias occur through Hesselbach's triangle. The inguinal
ligament, the rectus muscle, and the epigastric vessels form the triangle.
5. Noninfectious epididymitis is common in:
A) soccer players.
B) truck drivers.
C) marathon runners.
D) men who wear boxer-style underwear.
Correct Answer: B) truck drivers.
Rationale: Noninfectious epididymitis occurs when there is reflux of urine into the
epididymis from the ejaculatory ducts and vas deferens. This can occur if males spend a lot of
time sitting.
, 6. Lab Results Prostate-Specific Antigen- 9/2014- 3.2 ng/mL, 09/2015- 3.8ng/mL, 09/2016-
4.2ng/mL. The following PSA levels have been observed in a patient. What conclusion can be
made following these annual readings?
A) They are all within normal range.
B) None are within normal range.
C) There is a steady increase that is worrisome.
D) There is a steady increase but not worrisome.
Correct Answer: C) There is a steady increase that is worrisome.
Rationale: A steady increase in PSA over time, even if values are within the normal range, is
worrisome and warrants further evaluation.
7. A 50-year-old male experiences difficulty achieving and maintaining an erection. This
condition is MOST likely a result of:
A) Obstructive sleep apnea
B) Cardiovascular disease
C) An endocrine disorder
D) Benign prostatic hypertrophy
Correct Answer: B) Cardiovascular disease
Rationale: Erectile dysfunction is often an early indicator of underlying cardiovascular
disease. The vascular etiology involves endothelial dysfunction and reduced blood flow to the
corpora cavernosa.
8. A 53-year-old male is diagnosed with benign prostatic hyperplasia (BPH). He takes
sildenafil (Viagra) for erectile dysfunction. The medication that is LEAST likely to interact
with Viagra is:
A) Nitroglycerin
B) Alpha-blockers
