Questions and Answers with Explanations
A 50-year-old male comes to the nurse practitioner clinic for evaluation. He complains of chills, pelvic pain,
and dysuria. He should be diagnosed with (VS in image):
acute bacterial prostatitis.
chronic bacterial prostatitis.
urinary tract infection.
nonbacterial prostatitis.
A.
Acute bacterial prostatitis should always be considered first in a male patient who presents with these
symptoms. He may have cloudy urine and symptoms of obstruction, like dribbling. Chronic bacterial
prostatitis presents with a more subtle presentation, such as frequency, urgency, and rarely, low-grade
fever. Urinary tract infection is far less common in men than women and is usually associated with anal
intercourse or being uncircumcised. Nonbacterial prostatitis presents like chronic prostatitis except that
urine and prostate secretion cultures are negative.
Noninfectious epididymitis is common in:
soccer players.
truck drivers. Correct
marathon runners.
men who wear boxer-style underwear.
B.
Noninfectious epididymitis occurs when there is reflux of urine into the epididymis from the ejaculatory
ducts and vas deferens. This can cause ductal obstruction and acute inflammation without infection. This can
, occur if males spend a lot of time sitting. Truck drivers are particularly susceptible because they spend
many uninterrupted hours sitting when they are driving. Other typical risk factors are vigorous exercise that
involve heavy lifting or upper body workouts; especially sit-ups or abdominal crunches.
The following PSA levels have been observed in a patient. What conclusion can be made following these
annual readings (SEE IMAGE)
They are all within the normal range.
None are within the normal range.
There is a steady increase that is worrisome.
There is a steady increase but not worrisome.
C.
Evaluation of PSA velocity generally requires three serial readings over a 12-24 month period. The PSA
velocity (the rate of PSA change over time), is concerning. A PSA velocity > .35 ng/mL per year is associated
with high risk of death from prostate cancer. This patient should have prostate biopsy by a urologist.
A 71-year-old male patient is taking dutasteride (Avodart), a 5-alpha-reductase inhibitor. What effect might
this have on his PSA level?
It will increase.
It will decrease.
There is no predictable change.
There will be a clinically insignificant increase.
B.
The 5-alpha-reductase inhibitors like dutasteride and finasteride will reduce PSA levels will sustain this
reduction as long as the medication is taken. This class of medication interferes with the prostatic
intracellular androgen response mechanism.
A patient with testicular torsion will have a:
positive cremasteric reflex on the affected side.
