Accepted Answer

Erection requires the release of nitrous oxide into the corpus cavernosum during sexual stimulation.

Question 2

A patient diagnosed with a micropenis must be evaluated for&#10;A) endocrine disorders.&#10;B) vascular abnormalities.&#10;C) female sex assignment.&#10;D) epispadias.

Accepted Answer

Penile development and growth are both testosterone-dependent.Patients with micropenis must be evaluated for endocrine abnormalities.Micropenis has been shown to be related to vascular disorders.Female sex assignment is considered only after treatment failure.Epispadias is an abnormality of the urethral opening and unrelated to micropenis.

Question 3

The pathology report for a patient with penile cancer has this statement: The tumor involves the shaft of the penis.The cancer is at what stage?&#10;A) Stage I&#10;B) Stage II&#10;C) Stage III&#10;D) Stage IV

Accepted Answer

Penile carcinoma is staged as follows: Stage I: The lesion is limited to the glans or foreskin.Stage II: The tumor involves the shaft of the penis.Stage III: The inguinal nodes are involved,but the lesion is operable.Stage IV: Disseminated disease.

Question 4

The condition in which the urethra opens on the dorsal aspect of the penis is known as&#10;A) hypospadias.&#10;B) urethral fistula.&#10;C) epispadias.&#10;D) priapism.

Accepted Answer

In epispadias,the urethra opens on the dorsal aspect of the penis at a point proximal to the glans.In hypospadias,the urethral meatus is located on the ventral undersurface of the penis or on the perineum.A urethral fistula is a failure of the urorectal septum to develop completely.Priapism is defined as a painful,persistent erection.

Question 5

A progressive decrease in the force of the urinary stream,dribbling of urine,and difficulty initiating the urinary stream are characteristic of&#10;A) prostatitis.&#10;B) urinary calculi.&#10;C) bladder carcinoma.&#10;D) prostatic enlargement.

Accepted Answer

A decrease in the force of the urinary stream,hesitancy or difficulty in initiating a urinary stream,and interruption of the stream may occur with prostatic enlargement.Prostatitis presents with frequency,urgency,and dysuria.Urinary calculi cause sudden,severe onset of pain.Bladder carcinoma is usually characterized by hematuria,painful or frequent urination,and abdominal or back pain.

Question 6

Sudden,severe testicular pain is indicative of&#10;A) prostatitis.&#10;B) testicular cancer.&#10;C) testicular torsion.&#10;D) epididymitis.

Accepted Answer

A twisting of the spermatic cord with subsequent testicular ischemia and infarction,testicular torsion,commonly presents with sudden onset of severe testicular pain.Prostatitis is manifested by a tender,swollen prostate.Testicular cancer has a slower,less dramatic presentation.Epididymitis can resemble testicular torsion,but usually presents with an enlarged,reddened,and tender scrotum,as opposed to a sudden onset of severe pain.

Question 7

A patient presenting with a urethral stricture may experience (Select all that apply.)&#10;A) decreased urinary stream.&#10;B) urethral discharge.&#10;C) infection.&#10;D) urine retention.&#10;E) inability to retract the glans of the penis.

Accepted Answer

Signs and symptoms of urethral stricture include decreased urinary stream,urethral discharge,infection,and urine retention.Phimosis,the inability to retract the glans of the penis,is an unrelated condition.
