question
What term is used to identify a condition in which the foreskin cannot be retracted over the glans penis? a. Paraphimosis b. Priapism c. Prephimosis d. Phimosis
answer
ANS: D Phimosis is the only term used to identify the condition in which the foreskin cannot be retracted back over the glans.
question
What term is used to identify a fibrotic condition that causes lateral curvature of the penis during erection, which is associated with a local vasculitis-like inflammatory reaction and decreased tissue oxygenation? a. Phimosis b. Lateral phimosis c. Lateral paraphimosis d. Peyronie disease
answer
ANS: D Peyronie disease (bent nail syndrome) is a fibrotic condition of the tunica albuginea of the penis, resulting in varying degrees of curvature and sexual dysfunction (see Figure 25-2). Although the exact cause is unknown, a local vasculitis-like inflammatory reaction occurs and decreased tissue oxygenation results in fibrosis and calcification. Peyronie disease is the only term used to identify the pathophysiologic condition described.
question
What term is used to identify an inflammation of the glans penis? a. Glanitis c. Priapism b. Balanitis d. Hydrocelitis
answer
ANS: B Balanitis is the only term used to identify an inflammation of the glans penis

Cryptorchidism can be defined as which of the following? a. Normal developmental state of the testes b. Abnormal state in which the testes are overdeveloped c. Lack of scrotum d. Testicular maldescent
answer
ANS: D Cryptorchidism is a condition of testicular maldescent, the only option that accurately defines cryptorchidism.
question
What is the most common infectious cause of orchitis and one that usually affects postpubertal boys? a. Herpes b. Escherichia coli c. Mumps d. Cytomegalovirus
answer
ANS: C Of the options available, mumps is the most common infectious cause of orchitis and usually affects postpubertal boys.
question
The risk of which cancer is greater if the man has a history of cryptorchidism? a. Penile c. Prostate b. Testicular d. Epididymal
answer
ANS: B The risk of testicular cancer is 35 to 50 times greater in men with cryptorchidism or in those with a history of cryptorchidism than it is for the general male population. This is not true of the other options.
question
What are the clinical manifestations of testicular cancer? a. Firm, nontender testicular mass b. Painful, mobile, firm testicular mass c. Painful fluid-filled testicular mass d. Soft, nontender testicular mass
answer
ANS: A Of the options available, a firm, painless testicular enlargement is commonly identified as the first sign of testicular cancer.
question
How does the epididymis become infected? a. The pathogenic microorganisms ascend the vasa deferentia from an already infected urethra or bladder. b. The pathogenic microorganisms are attached to sperm that travel through the genital tract. c. The pathogenic microorganisms from the tunica vaginalis are transported to the epididymis. d. The pathogenic microorganisms from the prostate fluid ascend to the epididymis.
answer
ANS: A The pathogenic microorganisms usually reach the epididymis by ascending the vasa deferentia from an already infected urethra or bladder. Of the selections available, this is the only option that accurately describes how the epididymis becomes infected.
question
Symptoms of benign prostatic hyperplasia (BPH) are a result of which pathophysiologic condition? a. Infection of the prostate b. Obstruction of the urethra c. Ischemia of the urethra d. Compression of the urethra
answer
ANS: D BPH becomes problematic as prostatic tissue compresses the urethra, where it passes through the prostate. Of the selections available, only this option accurately describes the pathophysiologic condition behind the symptoms of BPH.
question
Which infection has clinical manifestations that include the sudden onset of malaise, low back pain, and perineal pain with high fever and chills, dysuria, nocturia, and urinary retention? a. Orchitis c. Epididymitis b. Balanitis d. Bacterial prostatitis
answer
ANS: D Bacterial prostatitis can exhibit common manifestations that include a sudden onset of malaise, low back and perineal pain, high fever (up to 40° C [104° F]), and chills, as well as dysuria, inability to empty the bladder, nocturia, and urinary retention. Myalgia and arthralgia also may occur. This selection is the only option that exhibits the symptoms described.
question
Priapism has been associated with the abuse of what substance? a. Marijuana c. Cocaine b. Alcohol d. Heroin
answer
ANS: C Of the options available, priapism has been associated with cocaine use.
question
Which age group should be targeted for testicular cancer education and screening? a. 15 to 35 year olds b. 20 to 45 year olds c. 30 to 55 year olds d. 45 to 70 year olds
answer
ANS: A Overall, testicular cancers are rare, yet they are the most common form of cancer in young men between the ages of 15 and 35 years.
question
What is the reason breast cancer in men has such a poor prognosis? a. Breast cancer is extremely aggressive in men. b. Treatment is usually delayed as a result of late detection. c. Chemotherapies are not as effective in men. d. Breast tumors tend to be small and hard to isolate.
answer
ANS: B Breast cancer is relatively uncommon in men, but it has a poor prognosis because men tend to delay seeking treatment until the disease is advanced. This selection is the only option that accurately identifies the reason breast cancer in men has a poor prognosis.
question
Which are clinical manifestations of male breast cancer? (Select all that apply.) a. Ulceration present on the breast b. Retraction of breast tissue c. Nipple discharge d. Palpable mass midline of the nipple e. Unilateral solid mass
answer
ANS: A, B, C, E The malignant male breast lesion is usually a unilateral solid mass located near the nipple. Because the nipple is commonly involved, crusting and nipple discharge are typical clinical manifestations. Other findings include skin retraction, ulceration of the skin over the tumor, and axillary node involvement.
question
Which statements are true regarding urethritis? (Select all that apply.) a. A purulent drainage may be present. b. A clear mucus-like discharge may be present. c. Symptoms include urethral tingling and itching or burning on urination. d. A 24-hour urine test is required to diagnose the disorder. e. Treatment includes appropriate antibiotic therapy.
answer
ANS: A, B, C, E Symptoms of urethritis include urethral tingling and itching or a burning sensation on urination (dysuria), frequency, and urgency. The individual may note a purulent or clear mucus-like discharge from the urethra. Nucleic acid detection amplification tests allow easy detection of Neisseria gonorrhoeae and Chlamydia trachomatis in first-void urine. Treatment consists of appropriate antibiotic therapy for infectious urethritis and an avoidance of future chemical or mechanical irritation.
question
Which statements are true regarding prostate cancer? (Select all that apply.) a. It ranks second to lung cancer as being most common among American men. b. A familial history of prostate cancer is a risk factor. c. Dietary habits seem to play a role in its development. d. African-American men have an increased risk for its development. e.
