Pathophysiology Q&A with Rationale |
Portage Learning
1. Which of the following describes the pathophysiology of Polycystic Ovary Syndrome
(PCOS)?
A. A decrease in luteinizing hormone (LH) leading to ovarian atrophy.
B. Retrograde menstruation causing endometrial tissue to grow on ovaries.
C. Hyperinsulinemia and androgen excess resulting in follicular arrest.
D. A primary deficiency in estrogen production by the adrenal glands.
Correct Answer: C
Rationale: Polycystic Ovary Syndrome is primarily characterized by hyperinsulinemia and
excess androgen production. These hormonal imbalances interfere with the normal
maturation of follicles, leading to follicular arrest and the formation of small cysts. This
condition often results in secondary symptoms such as hirsutism, acne, and metabolic
disturbances.
2. A patient presents with dysmenorrhea, dyspareunia, and infertility. These symptoms are
most characteristic of which condition?
A. Bacterial Vaginosis
B. Endometrial Cancer
,C. Polycystic Ovary Syndrome
D. Endometriosis
Correct Answer: D
Rationale: Endometriosis occurs when functional endometrial tissue is found outside the
uterus, most commonly on the pelvic peritoneum or ovaries. The classic triad of symptoms
includes painful menstruation (dysmenorrhea), painful intercourse (dyspareunia), and
difficulty conceiving. This ectopic tissue responds to hormonal changes during the
menstrual cycle, causing localized inflammation and scarring.
3. In Benign Prostatic Hyperplasia (BPH), the primary clinical manifestations are a result of:
A. Compression of the prostatic urethra.
B. Systemic inflammatory response to testosterone.
C. Metastatic spread to the bladder wall.
D. Obstruction of the ureters by enlarged seminal vesicles.
Correct Answer: A
Rationale: Benign Prostatic Hyperplasia involves the non-malignant growth of the
prostate gland, which surrounds the male urethra. As the gland enlarges, it compresses the
prostatic urethra, leading to obstructive urinary symptoms such as weak stream and
hesitancy. If left untreated, the increased pressure can lead to bladder hypertrophy and
eventually kidney damage.
, 4. Which diagnostic test is considered the most specific screening tool for early detection of
prostate cancer?
A. Urine Culture and Sensitivity
B. Complete Blood Count (CBC) with differential
C. Computed Tomography (CT) of the Pelvis
D. Prostate-Specific Antigen (PSA) and Digital Rectal Exam (DRE)
Correct Answer: D
Rationale: Prostate cancer screening typically involves a combination of the Prostate-
Specific Antigen (PSA) blood test and a Digital Rectal Exam (DRE). While PSA is not entirely
specific to cancer, elevations combined with a hard or irregular nodule found during a DRE
warrant further investigation. Early detection through these methods is critical for
improving survival rates in male patients.
5. Which stage of syphilis is characterized by the appearance of a painless chancre at the site
of inoculation?
A. Latent Stage
B. Secondary Stage
C. Primary Stage
D. Tertiary Stage
Correct Answer: C
