Pathophysiology Q&A with Rationale |
Portage Learning
1. Which of the following describes the pathophysiology of Polycystic Ovary Syndrome
(PCOS)?
A. Hyperandrogenism and insulin resistance leading to follicular arrest
B. Excessive estrogen production leading to endometrial thinning
C. A primary deficiency in Luteinizing Hormone (LH) secretion
D. Autoimmune destruction of the ovarian follicles
Correct Answer: A
Rationale: PCOS is characterized by a state of hyperandrogenism and often involves
systemic insulin resistance. High levels of insulin can stimulate androgen production from
the ovaries, which interferes with the normal maturation of follicles. This leads to the
characteristic ‘cysts’ which are actually immature follicles that have failed to ovulate.
2. A patient presents with a firm, painless chancre on the genitalia. This clinical finding is
most characteristic of which stage of Syphilis?
A. Primary Stage
B. Latent Stage
C. Secondary Stage
,D. Tertiary Stage
Correct Answer: A
Rationale: Primary syphilis is characterized by the appearance of a single, painless sore
called a chancre at the site of infection. This sore typically appears about 3 weeks after
exposure and will heal without treatment, though the infection remains in the body. If
untreated, the disease will progress to the secondary stage involving a systemic rash.
3. What is the primary mechanism responsible for the symptoms observed in Benign Prostatic
Hyperplasia (BPH)?
A. Compression of the urethra by the enlarging prostate gland
B. Malignant transformation of the prostatic epithelium
C. Inflammation of the seminal vesicles
D. Decreased production of dihydrotestosterone (DHT)
Correct Answer: A
Rationale: BPH involves the non-cancerous proliferation of prostate cells, which causes
the gland to enlarge over time. As the prostate grows, it physically constricts the prostatic
urethra, leading to obstructive urinary symptoms. Common manifestations include a weak
urinary stream, hesitancy, and incomplete bladder emptying.
4. Which condition is considered a medical emergency due to the risk of ischemia and
necrosis of the testicle?
A. Hydrocele
, B. Testicular Torsion
C. Varicocele
D. Spermatocele
Correct Answer: B
Rationale: Testicular torsion occurs when the spermatic cord twists, cutting off the blood
supply to the testicle. This condition causes sudden, severe pain and requires immediate
surgical intervention to salvage the organ. Delayed treatment typically results in infarction
and permanent loss of the affected testicle.
5. Endometriosis is defined by which of the following pathological processes?
A. Hyperplasia of the endometrial lining within the uterus
B. The presence of endometrial tissue outside the uterine cavity
C. Infection of the fallopian tubes and ovaries
D. Excessive sloughing of the uterine lining during menses
Correct Answer: B
Rationale: Endometriosis occurs when functional endometrial tissue is found at ectopic
sites, most commonly the pelvic peritoneum and ovaries. This tissue responds to hormonal
changes during the menstrual cycle, leading to internal bleeding, inflammation, and pain.
Over time, it can cause the formation of dense adhesions and significant scarring in the
pelvic region.
