Pathophysiology Q&A with Rationale |
Portage Learning
1. A 65-year-old male presents with urinary hesitancy, frequency, and a weak urinary stream.
Digital rectal examination reveals a smooth, enlarged prostate. Which condition is most
likely?
A. Benign Prostatic Hyperplasia (BPH)
B. Prostate Cancer
C. Acute Prostatitis
D. Urethral Stricture
Correct Answer: A
Rationale: Benign Prostatic Hyperplasia (BPH) is characterized by a non-malignant
enlargement of the prostate gland that compresses the urethra. Clinical manifestations
typically include obstructive symptoms such as hesitancy and a decreased stream. The
smooth nature of the prostate on examination helps differentiate it from the nodular
consistency found in malignancy.
2. Which of the following is a key pathophysiological feature of Polycystic Ovary Syndrome
(PCOS)?
A. Excessive estrogen production alone
,B. Hyperinsulinemia and insulin resistance
C. Decreased Luteinizing Hormone (LH) levels
D. Increased Follicle Stimulating Hormone (FSH) levels
Correct Answer: B
Rationale: PCOS is a complex endocrine disorder often involving hyperinsulinemia and
insulin resistance. Insulin resistance stimulates the ovaries to produce excess androgens,
leading to symptoms like hirsutism and acne. This condition also typically presents with an
elevated LH to FSH ratio, which contributes to anovulation.
3. A patient is diagnosed with endometriosis. Which statement best describes the
pathophysiology of this condition?
A. Infection of the endometrial lining after childbirth
B. Overgrowth of the endometrium within the uterine cavity
C. Presence of functional endometrial tissue outside the uterus
D. Malignant transformation of the uterine smooth muscle
Correct Answer: C
Rationale: Endometriosis occurs when functional endometrial tissue is found at sites
outside of the uterine cavity. This ectopic tissue responds to monthly hormonal cycles,
leading to bleeding and inflammation within the pelvic cavity. Over time, this process can
cause significant pain, scarring, and adhesions, which may lead to infertility.
, 4. Which organism is the most common cause of Pelvic Inflammatory Disease (PID)?
A. Staphylococcus aureus
B. Neisseria gonorrhoeae
C. Escherichia coli
D. Treponema pallidum
Correct Answer: B
Rationale: Pelvic Inflammatory Disease is frequently caused by sexually transmitted
organisms such as Neisseria gonorrhoeae and Chlamydia trachomatis. These pathogens
ascend from the vagina through the cervix to infect the uterus and fallopian tubes. If left
untreated, the resulting inflammation can cause permanent damage to the reproductive
organs and increase the risk of ectopic pregnancy.
5. What is the primary risk factor associated with the development of cervical cancer?
A. Early menopause
B. Nulliparity
C. Use of oral contraceptives
D. Human Papillomavirus (HPV) infection
Correct Answer: D
Rationale: Infection with high-risk strains of Human Papillomavirus (HPV), particularly
types 16 and 18, is the primary driver of cervical dysplasia and cancer. HPV DNA integrates
