NURS 231/NURS231 Module 10 V1 |
Pathophysiology Q&A with Rationale | Portage
Learning
1. A 65-year-old male presents with urinary hesitancy, a weak stream, and the sensation of
incomplete bladder emptying. Digital rectal examination (DRE) reveals a smooth, enlarged,
and non-tender prostate. Which of the following conditions is most likely responsible for
these symptoms?
A. Prostate cancer
B. Benign Prostatic Hyperplasia (BPH)
C. Acute prostatitis
D. Chronic prostatitis
Correct Answer: B
Explanation: Benign Prostatic Hyperplasia (BPH) is a non-malignant enlargement of the
prostate gland common in aging men. The enlargement compresses the prostatic urethra,
leading to obstructive voiding symptoms such as hesitancy and weak flow. The smooth,
non-tender enlargement noted on DRE differentiates it from the nodular consistency of
cancer or the tenderness of acute inflammation.
2. A clinician is reviewing the risk factors for testicular torsion in a 14-year-old patient. Which
anatomical anomaly most significantly increases the risk of this surgical emergency?
A. Bell-clapper deformity
,B. Cryptorchidism
C. Hydrocele
D. Varicocele
Correct Answer: A
Explanation: The bell-clapper deformity occurs when the tunica vaginalis abnormally
attaches to the spermatic cord, allowing the testis to rotate freely. This rotation leads to
twisting of the spermatic cord and subsequent ischemia of the testicle. Immediate surgical
intervention is required to prevent permanent tissue necrosis and loss of the testis.
3. A 28-year-old female presents with severe pelvic pain that worsens during menstruation
and painful intercourse. She has been unable to conceive for two years. Laparoscopic
evaluation reveals endometrial tissue implanted on the ovaries and peritoneum. What is the
most likely diagnosis?
A. Pelvic Inflammatory Disease (PID)
B. Polycystic Ovary Syndrome (PCOS)
C. Endometriosis
D. Adenomyosis
Correct Answer: C
Explanation: Endometriosis is characterized by the presence of functional endometrial
tissue outside the uterine cavity. This ectopic tissue responds to hormonal cycles, causing
,inflammation, pain, and scarring within the pelvic cavity. It is a leading cause of infertility
and chronic pelvic pain in reproductive-age women.
4. In the development of Polycystic Ovary Syndrome (PCOS), which underlying endocrine
abnormality is central to the pathophysiology of follicular arrest and hyperandrogenism?
A. Insulin resistance and hyperinsulinemia
B. Hyposecretion of Luteinizing Hormone (LH)
C. Excessive secretion of Follicle-Stimulating Hormone (FSH)
D. Hypoprolactinemia
Correct Answer: A
Explanation: Insulin resistance and the resulting hyperinsulinemia play a critical role in
the pathogenesis of PCOS by stimulating ovarian androgen production. High insulin levels
also decrease the production of sex hormone-binding globulin, further increasing free
testosterone levels. This hormonal imbalance leads to the characteristic symptoms of
hirsutism, acne, and ovulatory dysfunction.
5. A patient is diagnosed with secondary syphilis. Which of the following clinical findings is
most characteristic of this stage of the infection?
A. A painless chancre at the site of inoculation
B. Development of neurosyphilis symptoms
C. Formation of gummas in bone and skin
, D. A generalized maculopapular rash involving the palms and soles
Correct Answer: D
Explanation: Secondary syphilis occurs weeks to months after the primary chancre heals
and represents systemic dissemination of Treponema pallidum. The most common
manifestation is a symmetrical, non-itchy rash that frequently affects the palms of the
hands and soles of the feet. This stage may also involve lymphadenopathy, fever, and
mucous patches in the mouth.
6. Which organism is the most frequent cause of Pelvic Inflammatory Disease (PID), often
leading to tubal scarring and an increased risk of ectopic pregnancy?
A. Candida albicans
B. Neisseria gonorrhoeae
C. Gardnerella vaginalis
D. Treponema pallidum
Correct Answer: B
Explanation: Neisseria gonorrhoeae and Chlamydia trachomatis are the two most
common pathogens responsible for Pelvic Inflammatory Disease. These bacteria ascend
from the lower genital tract to the uterus and fallopian tubes, causing significant
inflammation. The resulting damage to the ciliated epithelium of the tubes increases the
risk for chronic pain, infertility, and ectopic pregnancy.
