Introduction
This examination covers essential concepts in endocrinology, reproductive health,
and urology. The questions are designed to assess understanding of
pathophysiology, clinical manifestations, diagnostic approaches, and treatment
modalities for conditions including thyroid disorders, gynecological conditions,
prostatitis, and benign prostatic hyperplasia. Each question includes a detailed
rationale to reinforce learning and clinical application.
SECTION 1: THYROID DISORDERS
1. A 68-year-old male presents with bilateral breast enlargement. Which of the
following is the most likely cause of this finding?
A. Testicular cancer
B. Aging-related gynecomastia
C. Prostate cancer
D. Hyperthyroidism
Answer: B. Aging-related gynecomastia
Rationale: Gynecomastia commonly occurs in aging males due to declining
testosterone levels relative to estrogen. Other causes include the neonatal period,
puberty (particularly in tall/overweight teenagers), and obesity. Testicular cancer,
prostate cancer, and hyperthyroidism are less common causes of gynecomastia.
,2. A 45-year-old female presents with fatigue, weight gain, and cold
intolerance. Laboratory testing reveals an elevated TSH. What is the most
likely diagnosis?
A. Graves' disease
B. Secondary hypothyroidism
C. Primary hypothyroidism
D. Subclinical hyperthyroidism
Answer: C. Primary hypothyroidism
Rationale: Primary hypothyroidism is characterized by elevated TSH due to
thyroid gland dysfunction. It affects approximately 85% more women than men.
Secondary hypothyroidism would present with low TSH due to pituitary
dysfunction. Graves' disease causes hyperthyroidism with suppressed TSH.
Subclinical hyperthyroidism would show low TSH with normal T4.
3. Which of the following laboratory findings is consistent with Hashimoto's
thyroiditis?
A. Low TSH
B. Elevated TSH
C. Normal TSH with low T4
D. Elevated T3 uptake
Answer: B. Elevated TSH
Rationale: Hashimoto's thyroiditis is an autoimmune destruction of the thyroid
gland leading to primary hypothyroidism, which manifests as elevated TSH. Low
TSH is seen in hyperthyroid states. Normal TSH with low T4 is not characteristic
of Hashimoto's. Elevated T3 uptake is associated with hyperthyroidism.
4. A patient is diagnosed with hypothyroidism and started on levothyroxine.
When should TSH be repeated to assess therapeutic response?
A. 1 week after initiation
B. 2 weeks after initiation
,C. 4-6 weeks after initiation
D. 3 months after initiation
Answer: C. 4-6 weeks after initiation
Rationale: TSH should be repeated 4-6 weeks after initiating levothyroxine therapy
to assess response. The target TSH level should be between 0.4-2 mIU/L. The
average maintenance dose is 1.6 mcg/kg/day. Shorter intervals would not allow
sufficient time for steady-state levels to be achieved.
5. A patient with Graves' disease is undergoing evaluation. Which of the
following autoimmune conditions is NOT associated with increased risk in this
patient?
A. Celiac disease
B. Type 2 diabetes mellitus
C. Pernicious anemia
D. Vitiligo
Answer: B. Type 2 diabetes mellitus
Rationale: Graves' disease is associated with increased risk of systemic
autoimmune conditions including Sjogren's syndrome, celiac disease, pernicious
anemia, Addison's disease, alopecia areata, vitiligo, type 1 diabetes mellitus (not
type 2), hypoparathyroidism, myasthenia gravis, and cardiomyopathy. Type 2
diabetes is not an autoimmune condition and is not associated with Graves'
disease.
6. A 25-year-old female presents with palpitations, weight loss, and heat
intolerance. Physical examination reveals a diffusely enlarged thyroid with a
bruit. What is the most likely diagnosis?
A. Hashimoto's thyroiditis
B. Subacute thyroiditis
C. Graves' disease
D. Toxic multinodular goiter
, Answer: C. Graves' disease
Rationale: Graves' disease is the most common cause of thyrotoxicosis, an
autoimmune disorder affecting the thyroid gland. It is more common in women
aged 20-40. Clinical findings include a diffusely enlarged thyroid, often
asymmetric with a bruit. Subacute thyroiditis presents with a moderately enlarged,
tender thyroid. Toxic multinodular goiter presents with palpable nodules.
7. Which of the following findings is characteristic of subacute thyroiditis?
A. Diffusely enlarged thyroid with bruit
B. Small nontender goiter
C. Moderately enlarged, tender thyroid with dysphagia and jaw/ear pain
D. Palpable nodules with increased uptake
Answer: C. Moderately enlarged, tender thyroid with dysphagia and jaw/ear
pain
Rationale: Subacute thyroiditis presents with a moderately enlarged, tender thyroid
gland. Patients often experience dysphagia, and jaw/ear pain may be present.
Graves' disease presents with a diffusely enlarged thyroid with bruit. Silent
thyroiditis presents with a small nontender goiter. Toxic multinodular goiter
presents with palpable nodules.
8. A patient's laboratory results show suppressed TSH with elevated T4. In
which of the following conditions would this finding NOT be expected?
A. Graves' disease
B. Toxic multinodular goiter
C. TSH-secreting pituitary tumor
D. Subacute thyroiditis
Answer: C. TSH-secreting pituitary tumor
Rationale: In TSH-secreting pituitary tumors or pituitary hyperplasia (rare), TSH
is elevated rather than suppressed. Most causes of hyperthyroidism, including
Graves' disease, toxic multinodular goiter, and subacute thyroiditis, present with
