QUESTION 1
Which laboratory profile is most characteristic of Hashimoto thyroiditis
(primary hypothyroidism)?
A. Low TSH, High Free T4
B. High TSH, Low Free T4
C. High TSH, High Free T4
D. Low TSH, Low Free T4
Correct Answer: B. High TSH, Low Free T4
Rationale: In primary hypothyroidism, the thyroid gland fails to produce
adequate hormones, which triggers the pituitary gland to increase
thyroid-stimulating hormone (TSH) production via negative feedback.
QUESTION 2
Which direction does the characteristic murmur of aortic stenosis
typically radiate?
A. Left axilla
B. Carotid arteries
C. Left sternal border
,D. Epigastric region
Correct Answer: B. Carotid arteries
Rationale: Aortic stenosis produces a crescendo-decrescendo systolic
ejection murmur that is best heard at the second right intercostal space
and radiates characteristically to the neck and carotids.
QUESTION 3
Which adverse effect is most commonly associated with angiotensin-
converting enzyme (ACE) inhibitors?
A. Persistent dry cough
B. Peripheral edema
C. Hypokalemia
D. Tachycardia
Correct Answer: A. Persistent dry cough
Rationale: ACE inhibitors prevent the breakdown of bradykinin, leading
to its accumulation in the respiratory tract, which frequently causes a
chronic, hacking dry cough.
QUESTION 4
Which physical assessment finding is expected over an area of lung
consolidation caused by lobar pneumonia?
A. Hyperresonance to percussion
B. Decreased tactile fremitus
,C. Dullness to percussion and increased tactile fremitus
D. Vesicular breath sounds with prolonged expiration
Correct Answer: C. Dullness to percussion and increased tactile fremitus
Rationale: Consolidated lung tissue replaces air with exudate, creating a
dull percussion note, enhanced vocal resonance, and increased
transmission of tactile fremitus.
QUESTION 5
Which clinical feature distinguishes Crohn disease from ulcerative
colitis?
A. Continuous mucosal inflammation limited to the rectum and colon
B. Skip lesions and transmural inflammation involving any part of the GI
tract
C. Absence of granulomas on histological tissue biopsy
D. Predominant clinical presentation of gross hematuria and mucus
Correct Answer: B. Skip lesions and transmural inflammation involving
any part of the GI tract
Rationale: Crohn disease is characterized by patchy transmural
inflammation (skip lesions) that can affect any segment of the
gastrointestinal tract from mouth to anus.
QUESTION 6
Which joint involvement pattern is most typical of rheumatoid arthritis?
, A. Asymmetric involvement of weight-bearing joints
B. Symmetric polyarthritis of the small joints of the hands and wrists
C. Isolated involvement of the distal interphalangeal joints
D. Acute monoarticular inflammation of the first metatarsophalangeal
joint
Correct Answer: B. Symmetric polyarthritis of the small joints of the
hands and wrists
Rationale: Rheumatoid arthritis is a systemic autoimmune condition
typically presenting with symmetric, additive inflammation of the
metacarpophalangeal and proximal interphalangeal joints.
QUESTION 7
Which pathological mechanism underlies the motor symptoms of
Parkinson disease?
A. Destruction of upper motor neurons in the cerebral cortex
B. Loss of dopaminergic neurons in the substantia nigra pars compacta
C. Demyelination of peripheral sensory and motor nerves
D. Autoimmune destruction of acetylcholine receptors at the
neuromuscular junction
Correct Answer: B. Loss of dopaminergic neurons in the substantia nigra
pars compacta
