1. A 58-year-old patient presents with sudden onset of severe, tearing chest pain radiating to the
interscapular region. Physical examination reveals a blood pressure discrepancy of 25 mmHg
between the right and left arms and a new diastolic murmur. Which of the following is the most
appropriate initial diagnostic action?
A. Perform a bedside 12-lead ECG to rule out ST-elevation myocardial infarction.
B. Order an immediate portable chest X-ray to assess for mediastinal widening.
C. Initiate an urgent CT angiogram of the chest to evaluate for aortic dissection.
D. Administer sublingual nitroglycerin to manage potential hypertensive crisis.
Answer: C
Rationale: The clinical presentation is classic for aortic dissection, requiring immediate
visualization via CT angiography to confirm the diagnosis. A, B, and D are incorrect because
, they delay definitive diagnosis; nitroglycerin may exacerbate the condition by increasing shear
stress, and ECG/X-ray are insufficient for definitive diagnosis.
CORRECT ANSWER : C
2. An elderly patient with a history of heart failure presents with increasing dyspnea and bilateral
pitting edema. Auscultation reveals an S3 gallop and fine bibasilar crackles. Which diagnostic
finding would best support the diagnosis of acute decompensated heart failure?
A. Elevated B-type natriuretic peptide (BNP) levels.
B. Increased serum creatinine indicating acute kidney injury.
C. Flattened T-waves on a 12-lead ECG.
D. Decreased forced vital capacity on spirometry.
Answer: A
Rationale: BNP is a highly sensitive biomarker for ventricular stretch and volume overload
associated with heart failure. B, C, and D are incorrect because while they may be seen in the
context of systemic illness, they are not specific markers for the diagnosis of heart failure
exacerbation.
CORRECT ANSWER : A
3. During the cranial nerve examination of a patient with suspected stroke, you note ipsilateral loss
of facial sensation and contralateral loss of pain and temperature sensation in the body. This
pattern of sensory deficit indicates a lesion in the:
A. Cerebral cortex.
B. Brainstem (specifically the lateral medulla).
C. Thalamus.
D. Spinal cord (posterior columns).
Answer: B
Rationale: This pattern is indicative of a lateral medullary syndrome (Wallenberg syndrome),
which affects the spinal trigeminal nucleus (ipsilateral face) and the spinothalamic tract
(contralateral body). Options A, C, and D are incorrect as they would produce different
distributions of sensory loss typically involving the entire half of the body or localized cord
symptoms.
, CORRECT ANSWER : B
4. A patient presents with chronic fatigue, unexplained weight loss, and hyperpigmentation of the
palmar creases. Laboratory results show hyponatremia and hyperkalemia. Which diagnostic test
is the gold standard to confirm the suspected underlying pathology?
A. Serum cortisol level.
B. ACTH stimulation test.
C. 24-hour urinary catecholamines.
D. Thyroid-stimulating hormone (TSH) assay.
Answer: B
Rationale: The presentation is suggestive of Addison’s disease (primary adrenal insufficiency);
the ACTH stimulation test confirms the inability of the adrenal glands to produce cortisol. A, C,
and D are incorrect because a random cortisol level is not diagnostic, and the other tests
investigate unrelated endocrine pathologies.
CORRECT ANSWER : B
5. You are evaluating a patient with sudden onset of intense, localized abdominal pain in the right
lower quadrant, accompanied by rebound tenderness and psoas sign positivity. Which of the
following is the most definitive imaging modality for diagnosing appendicitis in this clinical
scenario?
A. Plain abdominal radiography.
B. Computed tomography (CT) of the abdomen and pelvis with contrast.
C. Magnetic resonance imaging (MRI) without contrast.
D. Transabdominal ultrasound.
Answer: B
Rationale: CT with contrast has the highest sensitivity and specificity for confirming appendicitis
and ruling out other surgical emergencies. Options A, C, and D are less effective; ultrasound is
operator-dependent, and plain films lack sufficient diagnostic utility.
CORRECT ANSWER : B
6. In a patient with suspected temporal arteritis, what is the most critical next step to prevent
irreversible vision loss?
, A. Referral for an immediate temporal artery biopsy.
B. Initiation of high-dose systemic corticosteroid therapy.
C. Measurement of erythrocyte sedimentation rate (ESR).
D. Ophthalmoscopic examination to identify optic disc edema.
Answer: B
Rationale: Temporal arteritis (Giant Cell Arteritis) is a medical emergency where immediate
corticosteroids are required to prevent permanent blindness, even before biopsy confirmation.
Options A, C, and D are incorrect because they prioritize diagnostics over the urgent therapeutic
intervention needed to save vision.
CORRECT ANSWER : B
7. A 45-year-old female presents with episodic palpitations, diaphoresis, and severe headaches. Her
blood pressure is 190/110 mmHg. Which biochemical workup is most appropriate?
A. Serum TSH and T4 levels.
B. Plasma fractionated metanephrines.
C. Serum aldosterone-to-renin ratio.
D. Serum calcium and parathyroid hormone levels.
Answer: B
Rationale: The clinical triad (headache, sweating, tachycardia) and hypertension are highly
suggestive of pheochromocytoma, which is best screened for via plasma or urine metanephrines.
A, C, and D are incorrect because they investigate other causes of hypertension/palpitations that
do not match the specific clinical triad.
CORRECT ANSWER : B
8. A patient presents with acute monoarticular arthritis of the first metatarsophalangeal joint.
Arthrocentesis reveals negatively birefringent, needle-shaped crystals. What is the diagnosis?
A. Rheumatoid arthritis.
B. Pseudogout (calcium pyrophosphate deposition).
C. Gout (monosodium urate crystals).
