Question 1: A 72-year-old male with a history of hypertension and type 2 diabetes
presents with sudden onset of severe, tearing chest pain radiating to his back. His
blood pressure is 180/110 mmHg in his right arm and 140/80 mmHg in his left arm.
Which of the following is the most appropriate initial imaging modality to confirm
the suspected diagnosis?
A. Computed tomography angiography (CTA) of the chest
B. Transthoracic echocardiogram (TTE)
C. Magnetic resonance imaging (MRI) of the chest
D. Standard chest radiograph
CORRECT ANSWER: A. Computed tomography angiography (CTA) of the chest
Rationale:The patient's presentation is classic for an acute aortic dissection. CTA of the
chest is the gold-standard initial imaging modality due to its high sensitivity and
specificity, rapid acquisition, and widespread availability. It provides excellent
visualization of the intimal flap and the extent of the dissection. TTE can be useful but is
less sensitive than CTA. MRI is also highly accurate but is not typically the first-line due
to longer acquisition time and limited availability in emergencies. A chest X-ray may
show a widened mediastinum, but it is neither sensitive nor specific enough to confirm
the diagnosis.
Question 2: A 45-year-old female with a history of systemic lupus erythematosus
(SLE) presents with progressive dyspnea on exertion and a non-productive cough. A
chest CT shows diffuse ground-glass opacities with a "crazy-paving" pattern.
Which of the following is the most likely pulmonary manifestation of her underlying
disease?
A. Pulmonary embolism
B. Diffuse alveolar hemorrhage
C. Acute lupus pneumonitis
D. Bronchiolitis obliterans
CORRECT ANSWER: C. Acute lupus pneumonitis
Rationale:Acute lupus pneumonitis is a rare but severe manifestation of SLE,
presenting with dyspnea, cough, and hypoxia. Imaging typically reveals diffuse bilateral
infiltrates or ground-glass opacities, which can progress to consolidation. The "crazy-
paving" pattern, while not exclusive to lupus pneumonitis, is a common finding in this
condition. Diffuse alveolar hemorrhage is another pulmonary manifestation of SLE, but
,it is more commonly associated with hemoptysis and a drop in hemoglobin. Pulmonary
embolism and bronchiolitis obliterans are less directly associated with the described
imaging findings in an SLE patient.
Question 3: A 60-year-old male with a 30-pack-year smoking history presents with
hemoptysis and weight loss. A chest CT reveals a 3-cm solid mass in the right
upper lobe with speculation. Which of the following is the most appropriate next
step in the management of this patient?
A. Positron emission tomography-computed tomography (PET-CT)
B. Bronchoscopy with biopsy
C. Empirical broad-spectrum antibiotics
D. Surgical resection
CORRECT ANSWER: B. Bronchoscopy with biopsy
Rationale:The patient has a highly suspicious lung lesion in the right upper lobe, which
is accessible via bronchoscopy. A tissue diagnosis is essential to confirm malignancy
and to determine the histologic subtype, which guides further management. PET-CT is
useful for staging but should not precede tissue confirmation. Empirical antibiotics are
indicated if an infection is suspected, but the presentation is more concerning for
malignancy. Surgical resection is not appropriate without a confirmed diagnosis.
Question 4: A 55-year-old female presents with a 6-month history of progressive
muscle weakness, dry cough, and Raynaud's phenomenon. Her physical exam
reveals heliotrope rash and Gottron's papules. Which of the following laboratory
findings is most specific for her condition?
A. Anti-Jo-1 antibodies
B. Anti-Scl-70 antibodies
C. Anti-centromere antibodies
D. Anti-dsDNA antibodies
CORRECT ANSWER: A. Anti-Jo-1 antibodies
Rationale:The patient's presentation is classic for dermatomyositis, characterized by
proximal muscle weakness, heliotrope rash, and Gottron's papules. Anti-Jo-1 antibodies
are a myositis-specific antibody strongly associated with the anti-synthetase syndrome,
which is a subset of dermatomyositis/polymyositis that also includes interstitial lung
disease and Raynaud's phenomenon. Anti-Scl-70 and anti-centromere are associated
with systemic sclerosis, and anti-dsDNA is specific for SLE.
Question 5: A 28-year-old male with no significant medical history presents with
acute onset of severe right-sided flank pain radiating to his groin, accompanied by
,nausea and hematuria. His urinalysis shows numerous red blood cells. Which of
the following is the most likely diagnosis?
A. Acute pyelonephritis
B. Renal cell carcinoma
C. Nephrolithiasis
D. Urinary tract infection
CORRECT ANSWER: C. Nephrolithiasis
Rationale:The classic presentation of acute renal colic is sudden, severe flank pain
radiating to the groin, often associated with nausea, vomiting, and hematuria. The
presence of hematuria on urinalysis supports this diagnosis. Acute pyelonephritis
typically presents with fever, chills, and costovertebral angle tenderness. Renal cell
carcinoma may cause hematuria but is usually asymptomatic and presents as an
incidental finding on imaging. A urinary tract infection would typically present with
dysuria and frequency.
Question 6: A 70-year-old male with a history of coronary artery disease and heart
failure presents with increasing shortness of breath and lower extremity edema.
His medications include lisinopril, metoprolol, and furosemide. Which of the
following is the most likely cause of his worsening symptoms?
A. Acute myocardial infarction
B. Medication non-adherence
C. Progressive renal failure
D. Worsening of underlying heart failure
CORRECT ANSWER: D. Worsening of underlying heart failure
Rationale:The patient's symptoms of increasing dyspnea and edema are classic signs
of worsening heart failure, which is a common progression in patients with underlying
coronary artery disease. While acute myocardial infarction could cause a
decompensation, the gradual worsening of symptoms is more consistent with a chronic
exacerbation. Medication non-adherence and renal failure are possible causes, but the
most direct and common reason is the natural progression of the disease.
Question 7: A 35-year-old female presents with fatigue, weight gain, cold
intolerance, and constipation. Her physical exam reveals a bradycardia and a non-
pitting edema around her eyes. Which of the following laboratory findings would
confirm the diagnosis?
A. Elevated T3 and T4
B. Elevated TSH and low T4
, C. Low TSH and elevated T4
D. Elevated TSH and elevated T4
CORRECT ANSWER: B. Elevated TSH and low T4
Rationale:The patient's symptoms are classic for primary hypothyroidism. In primary
hypothyroidism, the thyroid gland is unable to produce sufficient thyroid hormones (T3
and T4), leading to a compensatory increase in TSH from the pituitary gland. Therefore,
an elevated TSH with a low free T4 confirms the diagnosis.
Question 8: A 50-year-old male with a history of alcohol use disorder presents with
confusion, ataxia, and ophthalmoplegia. Which of the following vitamin
deficiencies is the most likely cause?
A. Vitamin B12
B. Vitamin B1 (Thiamine)
C. Vitamin B3 (Niacin)
D. Vitamin B6 (Pyridoxine)
CORRECT ANSWER: B. Vitamin B1 (Thiamine)
Rationale:The classic triad of confusion, ataxia, and ophthalmoplegia is Wernicke's
encephalopathy, which is caused by a deficiency of thiamine (vitamin B1). This
condition is commonly seen in patients with chronic alcohol use disorder due to poor
nutrition and impaired absorption. While other vitamin deficiencies can cause
neurological symptoms, this specific triad is pathognomonic for Wernicke's
encephalopathy.
Question 9: A 25-year-old female presents with a 3-day history of fever, chills, and
painful urination. Her urinalysis shows leukocyte esterase and nitrites. Which of
the following is the most appropriate initial antibiotic for an uncomplicated urinary
tract infection?
A. Ciprofloxacin
B. Trimethoprim-sulfamethoxazole
C. Nitrofurantoin
D. Amoxicillin
CORRECT ANSWER: C. Nitrofurantoin
Rationale:For an uncomplicated urinary tract infection, the current guidelines
recommend nitrofurantoin as a first-line agent due to its high efficacy and low
resistance rates. It achieves high concentrations in the urine and is well-tolerated.
Trimethoprim-sulfamethoxazole is another option, but resistance can be high in some
communities. Ciprofloxacin is a fluoroquinolone and is reserved for more complicated
