Q1 Question 1 of 186
A 68-year-old male with a history of hypertension presents with sudden onset of tearing chest
pain that radiates to his back. His blood pressure is 190/110 mmHg in the right arm and 140/90
mmHg in the left arm. What is the most likely diagnosis?
Acute myocardial infarction
Aortic dissection
Pulmonary embolism
Pericarditis
Correct Answer: B
Rationale:
Aortic dissection classically presents with tearing chest pain radiating to the back and unequal blood pressures between
arms (pulse deficit). The hypertension and acute onset are risk factors. MI typically presents with pressure-like pain, PE with
pleuritic pain and dyspnea, and pericarditis with positional pain.
Q2 Question 2 of 186
A 55-year-old male with a 40 pack-year smoking history presents with a 3-month history of cough,
hemoptysis, and unintentional weight loss of 15 pounds. Chest X-ray reveals a 4 cm mass in the
right upper lobe. Which type of lung cancer is most likely given this presentation?
Small cell lung cancer
Adenocarcinoma
Squamous cell carcinoma
Large cell carcinoma
Correct Answer: C
Rationale:
Squamous cell carcinoma is strongly associated with smoking, typically presents centrally in the upper lobes, and is the
most common type to cause hemoptysis and cavitation. Adenocarcinoma is more common in non-smokers and presents
peripherally, while small cell cancer causes more paraneoplastic syndromes.

, Q3 Question 3 of 186
A 42-year-old female presents with progressive dyspnea on exertion, orthopnea, and paroxysmal
nocturnal dyspnea. On examination, she has elevated jugular venous pressure, bilateral basilar
crackles, and an S3 gallop. Which pathophysiologic mechanism best explains these findings?
Left ventricular systolic dysfunction leading to pulmonary congestion
Right ventricular failure leading to systemic venous congestion
Mitral stenosis leading to left atrial enlargement
Pulmonary hypertension leading to right heart strain
Correct Answer: A
Rationale:
Dyspnea on exertion, orthopnea, PND, JVD, basilar crackles, and S3 gallop are classic signs of left-sided heart failure with
pulmonary congestion due to left ventricular systolic dysfunction. Right-sided failure would show peripheral edema and
hepatomegaly without pulmonary symptoms.
Q4 Question 4 of 186
A 35-year-old male presents with severe epigastric pain that radiates to his back, nausea, and
vomiting. His serum lipase is 1,200 U/L (normal <160). He admits to heavy alcohol consumption
over the past week. What is the most likely complication that would develop within the first 48
hours?
Pseudocyst formation
Acute respiratory distress syndrome (ARDS)
Chronic pancreatic insufficiency
Pancreatic adenocarcinoma
Correct Answer: B
Rationale:
Severe acute pancreatitis can lead to ARDS within 48 hours due to systemic inflammatory response and capillary leak.
Pseudocysts take 4-6 weeks to form, chronic insufficiency develops over years, and adenocarcinoma is unrelated to acute
alcoholic pancreatitis.

, Q5 Question 5 of 186
A 60-year-old male with a history of atrial fibrillation presents with sudden onset of left-sided
weakness and aphasia. CT scan of the brain shows no hemorrhage. Which mechanism is most
likely responsible for this patient's stroke?
Thrombotic occlusion of a small penetrating artery
Embolization from the left atrial appendage
Lacunar infarction due to lipohyalinosis
Subarachnoid hemorrhage from an aneurysm
Correct Answer: B
Rationale:
In atrial fibrillation, blood stasis in the left atrial appendage promotes thrombus formation, which can embolize to the cerebral
circulation causing ischemic stroke. The absence of hemorrhage on CT and the sudden onset with AF history strongly
support a cardioembolic mechanism.
Q6 Question 6 of 186
A 45-year-old female presents with fatigue, dyspnea, and palpitations. Laboratory studies reveal
hemoglobin of 7.2 g/dL, MCV of 68 fL, and ferritin of 12 ng/mL. Which finding on peripheral blood
smear would be most consistent with this diagnosis?
Macrocytic red blood cells with hypersegmented neutrophils
Microcytic, hypochromic red blood cells with pencil cells
Normocytic red blood cells with schistocytes
Spherocytes with increased reticulocyte count
Correct Answer: B
Rationale:
Microcytic hypochromic RBCs with pencil cells (elliptocytes) are characteristic of iron deficiency anemia, consistent with low
MCV and low ferritin. Macrocytic cells suggest B12/folate deficiency, schistocytes suggest microangiopathic hemolysis, and
spherocytes suggest hereditary spherocytosis or autoimmune hemolysis.
