Q1 Question 1 of 400
A 62-year-old male presents with crushing chest pain radiating to his left arm. Troponin
levels are elevated and ST-segment elevation is noted on ECG. Which pathophysiologic
mechanism best explains the cellular injury in this patient?
A. Calcium overload leading to mitochondrial dysfunction
B. Potassium depletion causing membrane instability
C. Sodium excess triggering cellular edema
D. Magnesium deficiency impairing ATP synthesis
Correct Answer: A
Rationale:
In myocardial infarction, ischemia causes ATP depletion, leading to failure of the Na+/K+ pump. This results in intracellular
calcium overload via the Na+/Ca2+ exchanger, activating proteases and phospholipases that damage cellular structures and
cause mitochondrial dysfunction.

Q2 Question 2 of 400
A 45-year-old woman with type 2 diabetes presents with numbness and tingling in her feet.
Physical exam reveals loss of vibratory sense and absent ankle reflexes. Which
pathophysiologic process is most responsible for these findings?
A. Non-enzymatic glycation of proteins causing microvascular damage
B. Autoimmune destruction of Schwann cells
C. Vitamin B12 deficiency affecting myelin synthesis
D. Hypoxia-induced axonal degeneration
Correct Answer: A
Rationale:
Diabetic peripheral neuropathy results from chronic hyperglycemia causing non-enzymatic glycation of proteins and lipids,
leading to advanced glycation end-products (AGEs). These AGEs damage microvessels and nerves through oxidative stress
and inflammation.

Q3 Question 3 of 400
A 58-year-old male with a 30-pack-year smoking history presents with hemoptysis and a
persistent cough. CT reveals a spiculated mass in the right upper lobe. Which molecular
pathway is most commonly dysregulated in this type of malignancy?
A. Epidermal growth factor receptor (EGFR) signaling
B. BRCA1/2 tumor suppression
C. Philadelphia chromosome translocation
D. B-cell receptor signaling
Correct Answer: A
Rationale:
Non-small cell lung cancer, particularly adenocarcinoma in smokers, frequently involves EGFR mutations or overexpression,
driving uncontrolled cellular proliferation. BRCA mutations are associated with breast/ovarian cancers.
