aVF. Which coronary artery is most likely occluded?
A. Left anterior descending artery
B. Left circumflex artery
C. Right coronary artery
D. Posterior descending artery
Answer: C. Right coronary artery
Rationale: Inferior wall myocardial infarctions involving leads II, III, and
aVF are most commonly caused by occlusion of the right coronary artery.
, 2. A 25-year-old woman presents with exophthalmos, weight loss, and
heat intolerance. Laboratory testing reveals suppressed TSH and
elevated free T4. What is the most likely diagnosis?
A. Hashimoto thyroiditis
B. Graves disease
C. Subacute thyroiditis
D. Toxic adenoma
Answer: B. Graves disease
Rationale: Graves disease is characterized by autoimmune stimulation of
TSH receptors, producing hyperthyroidism and ophthalmopathy.
3. A patient with nephrotic syndrome is most at risk for which
complication?
A. Polycythemia
B. Hypercalcemia
C. Thromboembolism
D. Metabolic alkalosis
Answer: C. Thromboembolism

A. Increased transferrin saturation
B. Increased serum iron
C. Increased total iron-binding capacity
D. Increased ferritin
Answer: C. Increased total iron-binding capacity
Rationale: Iron deficiency anemia is associated with low ferritin, low serum
iron, and elevated total iron-binding capacity.
7. Which organism is the most common cause of community-acquired
pneumonia?
A. Staphylococcus aureus
B. Mycoplasma pneumoniae
