Question 2

In iron deficiency anemia, the reticulocyte count is typically elevated.

  • True
  • False
Question 3

How do oral contraceptive pills increase the risk of deep vein thrombosis?

  • Estrogen decreases protein S levels
  • Progestin increases antithrombin activity
  • Estrogen increases platelet production by the bone marrow
  • Progestin causes endothelial fibrinoid necrosis
Question 4

Fill in the blank

Question 5

Which test is the confirmatory test of choice for hereditary spherocytosis?

  • Eosin-5-maleimide (EMA) binding test
  • Osmotic fragility test
  • Direct Coombs test
  • Hemoglobin electrophoresis
Question 6

A patient on digoxin presents with ventricular fibrillation, hyperkalemia, and altered mental status. What is the appropriate treatment?

  • Digoxin-specific antibody Fab fragments
  • Calcium chloride infusion
  • Higher-dose digoxin to stabilize the rhythm
  • Furosemide to lower serum potassium
Question 7

In patients older than 65 years, bioprosthetic heart valves are generally preferred over mechanical valves because valve degeneration is slower and long-term anticoagulation is not required.

  • True
  • False
Question 8

  • Nasopharyngeal carcinoma
  • Oropharyngeal carcinoma of the tonsil
  • Laryngeal squamous cell carcinoma
  • Esophageal adenocarcinoma
Question 10

How is polycythemia vera initially managed?

  • Therapeutic phlebotomy plus low-dose aspirin

  • Therapeutic phlebotomy plus full-dose warfarin
  • Observation without intervention
Question 11

Which antihypertensive class is first-line for African American patients with hypertension and no other compelling indication?

  • Bernard-Soulier syndrome
  • Glanzmann thrombasthenia
  • Immune thrombocytopenia (ITP)
  • Von Willebrand disease

  • Acute tubular necrosis
  • Acute pyelonephritis
Question 18

Which imaging study is preferred to confirm renal vein thrombosis in a patient with acute kidney injury?

  • Magnetic resonance venography
  • Computed tomography angiography
  • Renal ultrasound
  • Intravenous pyelography

  • Topiramate and valproate
Question 23

A patient who lives in a basement develops erythrocytosis during the winter. What is the most likely mechanism?
