• Which of the following symptoms is commonly associated with

polycythemia vera (PV)?

• Fever and chills
• Fatigue and weakness
• Red face, hands, feet, ears, headache, drowsiness
• Night sweats

Answer: C

Explanation: Polycythemia vera is characterized by increased red blood

cell mass, leading to symptoms such as ruddy complexion, headaches, dizziness, and drowsiness due to impaired circulation.

• What laboratory findings are indicative of polycythemia vera?
• Decreased erythrocytes and leukocytes
• Increased erythrocytes, leukocytes, and platelets
• Normal blood cell counts
• Decreased hemoglobin levels

Answer: B

Explanation: Patients with polycythemia vera typically exhibit elevated

levels of red blood cells (erythrocytes), white blood cells (leukocytes), and platelets, reflecting the myeloproliferative nature of the condition.

• Which myeloproliferative disorder is characterized by increased blood

volume and viscosity?

• Essential thrombocythemia
• Chronic myeloid leukemia
• Polycythemia vera
• Myelodysplastic syndrome 2 / 4

Answer: C

Explanation: Polycythemia vera is known for increased blood cell

production, resulting in elevated blood volume (hypervolemia) and viscosity, which can lead to complications like thrombosis.

• A 57-year-old male presents with a red face, headache, and excessive

drowsiness. A blood smear shows increased erythrocytes. What condition does this indicate?

• Iron deficiency anemia
• Thrombocytopenia
• Polycythemia vera (PV)
• Aplastic anemia

Answer: C

Explanation: The described symptoms and laboratory findings are

characteristic of polycythemia vera, a myeloproliferative neoplasm resulting in excessive erythrocyte production.

• What symptom is a 67-year-old female patient with polycythemia vera

most likely to report?

• Swelling in the lower extremities
• Chest pain
• Nausea
• Coughing

Answer: B 3 / 4

Explanation: Chest pain is common in patients with polycythemia vera due

to increased blood viscosity, leading to reduced perfusion and potential ischemic events.

• What type of inherited disorder are alpha and beta thalassemias classified

as?

• X-linked dominant
• Autosomal dominant
• Autosomal recessive
• Multifactorial

Answer: C

Explanation: Both alpha and beta thalassemias are inherited in an

autosomal recessive manner, meaning two copies of the mutated gene are required for the disease to manifest.

• The presence of abnormal hemoglobin, specifically Hb S, is characteristic

of which condition?

• Sickle Cell Disease
• Iron Deficiency Anemia
• Thalassemia
• Aplastic Anemia

Answer: A

Explanation: Hemoglobin S is an abnormal variant resulting from a genetic

mutation that leads to sickle-shaped red blood cells, characteristic of sickle cell disease.
