input: The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 54-year-old male presents to his primary care physician complaining of fatigue. He reports that he recently went on a vacation to South America with his family but just wanted to stay in his hotel all day due to fatigue. His past medical history is notable for hyperlipidemia and hypertension. He takes lovastatin and lisinopril. He drinks socially and has a 20 pack-year smoking history. His temperature is 99°F (37.2°C), blood pressure is 130/75 mmHg, pulse is 80/min, and respirations are 16/min. On exam, the patient is appropriately interactive and in no acute distress. Mild splenomegaly is noted. Laboratory analysis reveals the following:  Hemoglobin: 11.0 g/dL Hematocrit: 36% Leukocyte count: 3,800/mm^3 with normal differential Platelet count: 140,000/mm^3  A bone marrow aspiration is ordered but after multiple attempts, they are unable to obtain an adequate bone marrow sample. A peripheral blood smear would likely reveal cells that stain with which of the following stains?   (A) Prussian Blue   (B) Ziehl-Neelsen   (C) Periodic acid-Schiff   (D) Tartrate-resistant acid phosphatase
