The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 59-year-old man presents to his primary care provider with fatigue. He has been seen in the emergency room 5 times in the past 2 years for acute alcohol intoxication. His past medical history is notable for diabetes mellitus and gout. He takes metformin, glyburide, and allopurinol. His temperature is 98.6°F (37°C), blood pressure is 130/85 mmHg, pulse is 86/min, and respirations are 16/min. He is in no acute distress. A positive fluid wave is noted. The dorsal surface of the tongue is depapillated, and there are erythematous swollen patches at the oral commissures. A complete blood count and iron studies are reported below:  Hemoglobin: 12.1 g/dL Hematocrit: 36% Leukocyte count: 6,000/mm^3 with normal differential Platelet count: 170,000/mm^3  Mean corpuscular volume: 70 um^3 Iron: 250 ug/dL Ferritin: 300 ng/mL Total iron binding capacity: 200 mcg/dL^3  Which of the following findings is most likely to be seen in this patient?   (A) Erythroblasts with mitochondrial iron deposits   (B) Erythrocytes lacking central pallor   (C) Erythrocytes with a ring of relative pallor   (D) Inclusions of denatured hemoglobin
