The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 50-year-old man presents to the office with complaints of fever and chills for 4 weeks. He adds that he is fatigued all the time and has generalized weakness. He has drenching night sweats and has had 2 episodes of non-bilious vomiting over the past few days. He traveled to the Netherlands for 4 days a month ago. His symptoms started a few days after he returned home. Laboratory testing revealed the following: Hemoglobin 11.2 g/dL Hematocrit 29% Leukocyte count 2,950/mm3 Neutrophils  59% Bands  3% Eosinophils 1% Basophils  0% Lymphocytes 31% Monocytes  4% Platelet count  60,000/mm3 Unconjugated bilirubin 12 mg/dL Alanine aminotransferase 200 IU/L Aspartate aminotransferase 355 IU/L The peripheral blood smear showed basophilic ring- and pear-shaped structures inside many red cells and extracellular basophilic rings on Wright-Giemsa staining. Further evaluation revealed parasitemia and a few schistocytes, poikilocytes, and merozoites in tetrad formation. The findings are most consistent with which diagnosis?   (A) Malaria   (B) Babesiosis   (C) Tuberculosis   (D) Lyme disease
