Past medical history is significant for aortic valve replacement surgery 2 years ago. His vital signs include: temperature 36.7C 98.0F, blood pressure 13085 mm Hg, pulse 87min. Physical examination reveals generalized pallor. Skin appears jaundiced. Laboratory findings are significant for the following:Hemoglobin 9.7 gdLReticulocyte count 8Indirect bilirubin 4 mgdLLactate dehydrogenase 250 ULDirect antiglobulin test NegativeWhich of the following would most likely be found on a peripheral blood smear in this patient?? A: Schistocytes, B: Spherocytes, C: Ringed sideroblasts, D: Elliptocytes, E: Target cells,  <response>: This is a patient with progressive fatigue, shortness of breath, brownish urine, and laboratory findings of anemia, increased reticulocytes, increased indirect bilirubin, and increased LDH. This presentation is most consistent with hemolytic anemia. The key finding on peripheral smear in hemolytic anemia would be schistocytes, which are fragmented red blood cells. Spherocytes can be seen in hereditary spherocytosis, a type of hemolytic anemia, but are not typically seen in acquired hemolytic anemias. Ringed sideroblasts indicate a problem with heme synthesis and are seen in sideroblastic anemias. Elliptocytes can be seen in hereditary elliptocytosis but would not explain the hemolytic picture. Target cells can be seen in liver disease, hemoglobinopathies, and after splenectomy, but do not indicate hemolysis.Therefore, schistocytes would be the most likely peripheral smear finding in this patient with hemolytic anemia.A: Schistocytes
