Exam 8: Introduction to Anemia

A blood sample has moderate spherocytes, schistocytes, and polychromasia on the smear.What would you expect the results of the following to be? A)Bilirubin B)LDH C)Hemoglobin D)Retic count E)M:E ratio

An instrument printout reveals an RDW of 33.Which of the following would best correlate with those results?

An increased red cell distribution width (RDW) usually indicates what abnormality?

A peripheral blood smear has an even distribution of both normocytic normochromic cells and microcytic hypochromic cells.What is this phenomenon called?

A patient has hemolytic anemia.An instrument printout reveals a reticulocyte count of 8%, marked polychromasia and moderate schistocytes, and an MCV of 88 fl.What can be concluded about the bone marrow response to this hemolytic anemia?

Codocytes are associated with all of the following conditions except:

What staining method can be used to differentiate Pappenheimer bodies from reticulocytes?

A patient presents with a RPI of greater than 2 and macrocytic morphology of the red blood cells.Which survival defect does this most likely represent?

How would you differentiate between an acanthocyte and an echinocyte?

What RBC inclusions cannot be seen with Romanowsky stain but can be visualized with supravital stain?

Acanthocytes or spur cells have membranes with irregular distribution of spikes.What other significant feature does this cell possess?

A patient sample had a retic count of 5%.The patient's hematocrit was 25%.Normal hematocrit is 45%.What other bone marrow test(s) could you perform to help determine if the bone marrow is responding to the pancytopenia?

A patient with a bleeding problem is complaining to her physician about excessive fatigue.Physical examination reveals a thin, pale woman with pale mucosal membranes.Significant CBC findings include an MCV of 70 fl.Based on these findings follow-up testing should be ordered for:

An instrument printout has an RPI of 1.3, a hemoglobin of 7 g/dL and an MCV of 112 fl.What can be concluded from this?

CBC results on a pregnant patient indicate an MCV of 112 fl.What would be the most appropriate reflex test?
