Exam 7: Normochromic Anemias: Biochemical, Membrane, and Miscellaneous Red Blood Cell Disorders

Spherocytes do not function well in the splenic environment because the:

Bite cells are formed from:

-The cells circled below show an eccentric "puddling" of their hemoglobin contents.This is most closely associated with:

Red cells that are rigid, provide resistance to malaria, and spoon shaped are termed:

The deficit of which of these is most closely associated with Southeast Asian ovalocytosis?

Spherocytes differ from normal cells in all of the following ways except:

-The cell at the tip of the pointer is referred to as a:

Which of the following red blood cell membrane defects results in an increased sensitivity to complement lysis?

An anemia that manifests as decreased marrow cellularity, pancytopenia, and a reticulocytopenia is appropriately termed:

In hereditary spherocytosis, the reticulocyte count will typically be:

Individuals with Fanconi's anemia characteristically will have:

Spherocytes may enter the circulation via a variety of mechanisms.To distinguish the CBC of a patient with hereditary spherocytosis from the CBC of a patient with autoimmune hemolytic anemia, one could use the:

Which of the following is most closely associated with G6PD deficiency?

-The cell pictured at the tip of the pointer is known as a (an):

The inability of the red blood cell to generate ATP for membrane function is most closely associated with:

One of the least severe clinical manifestations of G6PD deficiency is:

-The inclusions pictured below are seen with supravital staining only.These inclusions are most likely:

Cholelithiasis is a frequent complication of patients with hereditary spherocytosis because:

The RBC inclusions that are composed of denatured hemoglobin are called:

An osmotic fragility test is performed on a patient's sample.Initial hemolysis occurs at 0.75% NaCl and complete hemolysis occurs at 0.50% NaCl.These results are indicative of which of the following disorders?
