The earliest recognizable erythroid precursor on a Wright-stained smear of the bone marrow is: | A. pronormoblast |
This renal hormone stimulates erythropoiesis in the bone marrow: | B. erythropoietin |
Haptoglobin can become depleted in: | B. intravascular hemolysis |
The erythrocyte life span is most directly determined by: | C. membrane deformability |
Normal sequence of erythroid maturation | pronormoblast, basophilic normoblast, polychromatic normoblast, orthochromic normoblast, reticulocyte |
The primary effector of increased erythrocyte production, or erythropoeisis, is: | C. tissue hypoxia |
An increase in the reticulocyte count should be accompanied by: | D. polychromasia (a condition in which the erythrocytes, on staining, show various shades of blue combined with tinges of pink)on the Wright’s stained blood smear |
What property of the normal erythrocyte membrane allows the 7um cell to squeeze through 3um fenestrations in the spleen? | D. deformability |
An increase of erythrocyte membrane rigidity would be predicted to have what effect? | C. decrease in cell life span |
A patient with an anemia due to increased intravascular hemolysis would likely present with what lab results? | B. hemoglobinuria |
