The following statements are true about neutrophil development, except:
Neutrophil development occurs in the bone marrow and shares a common
progenitor with monocytes but is distinct from eosinophils and basophils
through GMP
The major cytokine responsible for the stimulation of neutrophil production is the
granulocyte colony-stimulating factor or G-CSF
There are three pools of developing neutrophils in the bone marrow and they are
known as the stem cell, proliferation, and maturation pools
The proliferation pool consists of cells that are undergoing nuclear maturation
that form the marrow reserve and are available for release in the forms of
metamyelocytes, band neutrophils andsegmented neutrophils

the marrow reserve and are available for release in the forms of metamyelocytes, band
neutrophils andsegmented neutrophils
The following statements are true as preanalytical errors in preparing the manual
capillary tube for hematocrit test, except:
Improper sealing of the capillary tube causes a decreased hematocrit readingA
short draw in the EDTA evacuated tube decreases the hematocrit reading as a
result ofRBC shrinkage
A decreased or increased result may occur if the specimen was not mixed
properly
Insufficient centrifugation or a delay in reading results after centrifugation
causeshematocrit readings to decrease
Insufficient centrifugation or a delay in reading results after centrifugation
causeshematocrit readings to decrease
The following statements are true about mature basophils, except:
Their nucleus is usually bilobed with a coarsely clumped chromatin
Their cytoplasm is lavender to colorless with abundant and large primary
granules that appear pink to pale pink and immature stages are very common and
, easily identified
Their granules are water-soluble and may be washed out during staining thus
appearingas empty areas in the cytoplasm.
Their cytoplasm is lavender to colorless with abundant and large primary granules that
appear pink to pale pink and immature stages are very common and easily identified
The common lymphoid progenitor lineage gives rise to the following cells,
except: Plasma cells
Megakaryoblasts
Natural killer cells
Dendritic cells
Megakaryoblasts
The following are accurate descriptions of mature eosinophils, except:
Their nucleus has two to three lobes and is connected by thin filaments but the
majority of cells have two lobes
Their cytoplasm is cream colored and they have abundant secondary granules
showing dark orange color
They are fragile and may easily fracture when preparing blood smears and the
cytoplasm predominates over the nucleus
The reference value in the peripheral blood is 10% to 20%
The reference value in the peripheral blood is 10% to 20%
In a Wright-stained peripheral blood fi lm, the reticulocyte
will have a blue appearance. This is referred to as
megaloblastic maturation
bluemia
Polychromatophilia
Erythroblastosis
Polychromatophilia
Which of the following is (are) characteristic(s) of megaloblastic maturation?
Cells of some leukocytic cell lines are smaller than normal
Nuclear maturation lags behind cytoplasmic maturation
Cytoplasmic maturation lags behind nuclear maturation
Erythrocytes are smaller than normal
Nuclear maturation lags behind cytoplasmic maturation
An adult patient has a reticulocyte count of 4.8% and a Hct of 30%. This results
indicate
adequate bone marrow response
inadequate bone marrow
response
within normal range
cannot be determined
inadequate bone marrow
Which of the following determines the timing of egress of RBCs from the bone
marrow?
Stromal cells decrease production of adhesive molecules over time as RBCs
mature.
Endothelial cells of the venous sinus form pores at specified intervals of time,
