Answer to Question 1

ANS: C
The earliest cell that can be identified by morphology, using Wright stain, as belonging to the granulocyte maturation sequence is the myeloblast. The pluripotent stem cell and the CFU-GEMM are identified by various receptors present on the cell membrane using monoclonal antibodies and flow cytometric techniques. The myelocyte is a later stage of development than the myeloblast.

Answer to Question 2

ANS: B
The clinician performs the white blood cell (WBC) count by counting the number of white cells in blood. However, a pool of granulocytes exists that is marginated (clinging to the sides of small blood vessels). Even though they are still in the blood vessel, these granulocytes are not freely circulating and are not counted. Only freely circulating white cells of all types are counted.
