Which of the following is an immature granulocyte with a non-
segmented nucleus?
a.Band neutrophil
b.Basophil
c.Eosinophil
d.Lymphocyte - Correct AnswerCorrect Answer: Band neutrophil
Band neutrophils are immature granulocytes that lack a filament, and
thus have a non-segmented nucleus. They are typically rod or band
shaped.
What is a Hematology stain that is used to make white blood cell
differential smears?
a.Gram stain
b.Hematoxylin and eosin stain
c.Supravital stain
d.Wright stain - Correct AnswerCorrect Answer: Wright stain

, AMT MEDICAL LABORATORY SCIENTIST
Wright stain is used to make white blood cell differential smears in
Hematology. The methodology is the following: a mixture of eosin and
methylene blue are used to observe the cellular morphology of blood
cells in examination of blood films; a polychromatic Romanovsky-type
stain.
What hematological disease/disorder has an increased number of
immature cells?
a.Acute leukemia
b.Anemia
c.Chronic leukemia
d.Lymphoma - Correct AnswerCorrect Answer: Acute leukemia
Increased numbers of immature cells are seen in acute leukemias, with
the predominating cells being myeloblasts and promyelocytes.
What type of cell does the monocyte transition into once it leaves the
blood and enters the tissue?
a.Macrophage
b.Mesothelial cell
c.Monoblast
d.Promonocyte - Correct AnswerCorrect Answer: Macrophage

The monocyte transitions into a macrophage once it leaves the blood
and enters the tissues.
The inclusion of Auer rods in blast cells can help establish diagnosis of
which type of leukemia?
a.Acute lymphocytic leukemia
b.Acute myelocytic leukemia
c.Chronic lymphocytic leukemia
d.Myelodysplastic syndrome - Correct AnswerCorrect Answer: Acute
myelocytic leukemia
Auer rods can help establish the diagnosis of acute myelocytic leukemia
because these inclusions are not found in acute lymphocytic leukemia.
What instrument suspends cells in fluid flow one at a time through a
focused beam of light?
a.Flow cytometer
b.Gas chromatograph
c.HPLC
d.Mass spectrometer - Correct AnswerCorrect Answer: Flow cytometer
A flow cytometer is an instrument in which cells suspended in fluid flow
one at a time through a focused beam of light. The light is scattered in

patterns characteristic of the cells and their components. A sensor
detecting the scattered light measures the volume and other
characteristics of individual cells.
Which cellular constituent of blood contains the vital protein
hemoglobin?
a.Erythrocytes
b.Granulocytes
c.Leukocytes
d.Platelets - Correct AnswerCorrect Answer: Erythrocytes
Erythrocytes are nonnucleated biconcave disk-shaped peripheral blood
cells containing hemoglobin. Its primary function is the transport and
delivery of oxygen to tissues.
Which mononuclear phagocytes are important in the defense against
microorganisms, including mycobacteria, fungi, bacteria, protozoa, and
viruses?
a.Electrolytes and monoblasts
b.Lymphocytes and thrombocytes
c.Monocytes and macrophages
