When a preserved blood specimen is allowed to stand for a time,
the components will settle into which three distinct layers:
a.Buffy coat (top layer), plasma (grayish white cellular layer
composed of white blood cells and platelets), and red blood cells
(bottom layer).
b.Plasma (top layer), buffy coat (grayish white cellular layer
composed of white blood cells and platelets), and red blood cells
(bottom layer).
c.Plasma (top layer), red blood cells (grayish white cellular layer
composed of white blood cells and platelets), and buffy coat
(bottom layer).
d.Red blood cells (top layer), buffy coat (grayish white cellular
layer composed of white blood cells and platelets), and plasma
(bottom layer). - ✔✔✔ Correct Answer > Correct Answer: Plasma (top
layer), buffy coat (grayish white cellular layer composed of white

What is the process in which a cell engulfs and digests foreign
material?
a.Cellular respiration
b.Homeostasis
c.Osmosis
d.Phagocytosis - ✔✔✔ Correct Answer > Correct Answer: Phagocytosis
Worn out RBCs are broken down by the mononuclear phagocytic
system. These cells are located in the blood sinusoids (tiny blood
vessels) in the liver, spleen, and bone marrow and in the lining of
the lymph channels in the lymph nodes.
Where is the primary site of megakaryocyte development?
a.Blood
b.Bone marrow
c.Liver
,Page 3 of 125
d.Spleen - ✔✔✔ Correct Answer > Correct Answer: Bone marrow
The bone marrow is the major site for megakaryocyte
development.
When evaluating an erythrocyte histogram, a shift to the left of
the erythrocyte series should correspond to which type of
erythrocytes?
a.Macrocytes
b.Microcytes
c.Normocytes
d.Reticulocytes - ✔✔✔ Correct Answer > Correct Answer: Microcytes
A shift to the left of erythrocyte population corresponds to
microcytes.
In most infections, there is some increase in the ESR. What are
two exceptions?
a.Chorea and undulant fever
b.Dyspnea and spasticity
c.Syncope and diaphoresis
, Page 4 of 125
d.Vertigo and myocardial infarction - ✔✔✔ Correct Answer > Correct
Answer: Chorea and undulant fever
ESR is a measure of the presence and severity of pathological
processes. In most infections, there is at least some increase in
the ESR; chorea and undulant fever are two exceptions.
While collecting a sample of blood for hematology testing, what
is the possible outcome of laboratory results if the tube was NOT
inverted during collection?
a.Clot
b.Cross-contamination
c.Falsely increased cell counts
d.No effect - ✔✔✔ Correct Answer > Correct Answer: Clot
If a tube is NOT inverted while collected during a blood draw, the
blood can very likely clot. This is a common pre-analytical error.
Which type of anemia is a group of inherited disorders of Hb
synthesis, characterized by microcytosis, hypochromasia, and
basophilic stippling?
a.Hemolytic anemia
