of distribution in the blood of which of the
following types of cells?
1.
Lymphocytes
2.
Monocytes
3.
Leukocytes
4.
Erythrocytes
6-32.
What is the function of leukocytes?
1.
To carry oxygen through the blood
2.
To control various disease conditions
3.
To aid in clotting the blood
4.
Each of the above
6-33.
What type of leukocyte comprises the
largest percentage of cells in the circulating
blood?
1.
Lymphocyte
2.
Neutrophil
3.
Erythocyte
4.
Thrombocyte
6-34.
When viewing a smear for a differential
count, you identify the cells with the large,
scattered dark blue granules that are darker
than their nuclei as
1.
lymphocytes
2.
monocytes
3.
basophils
4.
neutrophils
6-35.
The largest of the normal WBCs is the
1.
monocyte
2.
lymphocyte
3.
eosinophil
4.
basophil
6-36.
On a properly prepared slide for a
differential count, the smear will
1.
extend from one side of the slide to the
other
2.
be evenly distributed on the entire
slide
3.
show no wavy or blank spots
4.
show smooth even edges
6-37.
Properly prepared differential slides require
a longer rinse time than stain time.
1.
True
2.
False
6-38.
If a smear used in a differential count is to
be saved for reexamination, remove the
immersion oil by placing a piece of lens
tissue over the slide and moistening the
tissue with
1.
alcohol
2.
water
3.
xylene
4.
acetone
6-39.
A continued shift to the left with a falling
total WBC count probably indicates
1.
progress toward normal recovery
2.
a decrease in immature neutrophils
3.
a breakdown of the body’s defense
mechanism and is a poor prognosis
4.
a decrease in parasitic and allergenic
conditions
