MULTIPLE CHOICE

1. What is the process by which certain cells engulf and digest microorganisms and cellular
debris?

2. The nurse explains that because it is a reliable and predictable indicator of the body’s level of
infection or recovery the _____________________ is a common diagnostic tool.
a. Hemoglobin
b. Hematocrit
c. Mean cell volume (MCV)
d. Differential
ANS: D
A differential white blood cell count is an examination in which the different kinds of WBCs
are counted and reported as percentages of the total examined. It is a common diagnostic tool
because of its reliability and the predictability of the body’s response to infection or its
progress in recovery.

3. The nurse assessing a differential sees an increase in immature neutrophils (bands) and is
aware that this indicates:
a. a significant hemorrhage.
b. aplastic anemia.
c. an overwhelming bacterial infection.
d. beginning recovery from an infection.
ANS: C
An increase in immature neutrophils (bands) is called bandemia, and it indicates an
overwhelming bacterial infection.

, 4. B cells and T cells fit under which classification?
a. Erythrocytes
b. Basophils
c. Lymphocytes
d. Monocytes

5. The nurse explains that in the event of an invasion of an allergen, the basophils release a
strong vasodilator, which is:

b. prothrombin.
c. hematocrit.
d. histamine.
ANS: D
Histamine is released by the basophils during the invasion of an allergen.

6. The presence of excess bands in the peripheral blood that indicate severe infection is called:
a. shift to the left.
b. shift to the right.
c. bone marrow aspiration.
d. thrombocytosis.
ANS: A
The presence of excess bands in the peripheral blood is called a shift to the left (i.e., a shift
toward immature cells) and indicates severe infection.

7. A patient who had a Schilling test shows a 20% excretion of the radioactive vitamin B12. What
would this indicate?
a.The patient has a low reserve of iron and has iron deficiency anemia.
b.The patient has a normal finding and does not have pernicious anemia.
c.The patient has a deficiency of thrombocytes and has a clotting disorder.
d.The patient has an excess of RBCs and has polycythemia.
ANS: B
