MULTIPLE CHOICE

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

a. Erythrocytosis b. Hematocrit
c. Phagocytosis d. Hemostasis

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.

  1. Hemoglobin
  2. Hematocrit
  3. Mean cell volume (MCV)
  4. 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:

  1. a significant hemorrhage.
  2. aplastic anemia.
  3. an overwhelming bacterial infection.
  4. 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

ANS: C
B cells and T cells, the major players in the antigen/antibody conflict, are both lymphocytes.

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

c. hematocrit. d. histamine.

ANS: D

6. The presence of excess bands in the peripheral blood that indicate severe infection is called:

  1. shift to the left.
  2. shift to the right.
  3. bone marrow aspiration.
  4. 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?

  1. The patient has a low reserve of iron and has iron deficiency anemia.
  2. The patient has a normal finding and does not have pernicious anemia.
  3. The patient has a deficiency of thrombocytes and has a clotting disorder.
  4. The patient has an excess of RBCs and has polycythemia.

ANS: B
The Schilling test is a laboratory blood test for diagnosing pernicious anemia. The normal reading 24 hours after the administration of radioactive vitamin B12 is 8% to 40%. The test measures the absorption of radioactive vitamin B12.
