CHAPTER 46: CARE OF THE PATIENT WITH
A BLOOD OR LYMPHATIC DISORDER
QUESTIONS AND ANSWERS 2022
1.What is the process by which certain cells engulf and
... [Show More] digest microorganisms and
cellular debris?
a. Erythrocytosis
b. Hematocrit
c. Phagocytosis
d. Hemostasis - ANS: C
Phagocytosis is the process by which bacteria, cellular debris, and solid particles are
destroyed and removed.
29.The nurse is aware that persons of the Jehovahs Witness faith accept which types of
blood transfusions?
a. No type of blood transfusion
b. Blood that has been blessed by their religious leader
c. Transfusions only for persons who have not yet been baptized
d. Autologous blood transfusions - ANS: D
Jehovahs Witness followers are accepting of autologous blood transfusions and some
will accept volume expanders such as colloids.
2.The nurse explains that because it is a reliable and predictable indicator of the bodys
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 bodys 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 - 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
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
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.
8.In an adult, where are erythrocytes continuously produced?
a. Yellow bone marrow
b. Lymphatic system
c. Spleen
d. Red bone marrow - ANS: D
Erythrocytes are continuously produced in the red bone marrow, principally in the
vertebrae, ribs, and sternum.
9.What does the elevation in the eosinophil count to 10% indicate?
a. Anemia
b. Allergy
c. Infection
d. Hypoxia - ANS: B
