Question 1

Which vessel normally demonstrates the most rapid blood flow?
Selected Answer: c. The vena cava
Correct Answer: c. The vena cava
Response The vena cava has the most rapid rate of flow. Arterioles don’t offer
Feedback: the most rapid blood flow. Capillaries are composed of a single
thickness of endothelial cells attached to a protein network called the
basement membrane and don’t offer the most rapid blood flow. A
venule begins where the arteriole ends and doesn’t offer the most
rapid blood flow.

Pernicious anemia is caused by a lack of
Selected Answer: b. intrinsic factor.
Correct Answer: b. intrinsic
factor.
Response The fundamental defect causing pernicious anemia is the lack of
Feedback: intrinsic factor. Without it, vitamin B12 cannot be absorbed. Iron
deficiency does not lead to pernicious anemia. Rather, it is the
most common cause of anemia and is the result of unavailability of
iron for hemoglobin synthesis. Pernicious anemia and folate
deficiency are similar in etiology. Both are caused by a disruption
in DNA synthesis of blast cells in bone marrow. Erythropoietin is
necessary for the production of red cells.

Two of the most serious oncology emergencies associated with non-Hodgkin
lymphoma are obstruction of the superior vena cava and compression of the spinal
cord.

, Selected Answer: a. True
Correct Answer: a. True
Response Compression of the spinal cord is one of the two most serious
Feedback: oncology emergencies associated with non-Hodgkin
lymphoma.
Question 4

The most common primary immune deficiency that affects only B cells
is Selected Answer: d. Bruton agammaglobulinemia.
Correct Answer: c. selective IgA.
Response The most common B-cell primary immunodeficiency disorder is
Feedback: selective IgA deficiency. This disorder affects 1:2000 persons.
DiGeorge is a T-cell primary immune deficiency. Bruton
agammaglobulinemia is not the most common primary immune
deficiency affecting B cells; frequency of disease is 1:250,000 males.
Females are carriers. Wiskott–Aldrich affects both T cells and B cells.
Question 5

The effects of histamine release include
Selected Answer: c. increased vascular
permeability. Correct Answer: c. increased
vascular permeability.
Response Histamine release leads to increased vascular permeability, which
Feedback: fosters fluid movement out of capillaries and into tissues leading to
the edema common in type I hypersensitivity. Histamine leads to
bronchoconstriction, increased gut permeability, and vasodilation
(not vasoconstriction).
