NURS 5315 IMMUNE practice test
questions
A hypersensitivity reaction that produces an allergic response is called:
a. Hemolytic shock
b. Anaphylaxis
c. Necrotizing vasculitis
d. Systemic erythematosus - ANS-ANS: B
Examples of systemic anaphylaxis are allergic reactions to beestings, peanuts, and fish. The
other options are not accurate examples of hypersensitivity
\A person with type O blood is considered to be the universal blood donor because type O
blood contains which of the following?
a. No antigens
b. No antibodies
c. Both A and B atigens
d. Both A and B antibodies - ANS-ANS A
Because individuals with type O blood lack both types of antigens, they are considered
universal donors, meaning that anyone can accept their red blood cells. Type O individuals,
who have neither A or B antigen but have both anti-A and anti-B antibodies, cannot accept
blood from any of the other three types.
\A person with type O blood is likely to have high titers of which anti-antibodies?
a. A
b. B
c. A and B
d. O - ANS-ANS C
type O individuals neither A or B antigen but have both anti-A and anti-B antibodies and
therefore cannot accept blood from any of the other three types
\Blood transfusion reactions are an example of:
a. Autoimmunity
b. Alloimmunity
c. Homoimmunity
d. Hypersensitivity - ANS-ANS B
Only Alloimmunity (also termed isoimmunity) occurs when the immune system of one
individual produces an immunologic reaction against tissues of another individual
\Considering the effects of nutritional deficiencies on the immune system, severe deficits in
calories and protein lead to deficiencies in the formation of which immune cells?
, a. B cells
b. T cells
c. Natural killer cells
d. Neutrophils - ANS-ANS B
severe deficits in calorie or protein intake lead to deficiencies in T-cell function and numbers
\Deficiencies in which element can produce depression of both B- and T-cell function?
a. Iron
b. Zinc
c. Iodine
d. Magnesium - ANS-ANS B
of the options available, only deficient zinc intake can profoundly depress T- and B-cell
function
\During an IgE-mediated hypersensitivity reaction, the degranulation of mast cells is a result
of which receptor action?
a. Histamine bound to H2
b. Chemotactic factor binding to the receptor
c. Epinephrine bound to mast cells
d. Acetylcholine bound to mast cells - ANS-ANS: A
Histamine bound to H2 results in the degranulation of mast cells during an IgE-medicated
hypersensitivity reaction. The other options do not cause this reaction.
\During an IgE-mediated hypersensitivity reaction, what causes bronchospasm?
a. Bronchial edema caused by the chemotactic factor of anaphylaxis
b. Bronchial edema caused by binding of the cytotropic antibody
c. Smooth muscle contraction caused by histamine bound to H1 receptors
d. Smooth muscle contraction caused by histamine bound to H2 receptors - ANS-ANS C
During an IgE-mediated hypersensitivity reaction, only smooth muscle contraction caused by
histamine bound to H1 receptors results in bronchospasms.
\During an IgE-mediated hypersensitivity reaction, which leukocyte is activated?
a. Neutrophils
b. Monocytes
c. Eosinophils
d. T lymphocytes - ANS-ANS C
Of the options provided, only eosinophils are activated during IgE-mediated hypersensitivity
reactions
\Graves disease is a result of:
a. Increased levels of circulating immunoglobulins
b. The infiltration of the thyroid with T lymphocytes
