Which of the following is an example of immunocompetence?
a. A child that is immune to measles because of an inoculation
b. A person who has seasonal allergies every fall
c. When the symptoms of a common cold disappear in 1 day
d. A neonate having a natural immunity from maternal antibodies
c. When the symptoms of a common cold disappear in 1 day
Immunocompetence is demonstrated by the immune system responding appropriately to a foreign stimulus and the body's integrity is maintained as with cold symptoms that resolve with residual illness.
p. 1962
An anxious patient enters the emergency room with angioedema of the lips and tongue, dyspnea, urticaria, and wheezing after having eaten a peanut butter sandwich. What should be the nurse's first intervention?
a. Apply cool compresses to urticaria
b. Provide oxygen per non-rebreathing mask
c. Cover patient with a warm blanket
d. Prepare for venipuncture for the delivery of IV medication
b. Provide oxygen per non-rebreathing mask
Provision of oxygen is the initial primary intervention. Anaphylaxis may advance very rapidly and the patient may have to be intubated. Covering the patient with a warm blanket is not wrong, but not an initial intervention.
p. 1971
What is the etiology of autoimmune diseases based on?
a. Reaction to a "superantigen"
b. Immune system producing no antibodies at all
c. T cells destroying B cells
d. B and T cells producing autoantibodies
d. B and T cells producing autoantibodies
Autoimmune disorders are failures of the tolerance to "self." B and T cells produce autoantibodies that can cause pathophysiologic tissue damage. Autoimmune disorders may be described as an immune attack on the self and result from the failure to distinguish "self" protein from "foreign" protein.
p. 1974
A patient is admitted with a secondary immunodeficiency from chemotherapy. The nursing plan of care should include provisions for:
a. infection control.
b. supporting self-care.
c. nutritional education.
d. maintaining high fluid intake.

The nurse takes into consideration that when the antigen and antibody react, the complement system is activated which:
a. toughens the cell wall.
b. generates more T cells.

The complement system is a group of plasma proteins that are dormant until there is an antigen-antibody interaction. The proteins destroy the cell membrane and attract phagocytes.
p. 1966
How does normal aging change the immune system?
a. Depresses bone marrow
b. T cells become hyperactive
c. B cells show deficiencies in activity
d. Increase in the size of the thymus
c. B cells show deficiencies in activity
Normal aging causes deficiencies in both B and T cell activation, but the bone marrow is essentially uncompromised. The thymus decreases in size.

a. Cause vasodilation
b. Produce bronchodilation
c. Cause productive coughing
d. Reduction of pulse rate
b. Produce bronchodilation
The drug epinephrine is given in the case of anaphylaxis because it is a quick-acting drug that produces bronchodilation and vasoconstriction, which relieves respiratory distress. The drug can be ordered to be repeated every 20 minutes. The patient may experience an increase in heart rate.
