MULTIPLE CHOICE

 

1. The nurse is teaching about changes in the immune system that result from the aging process. Which change should the nurse include?

a.	Thickened skin
b.	Reduced ciliary action
c.	Thinned periosteum
d.	Reduced saliva

 

 

ANS:  B

Reduced ciliary action in the respiratory and gastrointestinal tracts results in a decrease in the removal of harmful organisms.

2. The nurse differentiates the humoral response from the cell-mediated response. Which statement about cell-mediated response is true?

a.	The sensitized lymphocytes attack the cell for which they were sensitized.
b.	Cells produce new antibodies.
c.	The response does not occur until the white blood cell (WBC) count rises.
d.	There is a systemic response of fever and malaise.

 

 

ANS:  A

Cell-mediated response occurs when the specifically antigen-sensitized T lymphocytes attack whole cells, infectious organisms, and nonliving matter such as pollen and dust.

3. Which type of lymphocytes actually produces either sensitized lymphocytes or antibodies?

a.	B lymphocytes
b.	T cells
c.	Suppressor T cells
d.	Stem cells

 

 

ANS:  A

The B-cells secrete immunoglobulins that are called antibodies.

4. The nurse explains to a patient with a painful toe that the pain is related to the inflammatory response. What process causes this discomfort?

a.	Swelling, which compresses nerves.
b.	Enzyme release, which irritates the area.
c.	Acidic waste from the destroyed cells.
d.	Heat of lysis, which affects the nerves.

 

 

ANS:  A

The swelling brought on by the fluid that collects at the site compresses nerves, causing pain.

5. The nurse is reviewing laboratory results of a patient who had surgery 2 days ago. The nurse notes that the C-reactive protein is elevated. What potential problem does this finding indicate?

a.	Impending infection
b.	Possible hemorrhage
c.	A drug allergic reaction
d.	Fluid deficit

 

 

ANS:  A

Since inflammation is an early response to infection, an elevation of the C-reactive protein (which elevates with inflammation) is an indicator of possible impending infection. C-reactive protein is not directly related to hemorrhage, drug reaction, or fluid deficit.
