Immunity NCLEX style questions with correctanswers
How does your immune system know which cells to attack and which
cells are part of your own body? Correct Answer-Your immune system
can recognize cells based on the proteins present on the surface of cells.
Viruses, bacteria, and other foreign cells are recognized as being
different from your own cells and are attacked by your immune system.
Sometimes, one of your own cells changes, or mutates, giving the cell
the ability to multiply continuously. Such mutations often are the cause
of cancer. Your immune system has the ability to recognize mutated
cells and attack them before they can grow into a tumor.
The nurse is planning discharge teaching for a client who has a
splenectomy. Which statement does the nurse include in this client's
teaching plan?
a. "Avoid crowds and people who are sick."
b. "Do not eat raw fruits or vegetables."
c. "Avoid environmental allergens."
d. "Do not play contact sports." Correct Answer-ANS: A
The spleen is the major site of B-lymphocyte maturation and antibody
production. Those who undergo splenectomies for any reason have a
decreased antibody-mediated immune response and are particularly
susceptible to viral infections. Eating raw fruits and vegetables places
the client at risk for bacterial infections. The body responds to
environmental allergens with an unspecific inflammatory process. The
client is not at risk for bleeding or injury due to contact sports.
,The nurse notes that the client has a "left shift of their wbc count" which
lab result supports this conclusion? Correct Answer-The bands
outnumber of segmented neutrophils.
A nurse has educated a client on an epinephrine auto-injector (EpiPen).
What statement by the client indicates additional instruction is needed?
a. "I don't need to go to the hospital after using it."
b. "I must carry two EpiPens with me at all times."
c. "I will write the expiration date on my calendar."
d. "This can be injected right through my clothes." Correct Answer-
ANS: A
Clients should be instructed to call 911 and go to the hospital for
monitoring after using the EpiPen. The other statements show good
understanding of this treatment.
What is a left shift? Correct Answer-An increase in neutrophil
precursors (eg, band cells, metamyelocytes) with or without
neutrophilia, usually from infection or inflammation
Which manifestations or processes of inflammation are caused
specifically by blood vessel dilation?
a. Increased production and migration of leukocytes
b. Phagocytosis and fever
c. Warmth and redness
d. Swelling and pain
e. None of above Correct Answer-ANS: C
,Dilated blood vessels increase blood flow to an area, leading to
increased warmth and color in that area. Dilation alone does not result in
swelling. Swelling results from increased capillary permeability.
Why is the inflammatory response alone insufficient to provide complete
protection against infection?
a. It only responds to tissue injury and not to invasion by
microorganisms.
b. It is nonspecific and no long-lasting immunity is generated by
inflammation alone.
c. When the inflammatory response is prolonged, it can cause serious
tissue damage.
d. The body is not capable of synthesizing antibodies at the same time
that inflammatory processes are active.
e. None of above Correct Answer-ANS: B
The cells that provide the protection of inflammation, the neutrophils
and the macrophages, have no "memory" to aid them in mounting a
faster or stronger response to an invading microorganism upon repeated
or subsequent exposure. Without antibody-mediated immunity and cell-
mediated immunity to augment the inflammatory response, humans
remain susceptible to reinfection by the same microorganism over and
over again.
Correct Answer-
Which cell types provide protective responses during inflammation?
a. Macrophages and neutrophils
, b. Erythrocytes and platelets
c. Eosinophils and basophils
d. Natural killer cells Correct Answer-A Macrophages and neutrophils
initiate and complete phagocytosis against invading microorganisms,
providing the body with protection against infection. Natural killer cells
are not particularly active during inflammation. Eosinophils and
basophils are responsible for vascular changes, not protection.
Erythrocytes and platelets have no direct roles in inflammation.
Which condition or health problem demonstrates inflammation without
invasion?
a. Allergic rhinitis
b. Viral hepatitis
c. Osteoarthritis
d. Cellulitis
e. None of above Correct Answer-C
Osteoarthritis is a "wear and tear" disorder that mechanically causes
tissue damage. All the other disorders represent invasion by non-self
proteins such as pollens, viruses, and bacteria.
Which of the following phrases BEST describes the inflammatory
process?
a. The body's response to an infectious process.
b. An abnormal event that accompanies selected disease processes.
c. A normal body response to cell and tissue injury and death.
