NURS 505 EXAM 4 (CHAPTERS 7, 10, 14, 15, 16 & 18) STUDY GUIDE 2026/2027 | PRACTICE
QUESTIONS & VERIFIED ANSWERS
A client is experiencing an inflammatory response following an injury. What assessment finding
would confirm the role of thromboxane’s in the inflammatory process?
a) Bleeding has stopped at the injury site
b) The skin surrounding the injury site has become reddened
c) The client's pain is steadily decreasing
d) The client's heart rate and blood pressure have risen - correct answer ✔✔a) bleeding has
stopped at the injury site
Platelet aggregation and blood clotting are the result of the action of thromboxanes. They have
no effect on pain or vital signs. They cause vasoconstriction, which would be more associated
with pallor than redness.
A nurse is caring for a client who has undergone organ transplant surgery. The client asks the
nurse what antibodies are. What is the best response by the nurse?
a) Body's ability to recognize and destroy specific pathogens
b) Body's ability to prevent infectious diseases
c) Any foreign substance or molecule entering the body that stimulates an immune response
d) A protein substance that the body produces in response to an antigen - correct answer ✔✔d)
a protein substance that the body produces in response to an antigen
An antibody is a protein substance that the body produces in response to an antigen. Immunity
is the body's ability to recognize and destroy specific pathogens and to prevent infectious
diseases. An antigen is any foreign substance or molecule entering the body that stimulates an
immune response.
, Once a person has been exposed to a particular antigen and a repeat exposure occurs, what
stimulates a quicker immune response?
a) Immunity
b) Macrophages
c) Memory T cells
d) Antibodies - correct answer ✔✔c) Memory T cells
The memory T and B lymphocytes that are generated remain in the body for a longer time and
can respond more rapidly on repeat exposures to an antigen related to their acquired memory.
A client became ill with an influenza virus several days ago. Today, the client describes being
free of symptoms. What component of the immune system will be predominant today?
a) Suppressor T cells b)Complement proteins c)Interleukins
d) Cytokines - correct answer ✔✔a) Suppressor T cells
Suppressor T cells play an important role in limiting the immune response and preventing it
from become too aggressive or too prolonged. Complement proteins, interleukins, and
cytokines would be more significant during the active response to the pathogens.
Which client would be most likely to benefit from the administration of interferon therapy?
a) A client with leukemia
b) A client with tuberculosis
c) A premature neonate
d) A client with asthma and seasonal allergies - correct answer ✔✔a) a client with leukemia
