A client has been hospitalized for diagnostic testing. The client has just been diagnosed with multiple sclerosis, which the physician explains is an autoimmune disorder. How would the nurse explain an autoimmune disease to the client?
A) A disorder where the body has too many immunoglobulins.
B) A disorder where histocompatible cells attack the immunoglobulins.
C) A disorder where killer T cells and autoantibodies attack or destroy natural cells—those cells that are "self."
D) A disorder where the body does not have enough immunoglobulins.
C
Feedback:
Autoimmune disorders are those in which killer T cells and autoantibodies attack or destroy natural cells—those cells that are "self." Autoantibodies, antibodies against self-antigens, are immunoglobulins. They target histocompatible cells, cells whose antigens match the person's own genetic code. Autoimmune disorders are not caused by too many or too few immunoglobulins, and histocompatible cells do not attack immunoglobulins in an autoimmune disorder.
