B. Hypersensitivity type II
C. Hypersensitivity type III
D. Hypersensitivity type IV
A. Hypersensitivity type IV
- Type IV hypersensitivity is mediated by T cells. Hypersensitivity types I, II,
and III are mediated by antibodies produced by B lymphocytes.
A severe life-threatening type I hypersensitivity reaction is

D. Hives
C. Anaphylaxis
,What is the pathophysiologic abnormality underlying systemic lupus
erythematosus (SLE)?

B. Immunosuppression
C. Immune deficiency
D. Autoimmunity
D. Autoimmunity
- SLE is a type III hypersensitivity reaction caused by autoantibody
production and occurs when the immune system recognizes a person's
own cells ("self") as foreign and mounts an immune response that injures
