The nurse knows that Type IV Hypersensitivity Reaction involves which of the following?
Histamine release
T-lymphocyte memory cells
Immunosuppression
Antigen/antibody interaction
The Correct Answer is B
Histamine release: Histamine release is characteristic of Type I hypersensitivity reactions (immediate hypersensitivity) rather than Type IV.
T-lymphocyte memory cells: Type IV hypersensitivity is a delayed response mediated by T-lymphocytes, not antibodies.
Immunosuppression: Immunosuppression is not directly related to hypersensitivity reactions.
Antigen/antibody interaction: This is characteristic of Types I, II, and III hypersensitivity reactions, not Type IV.
