The nurse explains that histamine is released during an anaphylactic reaction and that the action of histamine includes: Standard Text: Select all that apply.
A)Release of IgE antibodies.
B)Smooth muscle contraction.
C)Increased capillary permeability.
D)Vasoconstriction.
E)Red cell destructions

Question

Quizplus · Accepted Answer

Histamine released during an anaphylactic reaction causes smooth muscle contraction, leading to bronchoconstriction, and increased capillary permeability, leading to edema and potentially life-threatening hypotension. Release of IgE antibodies and red cell destruction are not directly caused by histamine during an anaphylactic reaction. Vasoconstriction is not a typical action of histamine during anaphylaxis.
