Symptoms are localized to the area of exposure, usually the back of the hands.
Which cells present the antigen to T cells and initiate the immune response?
Macrophages
A nurse is working in a dermatology clinic with clients who have allergies. What is the most important chemical mediator involved in the allergic response?
histamine
The nurse is teaching a group of health care workers about latex allergies. What reaction will the nurse teach the workers to be most concerned about with laryngeal edema?

Autoimmune
The nurse is evaluating a client's complete blood cell count and differential along with the serum immunoglobulin E (IgE) concentration. Which result might indicate that the client has an allergic disorder?
High IgE concentration
Which body substance causes increased gastric secretion, dilation of capillaries, and constriction of the bronchial smooth muscle?
Histamine
A client develops a facial rash and urticaria after receiving penicillin. Which laboratory value does the nurse expect to be elevated?
IgE
An infant is born to a mother who had no prenatal care during her pregnancy. What type of hypersensitivity reaction does the nurse understand may have occurred?

What education should the nurse provide to the patient taking long-term corticosteroids?
