Answer to Question 1

ANS: A, C, D
Type I reactions are mediated by immunoglobulin E (IgE) and include hay fever, anaphylaxis, and allergic asthma. Type III reactions consist of immune complexes that form and deposit in the walls of blood vessels. Type IV reactions include responses to poison ivy exposure, positive tuberculosis tests, and graft rejection. Type II reactions are mediated by immunoglobulin G, not IgM. Type V reactions include Graves' disease and B-cell gammopathies.

Answer to Question 2

ANS: B
Antihistamines can cause drowsiness, so for the client's safety, he or she should be instructed to call for assistance prior to trying to get up. Hyperglycemia and tachycardia are side effects of sympathomimetics. Fluid and sodium retention are side effects of corticosteroids.
