Answer to Question 1

ANS: D
Giving analgesic/antipyretic medications before or shortly after vaccines can reduce the immune response, so giving them to prevent pain or fever is not recommended. Children do remember pain, and it is important to provide other comfort measures and to give the injections rapidly. Small needles cause less discomfort, and it is important to reassure the parents about this; however, it is more important to explain why acetaminophen is not recommended. Topical anesthetics are useful before giving the injections, not afterwards.

Answer to Question 2

ANS: B, C, E
The autoimmune response causes the immune system to attack the body's own cells. The hypersensitivity response, mediated by IgE, causes the release of harmful chemical mediators. Recognition of MHC molecules as nonself in a transplanted organ can cause organ rejection. Activation of the complement system causes a cascade of reactions that assist in the immune response. Opsonization is a process that assists with phagocytosis.
