NR 507 – IMMUNOLOGY FINAL EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED) 1. Inappropriate immune responses may be because of Correct Answer 1-exaggerated against environmental antigens - allergy - most common 2-misdirected against the host's cells - autoimmunity 3-directed against beneficial foreign tissues like transfusion or transplant - alloimmunity 4-insufficient to protect the host - immune deficiency 2. Hypersensitivity Correct Answer an exaggerated response by the immune system to a particular substance 3. Hypersensitivity reaction can be identified by Correct Answer 1-by the source of the antigen that the immune system is attacking (allergy, autoimmunity, alloimmunity) 2-by the mechanism that causes disease (types I, II, III & IV) 4. Autoimmunity Correct Answer 2 / 7 disturbance of the immunologic tolerance of self-antigens - not recognizing own antigens -can be familial - may not be same disease 5. alloimmunity aka isoimmunity Correct Answer when the immune system of one individual produces a reaction against tissues of another individual. Happens during transfusions, transplanted tissue, or fetus during pregnancy 6. hypersensitivity develops because of Correct Answer 1. an original "insult" which alters immunologic omeostasis 2. the genetic makeup 3. an immunologic process that causes the symptoms of the disease 7. Immunologic homeostasis Correct Answer a steady state of tolerance to self-antigens or lack of immune reaction against environmental antigens 8. Immune mechanisms from hypersensitive reactions Correct Answer type I - immunoglobulin E {IgE}-mediated type II - tissue specific type III - immune complex-mediated type IV - cell-mediated seldom is a disease associated with just one type
