ANS: B Innate immunity is present at birth, and is considered the body’s first line of defense....

Test Bank: Alterations in Immunity Huether: Understanding Pathophysiology, 7th Edition MULTIPLE CHOICE 1. When a patient asks the nurse what hypersensitivity is, how should the nurse respond? Hypersensitivity is best defined as: a. a reduced immune response found in most pathologic states. b. a normal immune response to an infectious agent. c. an excessive or inappropriate response of the immune system to a sensitizing antigen. d. antigenic desensitization.

Test Bank: Adaptive Immunity Huether: Understanding Pathophysiology, 7th Edition MULTIPLE CHOICE 1. Which of the following is responsible for initiating clonal selection? a. T cells b. B cells c. Antigens d. Lymphocytes ANS: C The lymphocytes remain dormant until an antigen initiates clonal selection. T cells do not initiate clonal selection. B cells are antibodies. Lymphocytes are released into the circulation as immature cells that react with antigens. 2. Which patient will de...

Test Bank: Stress and Disease Huether: Understanding Pathophysiology , 7th Edition MULTIPLE CHOICE 1. A female student is driving to school when another driver nearly hits her.
