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. REF: p. 159 2. Which patient will develop active immunity? A patient who: a. has natural exposure to an antigen or receives an immunization. b. receives preformed antibodies or T cells from a donor. c. has T cells that become B cells. d. receives immunoglobulin. ANS: A Active immunity occurs either after natural exposure to an antigen or after immunization, not with preformed antibodies or the transformation of T cells into B cells or as a result of receiving immunoglobulin. REF: p. 159 3. An experiment is designed to determine specific cell types involved in cell-mediated immune response. The experimenter is interested in finding cells that attack cells that have specific antigens. Which cells should be isolated? a. Lymphokine-producing cells b. T-cytotoxic cells c. Helper T cells d. Macrophages ANS: B Cell-mediated immunity is driven by T-cytotoxic (Tc) cells that attack antigens directly and destroy cells that bear foreign antigens. Lymphokine-producing cells, helper T cells, and macrophages do not attack antigens directly and destroy cells that bear foreign antigens. REF: p. 159 4.
