Name: ______________________________Department/Institution:____________________________ Immunology Contact hours – 1.25 Goals & Objectives Goals To improve the learner's understanding of how immunology relates to infection control. Objectives • Briefly describe immunology and related terms. • Briefly describes how the immune system works. • Interpret common reports from the Immunology lab. Test 1. Immunology a. Is the study of reactions by a specific group of antigens introduced by a nutrient. b. Is the limited study of an inflammatory response following tissue damage. c. Is the study of all aspects of the immune system including its structure and function, disorders of the immune system, blood banking, immunization and organ transplantation. d. All of the above 2. An antigen is a. A familiar cell within the body. b. Part of the humoral acquired immunity. c. A foreign invader. d. Part of the specific immune system that is derived from the B lymphocytes. 3. The immune system is a. A complex network of specialized cells and organs whose primary job is to protect us from foreign invaders through our innate and acquired immunity. b. Derived from the thymus, bone marrow, spleen, lymph nodes, tonsils, appendix, Peyer’s patches and MALT. c. Primarily dependent on B lymphocytes and T lymphocytes for specific immunity. d. All of the above. 4. T lymphocytes originate from the hematopoietic stem cells but migrate to the thymus and a. Some may eventually evolve into the T helper cell (CD4) which secretes cytokines when activated b. Some may eventually evolve into the T cytotoxic cell (CD8) which destroys virally infected cells. c. Only the T cells can recognize antigens originating from the cells within the host. d. All of the above. - 30 -
Name: ______________________________Department/Institution:____________________________ 5. A pediatric nurse who was exposed to chickenpox in the past 24 hours admits to having an uncertain immunity to the disease and has a negative IgG. Therefore you assume a. She was vaccinated and has waning immunity. b. She had disease and no further action is needed. c. She did not have disease and should be vaccinated plus furloughed 10-21 days after the exposure. d. She did not have disease and be allowed to work if her coworkers have documented immunity to the disease. 6. A 40 yr male who was camping last weekend and is now presenting with erythema migrans measuring 4.5 cm in diameter and his Lyme disease EIA is 0.34, therefore you assume a. He has lyme disease and report it to the health department b. He will need further testing at a later date if this is to meet the case definition for Lyme Disease for reporting c. He had a previous exposure and has immunity d. He does not have Lyme disease and no further testing is needed. - 31 -
