NSG 5003 Week 2 Study Guide Chapter 7: Innate Immunity: Inflammation 1. Which action is a purpose of the inflammatory process? a. To provide specific responses toward antigens b. To lyse cell me... mbranes of microorganisms c. To prevent infection of the injured tissue d. To create immunity against subsequent tissue injury 2. How do surfactant proteins A through D provide innate resistance? a. Initiate the complement cascade. c. Secrete mucus. b. Promote phagocytosis. d. Synthesize lysosomes. 3. Which secretion is a first line of defense against pathogen invasion that involves antibacterial and antifungal fatty acids, as well as lactic acid? a. Optic tears c. Sweat gland perspiration b. Oral saliva d. Sebaceous gland sebum 4. Which bacterium grows in the intestines after prolonged antibiotic therapy? a. Lactobacillus c. Clostridium difficile b. Candida albicans d. Helicobacter pylori 5. What causes the edema that occurs during the inflammatory process? a. Vasodilation of blood vessels c. Endothelial cell contraction b. Increased capillary permeability d. Emigration of neutrophils 6. What process causes heat and redness to occur during the inflammatory process? a. Vasodilation of blood vessels c. Decreased capillary permeability b. Platelet aggregation d. Endothelial cell contraction 7. Activation of the classical pathway begins with: a. Viruses c. Mast cells b. Antigen-antibody complexes d. Macrophages 8. What plasma protein system forms a fibrinous meshwork at an inflamed site? a. Complement c. Kinin b. Coagulation d. Fibrinolysis 9. Which component of the plasma protein system tags pathogenic microorganisms for destruction by neutrophils and macrophages? a. Complement cascade c. Kinin system b. Coagulation system d. Immune system 10. What is the vascular effect of histamine released from mast cells? a. Platelet adhesion c. Vasodilation b. Initiation of the clotting cascade d. Increased endothelial adhesiveness 11. What is an outcome of the complement cascade? a. Activation of the clotting cascade b. Prevention of the spread of infection to adjacent tissues c. Inactivation of chemical mediators such as histamine d. Lysis of bacterial cell membranes 12. The function of opsonization related to the complement cascade is to: a. Tag of pathogenic microorganisms for destruction by neutrophils and macrophages. b. Process pathogenic microorganisms so that activated lymphocytes can be created for acquired immunity. c. Destroy glycoprotein cell membranes of pathogenic microorganisms. d. Promote anaphylatoxic activity, resulting in mast cell degranulation. 13. In the coagulation (clotting) cascade, the intrinsic and the extrinsic pathways converge at which factor? a. XII c. X b. VII d. V 14. Which chemical interacts among all plasma protein systems by degrading blood clots, activating complement, and activating the Hageman factor? a. Kallikrein c. Bradykinin b. Histamine d. Plasmin 15. The chemotactic factor affects the inflammatory process by: a. Causing vasodilation around the inflamed area b. Stimulating smooth muscle contraction in the inflamed area c. Directing leukocytes to the inflamed area d. Producing edema around the inflamed area 16. What affect does the process of histamine binding to the histamine-2 (H2) receptor have on inflammation? a. Inhibition c. Acceleration b. Activation d. Termination 17. Frequently when H1 and H2 receptors are located on the same cells, they act in what fashion? a. Synergistically c. Antagonistically b. Additively d. Agonistically [Show More]
