Endothelial - ANS-Mast cell You sprained your ankle and are told to take ibuprofen to reduce the inflammation. What is the mechanism of action for this drug? A. Blocks chemokines B. Enhances mast cell activation C. Blocks Prostaglandins D. The mechanism of action is unknown - ANS-Block prostaglandins The activation of complement induces all of the following except: A. Coagulation B. Opsonization C. Chemotaxis D. Cell lysis - ANS-Coagulation Which of the following does not explain why multiple pathways are needed for the activation and suppression of chemical mediators A. Healing requires multiple chemical mediators B. The chemical mediators are so potent C. The response must be overzealous to be effective D. Autoimmunity can occur if unregulated - ANS-The response must be overzealous to be effective Although against your better judgment, you squeezed an acne pustule on your face. Now you notice a clear fluid seeping from the opening. What is this clear fluid? A. Pus B. Water C. Exudate D.
