Question | Answer |
Personal Protective Equipment (PPE) | any of items to protect from transmission of disease: gloves, mask, goggles, gowns |
Surgical Asepsis | destruction of pathogenic organisms so they do not enter the body esp. during surgical procedure |
Mechanical defense | skin, hair are examples of bodies protective mechanisms |
Antibody | substance produced by WBC in response to antigen; destroys the invader |
Chemical defense | sebaceous glands, stomach acids |
Antigen | marker that identifies a cell as being part of the body or NOT |
Inflammatory response | body's reaction to injury, infection, allergy (immune system activated) |
Interferon | chemical produced by WBC responding to pathogen that will stop or slow virus production |
Localized inflammation (signs) | redness, swelling, heat, pain |
Histamine | chemical that causes dilation of blood vessels (part of inflammatory response) |
Passive artificial immunity | Immunity from outside source introduced into patient eg. gamma globulin |
Standard Precautions | guidelines for handling of OPIM (blood, body fluids, infectious organisms) |
Passive natural immunity | immunity acquired from mother to fetus |
Prostaglandins | hormone to stimulate receptors and produce inflammatory response (vasodilation, vascular permeability, platelet response) |
Active artificial immunity | immunity from vaccines |
Phagocytosis | process in which WBC destroy (eat) pathogens, foreign antigens, cellular debris |
Active natural immunity | when body produces immunity when exposed to pathogenic organism (exposed to virus such as cold, flu, etc) |
Medical asepsis | destruction of pathogenic organisms outside of the body |
immunity | protection from disease |
lysozyme | enzyme in tears, saliva and other body secretions to protect against pathogens |
