Disease transmission & infection control
| Question | Answer |
|---|---|
| acquired immunity | immunity that is developed during a person's lifetime |
| infection of short duration that is often severe | acute infection |
| extreme hypersensitivity to a substance that can lead to shock and life threatening respiratory collapse | anaphylaxis |
| disease such as hbv,hcv,or hiv infection that is caused by microorgansims such as viruses or bacteria that are carried in blood | blood borne disease |
| disease causing organisms transferred through contact with blood or other body fluids | blood borne pathogens |
| chain of infection | conditions that all muct be present for infection to occur |
| an infection of long duration | chronic infection |
| condition caused by an infection that can be spread from person to person or through contact with body fluids | communicable disease |
| items such as gloves and patient napkins that may contain potentially infectious body fluids of patients | contaminated waste |
| touching or contact with a patients blood or saliva | direct contact |
| an infection that occurs through mucosal surfaces of the eyes nose or mouth | droplet infection |
| studies of the patterns and causes of diseases | epidemiologic studies |
| waste that poses a danger to umans or to the environment | hazardous waste |
| ability of the body to resist disease | immunity |
| touching or contact with a contaminated surface or instrument | indirect contact |
| disease that is communicable | infectious disese |
| waste that is cabanle of transmitting an infectious disease | infectious waste |
| immunity that is present at birth | inherited immuntiy |
| persistent infection with recurrent symptoms that come and go | latent infectioun |
| immunity that occurs when a person has contracted and is recovering from a disease | naturally acquired immunity |
| any reasonably anticipated skin,eye or mucous memerane contact or percutaneous injury involving lodd or any other potentially infectious materials | occupational exposure |
| guidelines designed to protect employees against occupational exposure to blood borne pathogens | osha blood borne pathogens standard (BBP) |
| disease causing organism | pathogen |
| contact with mucous membranes suchas the eyes or mouth | permucosal |
| items such as protective clothing, masks,gloves, and eyewear used to protect employees | PPE |
| pointed or cutting instruments,including needles , scalpel blades ortodontic wires and endodontic instruments | sharps |
| standard of care designed to protect helathcare providers form pathogens that can be spread by blood or any other body fluid vis excretion or secretion, expand upon the concept of universal precautions | standard precautions |
| guidelines based on treating all human blood and body fluids including salival as potentially infectious | universal precautions |
| strenght of a pathogens ability to cause diseas | virulence |
| the links to the chain of infection are | virulence, number of microorganisms,susceptible host and portal of entry |
| a person who is unable to resist infection by a particular pathogenis know as | a susceptible host |
| what are the portals of entry for airborne pathogens | mouth and nose |
| what are the portals of entry for blood borne pathogens | break in the skin caused by a needle stick a cut or even a human bite, can also occur through the mucous membranes of the nose and oral cavity |
| what type of infection is in which the microorganism is present for a long duration,some may persist for life. the person may be asymptomatic | chronic infection |
| what agency is it that its role is to issue specific recommendations that are basd on sound scientific evidence for health related matters | CDC |
| which agency released the guidelines for infection control in dental healthcare settings 2003 | CDC |
| what is the most important infection control law in dentistry | BBP |
| how often should the exposure control plan be updated | annually |
| how long is the employer to keep confidential medical records for each employee | 30 years |
| in most states contaminated waste is disposed of as what | general waste |
