Principles of Infection Control
| Question | Answer |
|---|---|
| antiseptics | Tending to inhibit the growth and reproduction of microorganisms |
| bactericidal | Destructive to Bacteria |
| bacteriostatic | Tending to restrain bacteria growth |
| cohorting | Collection or sampling of individuals who share a common characteristic, as members of the same age or same sex, or those sharing a common infection |
| contact precautions | Safeguards designed to reduce the risk of transmission of epidemiologically important microorganisms by direct or indirect contact |
| disinfection | Process of destroying at least the vegetative phase of pathogenic microorganisms by physical or chemical means |
| droplet nuclei | Residue of evaporated water droplets; due to their small size (.5 to 12 mm) droplet nuclei can remain suspended in the air for long periods of time |
| droplet precaution | safeguards designed to reduce the risk of droplet transmission of infectious agents |
| fomiles | non living materials, such as bed linens or equipment, which may transmit pathogenic organisms to a person who comes into contact with the object |
| Healthcare Associated Infections (HAI) | Infections that patients acquire during the course of receiving medical treatment |
| Healthcare Infection Control Practice Advisory Committee (HICPAC) | Committee that sets guidelines for infectious control practices in various health care settings |
| High Efficiency Particulate Air/Aerosol Filters (HEPA) | A filter with an efficiency rate of 99.97% used on various respiratory equipment such as ventilators, that prevent the spread of infection |
| immunocompromised host | immunodeficient patient highly susceptible to infection |
| nosocomial infections | infection acquired after hospitalization |
| Occupational Safety and Health Administration (OSHA) | A branch of the US department of labor responsible for regulation pertaining to on-the-job safety |
| respiratory hygiene/cough etiquette | The strategy of preventing transmission of respiratory infections at the first point of contact within a health care setting such as physicians' offices |
| sporicidal | Destructive to the spore of bacteria |
| standard precautions | Guidelines recommended by the centers for disease control and prevention to reduce the risk of transmission of blood-borne and other pathogens in hospitals. |
| sterilization | Complete destruction of all microorganisms, usually by heat/ chemical means |
| surveillance | (bacteriologic) ongoing process designed to ensure that infection control procedures are working, generally involves equipment, microbiology identification, and epidemiological investigation |
| virucidal | An agent that destroys or inactivates viruses |
| sodium hypochlorite | Another name for a fast-acting, inexpensive, broad-spectrum disinfectant known as bleach |
| steam sterilization | Most common, efficient and easiest form of sterilization method that uses moist heat in the form of steam under pressure |
| personal protective equipment | variety of barriers and respirators used alone or in a combination to protect mucous membranes, skin and clothing from contact with infectious agents |
| airborne isolation | Isolation techniques intended to reduce the risk of selected infectious agents transmitted by "small droplets" of aerosol particles |
| standard precautions | Precautions applied to the care of all patients in all health care settings |
| extended precautions | This is for patients who are known or suspected to be infected with pathogens that require additional control measure to prevent transmission |
| flash sterilization | An acceptable practice for processing cleaned patient care items that cannot be packaged, sterilized, and stored before use which is done by a process of modification of conventional steam sterilization |
