Chapter 4_Principles of infection control.txt

Tending to inhibit the growth and reproduction of microorganisms

Destructive to Bacteria

Tending to restrain bacteria growth

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

Safeguards designed to reduce the risk of transmission of epidemiologically important microorganisms by direct or indirect contact

Process of destroying at least the vegetative phase of pathogenic microorganisms by physical or chemical means

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

safeguards designed to reduce the risk of droplet transmission of infectious agents

non living materials, such as bed linens or equipment, which may transmit pathogenic organisms to a person who comes into contact with the object

Infections that patients acquire during the course of receiving medical treatment

Committee that sets guidelines for infectious control practices in various health care settings

A filter with an efficiency rate of 99.97% used on various respiratory equipment such as ventilators, that prevent the spread of infection

immunodeficient patient highly susceptible to infection

Infection acquired after hospitalization

A branch of the US department of labor responsible for regulation pertaining to on-the-job safety

The strategy of preventing transmission of respiratory infections at the first point of contact within a health care setting such as physicians' offices

Destructive to the spore of bacteria

Guidelines recommended by the centers for disease control and prevention to reduce the risk of transmission of blood-borne and other pathogens in hospitals. Standard precautions apply to (1) blood (2) all body fluids, secretions, excretions, excluding sweat, regardless of whether they contain blood (3) non-intact skin (4) mucous membranes

Complete destruction of all microorganisms, usually by heat/ chemical means

(bacteriologic) ongoing process designed to ensure that infection control procedures are working, generally involves equipment, microbiology identification, and epidemiological investigation

An agent that destroys or inactivates viruses

Another name for a fast-acting, inexpensive, broad-spectrum disinfectant known as bleach

Most common, efficient and easiest form of sterilization method that uses moist heat in the form of steam under pressure

variety of barriers and respirators used alone or in a combination to protect mucous membranes, skin and clothing from contact with infectious agents

Isolation techniques intended to reduce the risk of selected infectious agents transmitted by "small droplets" of aerosol particles

Precautions applied to the care of all patients in all health care settings

This is for patients who are known or suspected to be infected with pathogens that require additional control measure to prevent transmission

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
