Infection Control Flashcards
aerobic
requiring oxygen in order to live and grow
anaerobic
not requiring oxygen in order to live and grow, able to thrive in the absence of oxygen
antisepsis
aseptic control that inhibits, retards growth of, or kills pathogenic organisms; not effective against spores and virsuses
asepsis
being free from infection
autoclave
piece of equipment used to sterilize articles by way of steam under pressure and/or dry heat
bacteria
one-celled microorganism, some of which are beneficial and some of which cause disease
boiling water
method of aseptic control that disinfects but does not sterilize, or kill spores and viruses
cavitation
the cleaning process employed in an ultrasonic unit; bubbles explode to drive cleaning solution onto article being cleaned
chain of infection
factors that lead to the transmission or spread of disease
chemical disinfection
A process that destroys or kills pathogenic organisms.
clean
free from organisms causing disease
communicable disease
disease that is transmitted from one individual to another
contaiminated
containing infection or infectious organisms or germs
disinfection
aseptic-control method that destroys pathogens but does not usually kill spores and viruses
endogenous
produced from within; due to internal causes
exogenous
produced from without; due to external causes
fungi
group of simple, plantlike animals that live on dead organic matter
isolation
method or technique of caring for persons who have communicable diseases
microorganism
small, living plant or animal not visible to the naked eye
nonpathogens
a microorganism that is not capable of causing a disease
nosocomial
pertaining to or originating in a health care facility such as a hospital
opportunistic
Microorganisms that are normal residents of a host but can cause illness when the host’s defenses are weakened by such factors as poor nutrition or a recent bout with the flu
pathogens
disease-producing organisms
protective isolation
technique used to provide care to patients requiring protection from organisms in the environment
protozoa
microscopic, one-celled animals often found in decayed materials and contaminated water
rickettsiae
parasitic microorganisms that live on other living organisms
sterile
free of all organisms, including spores and viruses
sterile field
an area that is set up for certain procedures and is free from all organisms
sterilization
process that results in total destruction of all microorganisms; also, surgical procedure that prevents conception of a child
ultrasonic
piece of equipment that cleans with sound waves
universal precautions
recommendations that must be followed to prevent transmission of pathogenic organisms by way of blood and body fluid
viruses
one of a large group of very small microorganisms, many of which cause disease
