Vocab #3 Flashcards
closed gloving
method of putting on sterile gloves in which the hands are kept hidden within the sleeves of a sterile gown during gloving
open gloving
method of putting on sterile gloves when the person is not wearing a sterile gown or the hands are protruding through the ends of the gown sleeves
immediate use steam sterilization (IUSS) or flash sterilization
emergency sterilization in which the instrument is placed unwrapped in an autoclave and taken directly to surgery following sterilization
fenestration
to make an opening
scrub
applying an antiseptic to reduce an animal’s skin normal flora in preparation for a sterile procedure
sterile
a complete absence of microbes and has undergone a cleaning process to achieve this state
non-sterile
may or may not be contaminated with pathogens
sterile field
an area that has been prepared for the use of sterile equipment
it includes the area around the wound, incision site, or body orifice into which an instrument or catheter will be passed and also includes the area covered by sterile drapes and the sterile region of properly attired personnel
sterile technique
creating a sterile field and working within by not contaminating it with non-sterile objects
strike-through
when fluid penetrates a surgical drape or gown
it creates a pathway for for organisms to invade the sterile field
instrument milk
milky lubricant solution used for the protection of surgical instruments from corrosion and rusting
antiseptic
an antimicrobial agent that kills or inhibits the growth of microorganisms on the external surfaces of the body
autoclave
a machine that uses pressurized steam to sterilize objects
EO sterilization
ethylene oxide is a gaseous substance used as a sterilant for instruments and articles that would be damaged by steam sterilization
disinfection
application of an agent that has the ability of destroying or inhibiting the growth of microbes
only use on inanimate objects
sterilization
process to rid an object of all living microbes
microbe
a living organism too small to be seen with the naked eye
prion
a small proteinaceous infectious disease-causing agent that is believed to be the smallest infectious particle
neither bacterial nor fungal nor viral and contains no genetic material
virus
an ultramicroscopic, metabolically inert, infectious agent that replicates only within the cells of living hosts, mainly bacteria, plants, and animals
composed of an RNA or DNA core, a protein coat, and in more complex types, a surrounding envelope
airborne transmission
the passage of microorganisms suspended in the air on water droplets or dust particles that enter the host by inhalation
bacteriostatic
arresting the growth or multiplication of bacteria
colonization
the presence and multiplication of microorganisms without tissue invasion or damage
the infected individual demonstrates no signs or symptoms of infection, while the potential to infect others still exists
infectious agent
a microbial organism with the ability to cause disease
the greater the organism’s virulence (ability to grow and multiply), invasiveness (ability to enter tissue), and pathogenicity (ability to cause disease), the greater the possibility that the organism will cause an infection
infectious agents are bacteria, viruses, fungi, and parasites
nosocomial infection
an infection acquired during hospitalization
vehicle of transmission
the transfer of microorganisms by way of contaminated items
infection
relationship between a parasite and its host, a result
