Flashcards in Concepts And Definitions Deck (13):
What makes an object sterile?
When an object is completely sterile, it is completely free of all living microorganisms including microbial spores
What surfaces are considered potentially contaminated with pathogenic microorganisms
What type of body tissues are normally free of microorganisms
All body tissues, except those that communicate directly with the environment outside the body
What is the contact between a sterile surface or object and a nonsterile item, substance, or entity
Contamination is defined in several ways, #1
It defines an item or surface that was previously sterile but comes in contact with a contaminant, such as a sterile instrument that falls to the floor. The surgeons gloves hand accidentally touches the nonsterile edge of the surgical drape. His glove is contaminated. The scrubbed ST accidentally punctures her glove with a suture needle. The needle is contaminated
Contamination is an event in which?
A sterile item or surface has come in contact with a nonsterile item or surface, for example an infected appendix has ruptured, spilling out into the abdominal cavity
What is gross contamination
The contamination of the surgical wound or sterile field by a highly infective source such as in the wound or sterile field by highly infective source such as in the example just given. Can lead to systemic infection because of the number and type of microorganisms that enter the body
What is one of the foundation principles of aseptic technique is based on
Creating a barrier between the source of contamination and a sterile surface
What prevents a nonsterile surface from touching a sterile surface
A physical barrier
What is produced by the residual effect of ____ used during patient skin prep and the surgical scrub or handrub
Chemical barrier; antiseptics
Distance is another type of barrier.
The distance between a sterile surface and a nonsterile surface increases the risk of contamination decreases
What is aseptic technique based on?
Surgical conscience--that is, the ethical and professional motivation that regulates a professionals behavior regarding disease transmission
