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


In the case of gross contamination what would this mean for the patient

It would mean starting the patient on intravenous antibiotics
