being free from infection

must be followed for by any patients known or suspected to be infected with epidermiologically important microorganisms that can be transmitted by either direct or indirect contact
contaminated
containing infection or infectious organisms or germs
disinfection
aseptic control method that destroys pathogens but does not usually kill spores and viruses
droplet precautions
must be followed by patient known or suspected to be infected with pathogens transmitted by large particle droplets expelled during coughing, sneezing, talking, or laughing

pathogens
disease producing organisms
personal protective equipment
items such as gloves, gowns, masks, protective eyewear,and hair coverings are used to protect the nurse from infectious organisms

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
