The use of heat to kill all microorganisms, except spores
Compounds that contain a positive electrical charge. They exhibit germicidal properties.
A chemical which kills most pathogenic organisms, but does not kill spores.
A solution which inhibits the growth of bacteria. It is usually used topically and only on animate objects.
The length of time a disinfectant can be properly stored after which it must be discarded.
Compounds that have a negative electrical charge. They form a large group of synthetic detergents.
The destruction of nearly all pathogenic microorganisms on an inanimate surface.
Relating to the destruction of bacteria
The length of time (or number of uses) after which the efficiency of a disinfectant is diminished.
A process by which all forms of microbial life are destroyed.
Items that are introduced directly into the bloodstream or other normally sterile areas of the body are classified as:
Iodophors are a member of this chemical family:
Intermediate to low level disinfectants
Phenolics are classified as:
Thermal disinfection is accomplished using:
How long must alcohol remain in wet contact with an item to achieve a reasonable level of disinfection?
Which of the following would be the best choice for high level disinfection of instruments?
Are intermediate-level disinfectants that have similar elements possessing some unique properties.
A high-level disinfectant used for semi-critical devices such as endoscopes and ultrasonic probes used in radiology
Relatively new high-level disinfectant that provides a fast and effective way to disinfect a wide range of instruments and endoscopes.
High level disinfection
Process that utilizes a sterilant for a shorter contact time than that used for sterilization, and that kills all microbial organisms but not necessarily large numbers of bacterial spores.
Intermediate level disinfection
Process that utilizes an agent that kills viruses, mycobacteria, fungi,and vegetative bacteria, but not bacterial spores.
Low level disinfection
Process that utilizes an agent that kills vegetative forms of bacteria, some fungi, and lipid viruses.
Quaternary Ammonium Compounds
This low-level disinfectant is often used in environment sanitation such as floors, walls, and furniture .
This common disinfectant has been in use for several years. It is often used to disinfectant equipment.
Items need to be cleaned before they are sterilized, but they do not need to be cleaned before they are disinfected.
When liquid chemicals are labeled as both a high-level disinfectant and a sterilant, the time required to achieve sterilization is longer than the time required to achieve high-level disinfection.
Mechanical washers and washer-decontaminators are regulated by the CDC.
All liquid disinfectants are capable of sterilization if their exposure time is increased.
Log books should be maintained when using Glutaraldehyde and OPA
