21
Q

Fungicide

A

Destroys fungi

22
Q

Nosocomial

A

Infection inquired within an healthcare facility

23
Q

Pathogen

A

Any microbe capable of causing disease

24
Q

Sepsis

A

Infection, accompanied by fever, caused by pathogen

25
Q

Spore

A

A resistant form of certain types of bacteria that are able to survive in adverse conditions

26
Q

Sterile

A

Rendered free of all microorganisms, including spores

27
Q

Sterilization

A

Destruction of all microorganisms, including spores on inanimate objects and surfaces

28
Q

Strike-through contamination

A

Contamination of a sterile field that occurs through the passage of fluid through or a puncture in a microbial barrier

29
Q

Surgically Clean

A

Mechanically clean and chemically disinfected but not sterile

30
Q

Transient Flora

A

Microbes that reside on the skin surface and are easily removed

31
Q

Vector

A

Living carrier that transmits disease

32
Q

Virucide

A

Agent that destroys viruses

33
Q

Used on tissue

A

Antiseptic

34
Q

Used on inanimate objects

A

Decontaminate, Disinfectant

35
Q

Where on the inside of a paper wrap is it unsterile

A

The 1 inch boarder around the edge

36
Q

What distance should a non sterile individual keep with a sterile field

A

12inches

37
Q

Critical items (for sterilization)

A

Must be sterile prior to use on tissue or within the body

38
Q

Semi critical items (for sterilization)

A

Items that come in contact with microorganisms but no body cavities (Cystoscopes, Colonscopes, Laryngoscopes) Mucous membranes are resistant to spores so items only need to be disinfected

39
Q

Noncritical items

47
Q

Removes particles that mechanical and sterilizer couldn’t reach

A

Ultrasonic cleaner

48
Q

Flash Sterilizer time

A
