Q

who proposed an additional category for the inanimate surface category? when was it? what was it?

A

microbiologist at CDC (Centers for Disease Control and Prevention), 1991, Environmental surfaces

17
Q

they do not make a direct contact with a person’s skin

A

environmental surfaces

18
Q

it is a classification of chemical germicides or disinfectants according to their activity level

A

Spaulding’s classification of chemical germicides
by activity level

19
Q

Also known as SPOROCIDES

A

High-level disinfection

20
Q

Also known as HOSPITAL-GRADE DISINFECTANTS or SANITIZERS

A

Low-level disinfection

21
Q

Capable of sterilization when the contact time is relatively long (6-10 hours) depending on the chemical germicide being used. what disinfection?

A

High-level Disinfection

22
Q

Used in the disinfection of laboratory
benches and as part of detergent germicides, used for housekeeping purposes

A

intermediate-level disinfection

23
Q

Kills vegetative microorganisms
including:
→Mycobacterium tuberculosis, all
fungi, and inactivate viruses

A

intermediate-level disinfection

24
Q

Kills most vegetative bacteria M.
tuberculosis, some fungi and may inactivate some viruses
M. tuberculosis
Some fungi, and
May inactivate some viruses.

A

Low-level disinfection

25
Q

As a disinfectant, it is used for
relatively short periods of time

A

high-level disinfection

26
Q

Formulated on used for medical devices but not on environmental surfaces such as lab benches or floors

A

high-level disinfection

27
Q

used in this procedure in the US as hospital disinfectants or sanitizers.

A

low-level disinfection

28
Q

What is high-level disinfection used for?

A

used for medical devices

29
Q

what is low-level disinfection used for?

A

used in Hospitals as disinfectants or sanitizers

30
Q

what is intermediate-level disinfection used for?

A

Used in the disinfection of laboratory
benches and as part of detergent germicides, used for housekeeping purposes

31
Q

in the high-level disinfection, what is amount of time or relative time if it is being used as a disinfectant? what about sterilization?

A

disinfectant- relatively shorter time
Sterilization - longer time period 6-10 hours

32
Q

mention the types of microorganisms that a high-level disinfection is capable to kill?

A

vegetative microorganisms and inactivate viruses and not necessarily high number of bacterial spores

33
Q

mention the types of microorganisms that a hospital-grade disinfectants or sanitizers is capable to kill?

A

M. tuberculosis, Some fungi, andMay inactive some viruses. vegetative bacteria
