Question 9

In 1972, Dr. Earl Spaulding proposed a system for classifying liquid chemical germicides and inanimate surfaces.

Answer 9

Spaulding classification

Question 10

when was spaulding classification proposed? and who proposed it?

Answer 10

1972, Dr. Earl Spaulding

Question 11

from the Spaulding classification under the inanimate surface categories, these are Instruments or devices that are exposed to normally sterile areas of the body require sterilization.

Answer 11

critical

Question 12

what are the inanimate surface categories in Spaulding classification?

Answer 12

Critical, semi-critical, non-critical

Question 13

from the Spaulding classification under the inanimate surface categories, these are Instruments or devices that touch skin or come into contact with person only indirectly

Answer 13

non-critical

Question 14

from the Spaulding classification under the inanimate surface categories, these are Instruments or devices that touch mucous membranes may either sterilized or disinfected.

Answer 14

semi-critical

Question 15

inanimate surfaces that are considered critical are requires what process of cleaning? how about semi-critical? non-critical?

Answer 15

Critical- Sterilization
semi-critical - sterilization or disinfection
Non-critical - intermediate level disinfection, sanitized with low level disinfectant or soap and water

Question 16

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

Answer 16

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

Question 17

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

Answer 17

environmental surfaces
