Q

What is the importance of removing bioburden prior to disinfection

A

the organic material in saliva and blood can inactivate chemicals in the disinfectant and the microorganism can insulate themselves in it

16
Q

transfer surfaces

A

surfaces that touch something that has been contaminated (like a counter top)

17
Q

Housekeeping surfaces

A

surfaces around the unit that may be contaminated but are not directly contaminated, may has remnant of aerosols/ spatter

18
Q

Describe the spray-wipe-spray method

A

spray the cleaner then wipe it (preclean), then spray the disinfectant again and let sit for the indicated amount of time

19
Q

What is the purpose of precleaning

A

precleaning will break down the extra layer of bioburden so the disinfectant will be more effective

20
Q

bioburden

A

saliva or blood

21
Q

biofilm

A

a mass of microorganisms attached to a surface exposed to moisture ; commonly found in waterlines if not maintained properly

22
Q

What is the rationale for maintaining waterlines

A

its essential for maintaining high quality patient care

23
Q

waste management

A

the handling of waste in a facility

24
Q

what is the EPA’s role in waste management

A

-governs the disposal of infectious waste
-workplace exposure levels for chemicals, heat and radiation

25
Q

What is OSHAs role

A

they make regulations concerning blood-borne pathogens, hazardous material and safe use of chemicals

26
Q

What are the 2 main types of waste

A

regulated and nonregulated

27
Q

what is regulated waste

A

waste that needs careful disposal as it contains blood or OPIM

28
Q

Sharps conatiners

A

-must be puncture resistant
-must be red and labeled
-must be leak proof
-must have a fill line (once this is reached the sharpers must be disposed of within 7 days)

29
Q

Biohazard containers

A

-must be covered
-must be red and labeled
-must be readable from a distance of 5 ft

30
Q

What is nonregulated waste

A

waste that is not shown to have a disease-producing potential; can be disposed on with non-medical garbage

31
Q

hazardous waste

A

waste posing a risk to humans or environment

32
Q

toxic waste

A

waste capable of having a poisonous effect

33
Q

What is SDS

A

-Safety Data Sheet

-provides info on a specific product (the handling toxicity, health effects, first aid, reactivity, storage, spill/leak procedures, protective equipment)

-these are required for each chemical within a facility

34
Q

Who regulates SDS

A

OSHA

35
Q

what are “engineering controls”

A

devices that reduce the risk of exposure to potentially infectious material

36
Q

OSHA Hazard Communication Standard

A

someone in the office is required yearly to go over…

-the sds
-explanation of hazardous chemicals (handling, labeling, how they are used )
-exit routes in an emergency

37
Q

how long does the office keep the Communication standard records and what should it include

A

-records should be kept for 3 years
-should includes who did the review, who attended and the date

38
Q

What is the purpose of the office safety program

A

to keep the office updated and in the most recent findings

39
Q

all employees must know…

A
  1. OSHA regulations (BB pathogens, hazardous material and safe use of chemicals)

2.EPA standards (workplace exposure levels)

3.State requirements concerning sterilization, disinfection, and med waste management

4.CDC guidelines

5.ADHA guidelines

  1. Post Exposure Protocol
