16
Q

This is a major component of Standard Precautions

A

PPE

17
Q

What does PPE protect

A

the skin and mucous membranes from exposure to infectious materials in spray or spatter

18
Q

When should PPE be removed

A

when leaving the treatment areas

19
Q

Why is hand hygiene important (3 things)

A

hands are the most common mode of pathogen transmission
reduce the spread of antimicrobial resistance
prevent health-care associated infections

20
Q

What are four methods of proper hand hygiene

A

hand washing
antiseptic hand washing
alcohol-based handrub
surgical anti-sepsis

21
Q

When are three time when hands need to be cleaned

A

visibly dirty
after touching contaminated objects with bare hands
before and after patient treatment (before glove placement and after glove removal)

22
Q

Rank these in order of good, better, and best;
antimicrobial soap
plain soap
alcohol-based handrub

A

plain soap < antimicrobial soap < alcohol based hand-rub

23
Q

What are the critical instruments to sterilize and disinfect

A

those that penetrate mucous membranes or contact bone, the bloodstream, or other normally sterile tissues (of the mouth)
surgical instruments, scalpels, periodontal scalers, surgical dental burs

24
Q

How should you properly sterilize/disinfect critical instruments

A

heat sterilize between use or use sterile single-use, disposable devices

25
Q

What are the semi-critical instruments

A

Those that contact mucous membranes but do not penetrate soft tissue
mouth mirrors, amalgam condensers, mental handpieces

26
Q

How should you properly sterilize/disinfect semi-critical instruments

A

heat sterilize or high-level disinfect

27
Q

What are the non-critical instruments and devices

A

those that contact intact skin

X-ray heads, face bows, pulse oximeter, BP cuff

28
Q

How should you properly sterilize/disinfect non-critical instruments

A

clean and disinfect using a low to intermediate level disinfectant

29
Q

What are three characteristics of single-use (disposable) devices

A

intended for use on one patient during a single procedure
usually not heat-tolerant
cannot be reliably cleaned
syringes, prophylaxis cups, plastic orthodontic brackets, matrix bands, wedges, polishing discs/points

30
Q

What are the two categories of environmental surfaces

A

clinical contact surfaces

housekeeping surfaces

31
Q

This environmental surface has a high potential for direct contamination from spray or spatter or by contact with DHCPs gloved hand

A

clinical contact surface

32
Q

This environmental surface does not come into contact with patients or devices; limited risk of disease transmission

A

housekeeping surfaces

33
Q

What are 4 general cleaning recommendations

A
  1. Use barrier precautions (e.g., heavy-duty utility gloves, masks, protective eyewear) when cleaning and disinfecting environmental surfaces
  2. Physical removal of microorganisms by cleaning is as important as the disinfection process
  3. Follow manufacturer’s instructions for proper use of EPA- registered hospital disinfectants
  4. Do not use sterilant/high-level disinfectants on environmental surfaces
34
Q

What is the proper protocol for flushing the air/water lines for the high speed and air/water syringe

A

Flush lines 2-3 minutes at beginning of day
20-30 seconds, BEFORE & AFTER patient treatment
After attaching handpieces, insert bur & run High Speed for 20-30 seconds before treatment

35
Q

What is the proper protocol for flushing the evacuation lines; saliva ejector and HVE

A

Remove the disposable tips and run several cups of warm water through lines after patient treatment

36
Q

What are the four types of waste

A

General waste
Contaminated waste Hazardous waste
Infectious waste

37
Q

What are the 5 regulatory/advisory agencies

A
  1. OSHA (Occupational Safety & Health Administration)
  2. EPA (Environmental Protection Agency)
  3. OSDB (Ohio State Dental Board)
  4. FDA (Food and Drug Administration)
  5. CDC (Centers for Disease Control and Prevention)
38
Q

What are the four steps in returning used instruments to dispensary

A
  1. Wear Gloves and Gown
  2. Wrap cassettes in blue sterilization paper
  3. Be sure instruments are in proper order
