Lecture #4 Infection Control Program

Question 1

differentiate between Universal precautions and Standard precautions

Answer 1

Universal - 1980’s, protect against Bloodborne diseases

Standard - 1990’s, protect against blood and all other bodily fluids (except sweat)

Question 2

Goal of an infection control program

Answer 2

1. Eliminate cross contamination and potential exposure to pathogenic microorganisms for patients and DHCW’s

• Infection control is a result of exposure control
• Decrease exposure/decrease infection

Question 3

6 parts of implementation of an infection control program

Answer 3

1. Standard precautions
2. Host immunity and Immunizations
3. Patient health history
4. Extraoral and Intraoral examinations
5. Personal Hygiene/Appearance
6. Hand care

Question 4

5 more parts to the implementation of an infection control program

Answer 4

1. PPE
2. Barrier Protection
3. High velocity evacuation
4. Reduce microbial load
5. Sterilization of instruments

Question 5

3 parts of Spauldings Classifications

Answer 5

1. Critical
2. Semicritical
3. Noncritical

Question 6

Define the Critical, Semicritical and Noncritical classifcations of Spaulding

Answer 6

Critical - Direct Contact/invasive
Semicritical - Direct or indirect penetration of mucous membrane not anticipated
Noncritical - Direct or Indirect contact

Question 7

What are the levels of decontamination for each of spaulding’s classifications

Answer 7

Critical - Sterilization
Semicritical-Sterilization or intermediate level disinfection
Noncritical - Disinfection, Sanitization, Barriers

Question 8

Method of Decontamination for each of spauldings classifications

Answer 8

Critical - Heat sterilization preferred
Semicritical - Heat sterilization or intermediate level disinfectant
Noncritical - Surface cleaner or intermediate level disinfectant

Question 9

Define sterilization

Answer 9

results in the destruction of all forms of microbial life including bacteria, viruses, spores, and fungi

Question 10

Define Intermediate level disinfection

Answer 10

Destroys vegetative bacteria, mycobacterium, fungi and enveloped and non-enveloped viruses
- Does not destroy bacterial spores

Question 11

Define Low level disinfection/sanitation

Answer 11

Kill most vegetative bacteria and some fungi as well as enveloped viruses
- Does not kill mycobacteria or bacterial spores

Question 12

What is a DHCW’s greatest risk?

Answer 12

Exposure to blood borne pathogens
