Chapter 18 19 20 21 Test

Front 1

The dental assistant must acquire

Back 1

A foundation in microbiology to understand the ways to prevent the transmission of disease in the dental office

Front 2

Pathogens are

Back 2

Disease producing microorganisms

Front 3

The five major groups of microorganisms are:

Back 3

Bacteria, algae, protozoa, fungi, and viruses

Front 4

Virulence means

Back 4

The degree of pathogenicity, or the strength of the organism in its ability to cause disease

Front 5

Acute infections are

Back 5

Of short duration

Front 6

Curtain pathogens, referred to as blood-borne,

Back 6

Are carried in the blood and body fluids of infected individuals and can be transmitted to others

Front 7

Immunity

Back 7

Allows the body to resist disease and prevents foreign bodies from causing infection

Front 8

You must wash your hands before

Back 8

You put on gloves and immediately after you remove gloves

Front 9

Alcohol-based hand rubs:

Back 9

These products are more effective than plain soaps, or even an antimicrobial hand wash, at reducing microbial flora

Front 10

The BBP standard prohibits

Back 10

An employee from taking protective clothing home to be laundered: laundered in office of laundry service

Front 11

The safest approach for avoiding contamination is

Back 11

To assume that of the surface has had contact with saliva, blood, or other potentially infectious material, live microorganisms are present

Front 12

Clinical contact surfaces can be directly contaminated by

Back 12

Direct spray or splatter generated during dental procedures, or by contact with the dental professional's gloved hands * these must be rigorously cleaned and discontaminated*

Front 13

Two methods that may be used to deal with surface contamination are

Back 13

To prevent the surface from becoming contaminated with the use of a surface barrier, and to preclean and disinfect the surface between patients

Front 14

Between patients,

Back 14

While you are still gloved, you should remove and discard contaminated barriers.

Front 15

Surfaces typically protected with barriers:

Back 15

NOT floors and walls.

Front 16

The Occupational Safety and Health Administration (OSHA) Blood-Borne pathogens Standard requires

Back 16

That contaminated work surfaces be disinfected between patient visits

Front 17

The Environment Protection Agency (EPA)

Back 17

Registers and regulates disinfectants and chemical sterilant according to chemical classifications

Front 18

You must always use personal protective equipment (PPE), including

Back 18

Utility gloves, mask, eyewear, protective clothing, when processing instruments

Front 19

Exposure can occur through percutaneous injury or by contact

Back 19

with the mucous membranes of the eyes, nose, or mouth

Front 20

The "ideal" instrument- processing area

Back 20

Should be dedicated only to instrument processing

Front 21

Before sterilization,

Back 21

The instruments should be wrapped or packaged to protect them from becoming contaminated after sterilization. An additional advantage to package instruments is that they can be grouped into special setups

Front 22

Results of sterilization errors:

Back 22

Improper packaging, improper loading of sterilizer, improper timing.

Front 23

Three forms of sterilization monitoring are used:

Back 23

Physical, chemical, and biologic

Front 24

In many areas,

Back 24

Glytaraldwhyde is considered a hazardous material, requires special disosal methods, and may not be dumped down the sink.
