1

Examples of "sharps"

Knife Blades
Needles
Skin hooks
Scissors
Scalpels
Razors

2

Three priority goals of soiled item transportation

1. To prepare contaminated items
2. To transport soiled items without cross-contamination
3. To assure that all individuals remain safe

3

Highest amounts of contaminated items will be produced by:

Surgery

4

Less amounts of contaminated items will be produced by:

Labor & Delivery
Emergency Services
Endoscopy
Cardiac Cath Lab

5

Holding items until received by central services

Designated holding area with biohazard signage that is NOT accessible to visitors. Contains specific contaminated linen and trash receptacles

6

Instrument decontamination begins at

Point-of-use

7

Reasons for point-of-use preparations 1

Helps to prolong the life of instruments

8

Reasons for point-of-use preparations 2

Dried on soil and debris is harder to remove than moist soil

9

When should gross soil be removed from instruments

Immediately

10

Removing soil from gross instruments include:

Following manufacturers instructions
Keep soiled instruments moist
Remove disposable components
Separate reusable linen
Empty fluids container
Separate sharps from other instruments
Notify SPD about repairs needed

11

What are sharps

Knife blades and needles

12

What is gross soil

Tissue, body fat, blood, and other body substances

13

Why should contaminated items be contained before transport?

To minimize the spread of microorganisms, and to reduce the risk of cross-contamination

14

Prior to transport smaller instruments should be contained in....

Biohazard bags

15

Prior to transport larger items should be contained in....

Instrument carts with doors or covered in clear plastic

16

What does a SPD tech wear when transporting contaminated items?

A protective gown or coat over scrubs. Once items have been placed in the carts gloves should be removed and hands washed prior to moving the cart

17

Who creates the recommended transports for contaminated items to be transported

AAMI and OSHA

18

The removal of all visible and non visible soil

Cleaning

19

Removing or reducing contamination by infectious organisms or other harmful substances

Decontamination

20

The amount of water vapor in the atmosphere

Relative humidity

21

A term relating to infectious agents that present a risk or potential risk to human health

Biohazard

22

Why is the temperature low in decontamination

All the PPE makes the SPD agent hot, also a low temperature helps inhibit the growth of microorganisms

23

What 3 things are taken into consideration for decontamination lighting

Age of workers
Importance of speed and accuracy
Amount of light reflection in the work area

24

What emergency equipment should be available in decontamination

Eye wash station and hand washing station

25

When should work surfaces be cleaned

At the beginning and end of every shift

26

When should spills be cleaned up

Spot-cleaned immediately

27

When should floors be cleaned

Wet mopped and disinfected daily

28

When should biohazard be removed

At frequent intervals

29

What is standard precaution

Think every patient is infected with something

30

Staff Education and training should be...

Effective and ongoing

31

Effective cleaning agents 1

Are non abrasive
Low foaming
Free rinsing
Bio-gradable

32

Effective cleaning agents 2

Non toxic
Allow for rapid soil dispersion
Effective on all types of soil
Have a long shelf life
Cost effective
Can be monitored

33

A substance that reduces the surface tension of a liquid and allows the liquid to penetrate

Wetting agent

34

A measure of alkalinity or acidity

pH level
Chemicals that hold hard water minerals in solutions, and prevents soap from reacting with minerals

35

Chemicals that remove or inactivate hard water minerals

Sequestering agents

36

An example of a wetting agent

Water

37

What are the conditions of "pure" water

Must be free of particles, solids, microbes, and fever producing pyrogens

38

Why is the pH level of water important

It influences the effectiveness of enzymes and detergent cleaners

39

What is the pH of an acidic detergent

Low pH 0-6

40

What is the pH of an alkaline detergent

High pH 8-14

41

What color does acid turn litmus paper

Red

42

How does an enzyme detergent work

It breaks down or 'digests' large organic molecules to facilitate their removal

43

Why are enzymes specific in their actions?

A protein will not recognize fat molecules - it only recognizes molecules in their original state

44

How do protease enzyme perform?

Break down blood, mucous, feces, and albumin

45

How does lipase work

Breaks down fatty deposits such as bone marrow and adipose tissue

46

How does amylase work

Catalyzes (changes) starch

47

Enzymatic usually consist of detergents with a ....

neutral base

48

What should you consider when choosing an enzymatic solution?

Water temperature
Room temperature
Useful life and stability of product
Expiration date
Materials used to make the device to be cleaned
Approved by EPA

49

A surface-acting agent that lowers the surface tension of a liquid

Surfactant

50

What is often called "instrumentation milk"

Lubricants

51

What function does a lubricant perform

Inhibits rust
maintains the integrity of instrumentation

52

What technology challenges do SPD face

Crevices, joints, or surface pores
Clamps that cannot be opened to clean
Channels that are not freely accessible
Valves

53

What temperature should water be to prevent coagulation
