FINALS QUIZ

Question 1

Proper ____ is one of the most fundamental and essential principles of infection control in the clinical and Surgical setting.

Answer 1

aseptic techniques

Question 2

Aseptic Techniques are those which:

Answer 2

Remove/reduce or kill microorganisms from hands and abjects
Employ sterile instruments
Reduce patient risk of exposure to microorganisms that cannot be removed

Question 3

Immediately before and during surgical procedures to reduce post-operative infection:
Hand washing
Surgical Attire
Surgical scrub, sterile gowning & gloving
Patients surgical skin prep
Using surgical barriers (surgical drapes and PPE)
Using safe operative technique

Answer 3

Aseptic Technique

Question 4

Absence of microorganism that cause disease
Freedom from infection

Answer 4

Asepsis

Question 5

methods by which contamination with microorganisms is prevented

Answer 5

Aseptic Technique

Question 6

Only ___ are used within the sterile field

Answer 6

sterile items

Question 7

Destruction of the integrity of microbial barriers results in ___

Answer 7

contamination

Question 8

4 factors affecting the effectiveness of surgical hand antisepsis:

Answer 8

The preparation before cleansing
The choice of antiseptic solution
The cleansing method
The duration for hand cleansing

Question 9

• an ideal agent would have a broad spectrum of antimicrobial activity against pathogenic organisms. This agent would have to work rapidly. An agent that does not work rapidly may not provide adequate bacterial reduction before being rinsed off.

Answer 9

Antimicrobial Action

Question 10

• an agent offering persistent activity keeps the bacterial count low under the gloves, It is not unusual for a surgery to last in excess of two hours. Studies have shown the rate of glove failures (non-visible holes) increases with the duration of surgery. In addition, studies show bacteria grow faster under gloves than ungloved hands.

Answer 10

Persistent Activity

Question 11

• the ideal agent would be non-irritating and non-sensitizing. It must have no appreciable ocular or ototoxicity, be safe for use on the body, and not be damaging to the skin or environment.

Answer 11

Safety

Question 12

• probably most important to achieving compliance in using a new product is its acceptance by the healthcare worker. A product that has ideal antimicrobial action and an excellent safety profile is of little value to good infection control if the user population fails to support its use. Although each is important in its own right, all four characteristics should be present for a complete package.

Answer 12

Acceptance

Question 13

All surgical scrubs are ___ minutes in length
All are performed using a surgical scrub brush and an antimicrobial sor solution

Answer 13

3-5

Question 14

the physical removal of organic material or soil from objects, is usually done by using water with or without detergents.

Answer 14

Cleaning

Question 15

is the destruction of all forms of microbial life; it is carried out in the hospital with steam under pressure, liquid or gaseous chemicals, or dry heat.

Answer 15

Sterilization

Question 16

, defined as the intermediate measures between physical cleaning and sterilization, is carried out with pasteurization or chemical germicides.

Answer 16

Disinfection

Question 17

The level of disinfection achieved depends on several factors:

Answer 17

contact time
temperature
type and concentration of the active ingredients of the chemical germicide
the nature of microbial contamination.

Question 18

: can be expected to destroy all microorganisms, with the exception of large numbers of bacterial spores.

Answer 18

High-level disinfection

Question 19

: inactivates Mycobacterium tuberculosis, vegetative bacteria, most viruses, and most fungi; does not necessarily kill bacterial spores.

Answer 19

Intermediate disinfection

Question 20

: can kill most bacteria, some viruses, and some fungi; cannot be relied on to kill resistant microorganisms such as tubercle bacilli or bacterial spores.

Answer 20

Low-level disinfection

Question 21

Medical devices, equipment, and surgical materials are divided into three general categories based on the potential risk of infection involved in their use:

Answer 21

critical items
semicritical items
noncritical item

Question 22

are instruments or objects that are introduced directly into the bloodstream or into other normally sterile areas of the body.

Answer 22

Critical items

Question 23

These items come in contact with intact mucous membranes, but they do not ordinarily penetrate body surfaces.

Answer 23

Semicritical items

Question 24

are those that either do not ordinarily touch the patient or touch only intact skin.

Answer 24

Noncritical items

Question 25

Items ____ before processing, because organic material (e.g blood and proteins) may contain high concentrations of microorganisms.

Answer 25

must be thoroughly cleaned

Question 26

is the most inexpensive and an effective method for sterilization.

Answer 26

Steam sterilization

Question 27

Role of CSSD

Answer 27

Rinsing
Cleaning
Drying
Inspection and assembly
Packaging
Labeling
Sterilization
Storage
