Answer 1

PROPER ASEPTIC TECHNIQUE

Question 2

Absence of microorganism that cause disease

Answer 2

ASEPSIS

Question 3

Process of removing as many microorganisms as possible from the hands and arms by mechanical washing and chemical antisepsis before participating in a surgical procedure

Answer 3

SURGICAL HAND ANTISEPSIS

Question 3

methods by which contamination with microorganisms is prevented

Answer 3

ASEPTIC TECHNIQUE

Question 4

What are the Principles of Aseptic Technique

Answer 4

1. Only sterile items are used within the sterile field
2. Sterile persons are gowned and gloved
3. Only top of a draped table us considered sterile
4. Sterile persons touch only sterile items or areas

Question 5

T/F: Despite the mechanical action and the chemical antimicrobial component of the scrub process, skin is never sterile

Answer 5

TRUE

Question 6

4 factors affecting the effectiveness of surgical hand antisepsis:

Answer 6

1. The preparation before cleansing
2. The choice of antiseptic solution
3. The cleansing method
4. The duration for hand cleansing

Question 7

What are the characteristics of a surgical scrub? (4)

Answer 7

1. Antimicrobial action
2. Persistent activity
3. Safety
4. Acceptance

Question 8

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 8

ANTIMICROBIAL ACTION

Question 8

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 8

ACCEPTANCE

Question 9

an agent offering persistent activity keeps the bacterial count low under the gloves.

Answer 9

PERSISTENT ACTIVITY

Question 10

Why is alcoholic chlorhexidine most used as cleansing solution

Answer 10

It has a greater residual of antimicrobial activity

Question 10

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 10

SAFETY

Question 11

Duration of a surgical scrub

Answer 11

3-5 mins

Question 11

is the destruction of all forms of microbial life

Answer 11

STERILIZATION

Question 12

It is an infection that occurs after surgery in the part of the body where the surgery took place.

Answer 12

SSI - SURGICAL SITE INFECTION

Question 12

What is a surgical site infection (SSI)?

Answer 12

It is an infection that occurs after surgery in the part of the body where the surgery took place.

Question 13

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

Answer 13

CLEANING

Question 14

What are the SSI Bundle intra-operative?

Answer 14

• Appropriate antibiotic dosing
• Environmental controls
• Maintain a clean environment
• Wear clean surgical attire
• Surgical skin prep and wound classification

• Minimize Traffic
• Adequate sterilization of instruments

Question 14

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

Answer 14

DISINFECTION

Question 15

Types of disinfection?

Answer 15

1. High level disinfection
2. Intermediate
3. Low-level

Question 16

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

Answer 16

HIGH-LEVEL DISINFECTION

Question 17

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

Answer 17

INTERMEDIATE DISINFECTION

Question 18

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 18

LOW-LEVEL DISINFECTION

Question 19

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

Answer 19

1. Critical
2. Semicritical
3. Noncritical

Question 20

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

Answer 20

CRITICAL ITEMS

Question 21

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

Answer 21

SEMICIRITCAL ITEMS

Question 22

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

Answer 22

NONCRITICAL ITEMS

Question 23

This is the most inexpensive and effective method for sterilization.

Answer 23

STEAM STERILIZATION

Question 24

It is a more complex and expensive process than steam sterilization

Answer 24

ETHYLENE OXIDE GAS STERILIZATION
