(Lecture) Control of Microorganism

Question 1

A type of precaution wherein blood and all body fluids, including secretions and excretions except sweat, regardless of whether visible blood is present, are considered infectious

Answer 1

Universal or Standard Precautions

Question 2

Types of Transmission-Based Precautions

Answer 2

1. Contact Precautions
2. Droplet Precautions
3. Airborne Precautions

Question 3

Used to stop the spread of infectious agents that may be transmitted through direct or indirect contact with the patient or with the patient’s environment.

Answer 3

Contact Precautions

Question 4

Used to stop the spread of infectious agents that can be transmitted by close respiratory contact or by exposure of mucous membranes to respiratory secretions.

Answer 4

Droplet Precautions

Question 5

Used for infectious agents such as Mycobacterium tuberculosis, varicella virus, and rubeola virus that can remain airborne and infectious over long distances.

Answer 5

Airborne Precautions

Question 6

A process used to recognize the hazardous characteristics of infectious agents that may be encountered in the clinical microbiology laboratory.

Answer 6

Biological Risk Assessment

Question 7

Identify the Risk Group:

A microorganism that is unlikely to cause human or animal disease

Answer 7

Risk Group 1 (No or Low Individual and Community Risk)

Question 8

Identify the Risk Group:

A pathogen that can cause human or animal disease but is unlikely to be a serious hazard to laboratory workers, the community, livestock, or the environment. Laboratory exposures may cause serious infection, but effective treatment and preventive measures are available, and the risk of spread of infection is limited

Answer 8

Risk Group 2 (Moderate Individual Risk, Low Community Risk)

Question 9

Identify the Risk Group:

A pathogen that usually causes serious human or animal disease but does not ordinarily spread from one infected individual to another. Effective treatment and preventive measures are available

Answer 9

Risk Group 3 (High Individual Risk, Low Community Risk)

Question 10

Identify the Risk Group:

A pathogen that usually causes serious human or animal disease and that can be readily transmitted from one individual to another, directly or indirectly. Effective treatment and preventive measures are not usually available

Answer 10

Risk Group 4 (High Individual and Community Risk)

Question 11

A type of containment barrier that protects the worker from the aerosolized transmission of organisms.

Answer 11

Biological Safety Cabinets

Question 12

Biological Safety Cabinets Types:

Answer 12

Class I
Class II
Class III

Question 13

• Biological safety hood used an exhaust fan to move air inward through the open front.
• The air is circulated within the safety hood, passing through a high-efficiency particulate air (HEPA) filter before reaching the environment outside the hood.

Answer 13

Class I

Question 14

• biological safety hood is the most common in microbiology laboratories.
• Air is pulled inward and downward by a blower and passed up through the airflow plenum where it passes through a HEPA filter before reaching the work surface.
• A percentage of the remaining air is HEPA filtered before reaching the environment.

Answer 14

Class II

Question 15

• Biological safety hood is a self-contained ventilated system for highly infectious microorganisms or materials and provides the highest level of personal protection.
• The closed front contains attached gloves for manipulations on the work surface.

Answer 15

Class III
