24
Q

BSL __ laboratories handle agents that have no known potential for infecting healthy people

A

Biosafety level 1

25
Q

BSL __ laboratories are those laboratories that work with microorganisms associated with human diseases that are rarely serious and for which preventive or therapeutic interventions are often available.

A

Biosafety Level 2

26
Q

BSL __ is recommended for materials that may contain viruses not normally encountered in a clinical laboratory and for the cultivation of mycobacteria. Working with mycobacteria requires the use of N95 HEPA filter respirators.

A

Biosafety Level 3

27
Q

BSL __ is required for work with dangerous and exotic agents that pose a high risk of aerosol-transmitted laboratory infections and life-threatening disease for which effective treatments are limited

A

Biosafety level 4

28
Q

Risk factor: pathogens on hands of medical personnel, invasive procedures, antibiotic use

A

Iatrogenic

29
Q

Risk factor: contaminated aircon systems, staffing, physical layout of facility

A

Organizational

30
Q

Risk factor: severity of illness, length of stay

A

Patient risk factor

31
Q

Source or a situation that may cause harm or injury

A

Hazard

32
Q

Likelihood or probability fora hazard to cause harm

A

Risk

33
Q

This guideline recommends wearing gloves when collecting or handling blood and body fluids contaminated with blood and wearing face shields when there is a danger of blood splashing on mucous membranes and when disposing of all needles
and sharp objects in puncture-resistant containers

A

Universal precautions

34
Q

This guideline are not limited to bloodborne pathogens; they consider all body fluids and moist body substances to be potentially infectious

A

Body substance isolation

35
Q

According to this guidelines, personnel should wear gloves at all times when encountering moist body substances.

A

Body substance isolation

36
Q

This guideline do not recommend handwashing following removal of gloves unless visual contamination is present

A

Body substance isolation

37
Q

This guideline assume that everyone is potentially infected or colonized with an organism that can betransmitted in the healthcare setting

A

Standard precaution

38
Q

It combines the guidelines of universal precautions and body substance isolation

A

Standard precautions

39
Q

What is the most effective method in the hierarchy of controls?

A

Elimination

40
Q

What is the least effective method in the hierarchy of controls?

A

Personal protective equipment (PPE)

41
Q

Hierarchy of controls from most to least effective

A

Elimination, substitution, engineering controls, administrative controls, PPE

42
