A healthcare worker is treating a patient with active pulmonary tuberculosis. In addition to an N95 respirator, which room type is required?
Answer: Negative-pressure airborne infection isolation room
Active pulmonary TB requires airborne precautions including placement in a negative-pressure AIIR to prevent spread of M. tuberculosis aerosols to other areas.
The 'Swiss Cheese Model' of accident causation, developed by James Reason, describes which safety concept?
Answer: Multiple independent barriers each with weaknesses that, when aligned, allow accidents to occur
Reason's Swiss Cheese Model illustrates that accidents occur when holes (weaknesses) in multiple defensive layers align simultaneously, creating an uninterrupted path to harm.
Which chemical sterilization method is commonly used for heat-sensitive medical devices and operates at low temperatures with a highly penetrating agent?
Answer: Ethylene oxide (EtO) gas sterilization
Ethylene oxide gas sterilization is effective at low temperatures (37–63°C) and penetrates packaging and device lumens, making it suitable for heat-sensitive instruments.
Under OSHA's Recording and Reporting Occupational Injuries and Illnesses standard (29 CFR 1904), what is the employer's deadline to report a work-related hospitalization of one or more employees?
Answer: Within 24 hours
Employers must report in-patient hospitalizations of one or more employees to OSHA within 24 hours of learning about the event.
Which of the following hand hygiene products is NOT effective against Clostridioides difficile (C. diff) spores?
Answer: Alcohol-based hand rub (ABHR)
Alcohol-based hand rubs do not kill C. diff spores; soap-and-water handwashing is required because the physical scrubbing mechanically removes spores from hands.
An employer wishes to use an exempt quantity of a hazardous chemical that does not require an SDS on file. Under the OSHA HazCom standard, what is the threshold below which a chemical is considered a 'consumer product' and may be exempt?
Answer: Used in quantities and frequencies that do not exceed ordinary consumer use
Under HazCom, consumer products used in the same manner and frequency as a typical consumer (not in greater duration or quantity) may be exempt from SDS and labeling requirements.
In OSHA's General Duty Clause (Section 5(a)(1) of the OSH Act), employers are required to provide a workplace free from recognized hazards that are causing or are likely to cause which outcome?

The General Duty Clause requires employers to address recognized hazards that are causing or are likely to cause death or serious physical harm to employees.
