- Within 30 days of employment at no cost to the employee
- Within 10 working days of initial assignment at no cost (Correct answer)
- Within 60 days after completing orientation
- Annually at a subsidized cost to the employee

Question 2: Which hand hygiene method is most effective against Clostridium difficile spores?
- Alcohol-based hand rub for 20 seconds
- Soap and water handwashing for 20 seconds (Correct answer)
- Chlorhexidine gluconate rub

Question 4: The purpose of a laminar airflow workbench (LAFW) in IV compounding is to:
- Protect the compounder from hazardous drugs
- Provide a sterile environment by directing HEPA-filtered air over the work surface (Correct answer)
- Remove volatile organic compounds from the air
- Maintain negative pressure to contain contaminants
Correct answer: Provide a sterile environment by directing HEPA-filtered air over the work surface
A LAFW provides a Class 100 (ISO 5) sterile work environment by directing HEPA-filtered unidirectional airflow across the work surface.
Question 5: Which of the following is classified as a Category II hazardous waste under RCRA regulations?

- 10,000
- 100,000
- 3,520 (Correct answer)
- 352,000
Correct answer: 3,520
ISO Class 5 permits a maximum of 3,520 particles ≥0.5 µm per cubic meter, equivalent to the former Class 100 designation.
