Q1What is the required ISO classification inside a primary engineering control such as a laminar airflow workbench during sterile compounding?
Show answer
✓ Correct answer: ISO Class 5
ISO Class 5 is the required air quality classification for the direct compounding environment inside primary engineering controls to minimize particulate contamination during sterile preparation.
Q2Which type of primary engineering control should be used when compounding hazardous sterile preparations?
Show answer
✓ Correct answer: Biological safety cabinet
A biological safety cabinet or compounding aseptic containment isolator provides both product protection and personnel protection through negative pressure and HEPA-filtered exhaust, making them appropriate for hazardous drug compounding.
Q3What is the correct pressure differential relationship between a buffer room and an anteroom when compounding non-hazardous sterile preparations?
Show answer
✓ Correct answer: Buffer room positive to anteroom
The buffer room must maintain positive pressure relative to the anteroom to prevent less clean air from entering the cleanest compounding area, protecting the sterile compounding environment.
Q4Which component is essential for maintaining ISO Class 5 air quality in a laminar airflow workbench?
Show answer
✓ Correct answer: HEPA filter
HEPA (High Efficiency Particulate Air) filters remove 99.97% of particles 0.3 microns or larger, creating the ISO Class 5 environment required for sterile compounding.
Q5What is the minimum ISO classification required for an anteroom in a facility performing sterile compounding?
Show answer
✓ Correct answer: ISO Class 8
ISO Class 8 is the minimum classification for anterooms, providing a transitional environment between unclassified areas and the ISO Class 7 buffer room.
Q6Which type of environmental monitoring detects living microorganisms in the compounding area?
Show answer
✓ Correct answer: Viable air sampling
Viable air sampling uses collection media to capture and culture living microorganisms from the air, allowing detection and quantification of microbial contamination.
