When performing aseptic manipulations inside a horizontal laminar airflow workbench (LAFW), where should critical sites be positioned relative to the HEPA filter?
Answer: Directly in the path of unobstructed HEPA-filtered airflow
Critical sites must be placed in the direct, unobstructed path of HEPA-filtered air to prevent contamination from non-sterile room air.
A technician notices their sterile gloves have small holes after removing them post-compounding. What is the most appropriate immediate action?
Answer: Document the incident and discard the batch compounded
Compromised gloves mean the integrity of the sterile field cannot be guaranteed, so the affected batch must be discarded and the incident documented.
What is the primary purpose of the 'no-touch' technique in aseptic compounding?
Answer: To prevent direct contact with critical sites such as needles, vial stoppers, and ports
The no-touch technique protects critical sites (needles, vial stoppers, ports, syringe tips) from direct contact that could introduce microorganisms.
Which action correctly demonstrates proper gowning order when entering a cleanroom?
Answer: Hand hygiene → shoe covers → hair cover → gown → mask → gloves
USP specifies hand hygiene first, followed by shoe covers, hair/beard covers, gown, mask/eye protection, and finally sterile gloves as the last item donned.
How far from the outer edge of the LAFW work surface should a technician avoid placing materials, and why?
Answer: 3 inches, because airflow is turbulent in that zone and non-sterile room air may enter
The first 3 inches of the LAFW work surface (the 'dead zone') may be exposed to room air turbulence and should not contain critical items.
A compounder is working in a BSC (biological safety cabinet) and accidentally places their arm over an open vial. What contamination risk does this create?
Answer: Disruption of vertical airflow, allowing non-sterile air or particles to fall into the vial
In a BSC, airflow moves vertically downward; placing an arm over an open critical site blocks that sterile downflow and creates a contamination pathway.
Which of the following best describes the concept of 'first air' in laminar airflow workbenches?
Answer: The HEPA-filtered air that has not yet contacted any surface or object inside the hood
First air is the unobstructed HEPA-filtered air flowing directly from the filter before it contacts any object; critical sites must always be in the path of first air.
