CSPT Aseptic Technique and Garbing 4

Question 1

When performing aseptic manipulations inside a horizontal laminar airflow workbench (LAFW), where should critical sites be positioned relative to the HEPA filter?

Accepted Answer

Directly in the path of unobstructed HEPA-filtered airflow

Answer

Critical sites must be placed in the direct, unobstructed path of HEPA-filtered air to prevent contamination from non-sterile room air.

Question 2

A technician notices their sterile gloves have small holes after removing them post-compounding. What is the most appropriate immediate action?

Accepted Answer

Document the incident and discard the batch compounded

Answer

Compromised gloves mean the integrity of the sterile field cannot be guaranteed, so the affected batch must be discarded and the incident documented.

Question 3

What is the primary purpose of the 'no-touch' technique in aseptic compounding?

Accepted Answer

To prevent direct contact with critical sites such as needles, vial stoppers, and ports

Answer

The no-touch technique protects critical sites (needles, vial stoppers, ports, syringe tips) from direct contact that could introduce microorganisms.

Question 4

Which action correctly demonstrates proper gowning order when entering a cleanroom?

Accepted Answer

Hand hygiene → shoe covers → hair cover → gown → mask → gloves

Answer

USP <797> specifies hand hygiene first, followed by shoe covers, hair/beard covers, gown, mask/eye protection, and finally sterile gloves as the last item donned.

Question 5

How far from the outer edge of the LAFW work surface should a technician avoid placing materials, and why?

Accepted Answer

3 inches, because airflow is turbulent in that zone and non-sterile room air may enter

Answer

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.
