Aseptic Technique and Garbing Flashcards

What is the primary purpose of performing hand hygiene before entering the buffer area?

Answer: To reduce bioburden on the skin

Hand hygiene before entering the buffer area reduces the bioburden (microbial load) on the skin, which is a critical first step in preventing contamination of compounded sterile preparations.

In the garbing sequence, which item should be donned AFTER shoe covers but BEFORE the sterile gown?

Answer: Face mask and hair cover

The correct garbing order requires putting on a face mask and hair cover after shoe covers and before the sterile gown to minimize particle shedding onto the gown.

How frequently should sterile gloves be sanitized with 70% IPA during continuous compounding operations?

Answer: Before each new CSP and frequently during compounding

Sterile gloves should be sanitized with 70% IPA before initiating each new CSP and frequently throughout the compounding process to maintain aseptic conditions.

What is the correct action if a technician gown sleeve touches the outer edge of the laminar airflow workbench?

Answer: Sanitize the sleeve with 70% IPA and continue

If a gown sleeve contacts the outer edge of the LAFW, the area should be sanitized with 70% IPA. Complete re-garbing is not required for incidental contact if the gloves and critical site were not compromised.

Which of the following is considered a critical site during IV admixture preparation?

Answer: The needle hub prior to attachment

The needle hub is a critical site because it comes in direct contact with the sterile fluid pathway. Any contamination here can directly enter the CSP.

What is the purpose of the ante-area in sterile compounding facility design?

Answer: To provide a transition zone for garbing and hand hygiene before entering the buffer area

The ante-area serves as an ISO Class 8 transition zone where personnel perform hand hygiene, garbing, and staging of components before entering the cleaner buffer area.
