30

Question 20

____ are enclosures which provide HEPA-filtered ISO class 5 unidirectional air which allows for the passage of materials through defined openings that are generally not to be opened during operations.

Answer 20

Restricted Access Barrier Systems

These are typically located in a segregated compounding area (SCA) or a buffer room.

Question 21

____ are a type of restricted-access barrier system which uses HEPA filtration to provide ISO class 5 unidirectional air flow for the purpose of compounding sterile non-hazardous drugs.

Answer 21

Compounding Aseptic Isolator.

Question 22

Are sterile gloves required when working in a restricted access barrier system such as a compounding aseptic isolator?

Answer 22

Yes. Both on the sleeve and over the sleeve.

Question 23

_____ is an SEC without the controls of a cleanroom. This is an area dedicated to sterile compounding which is exposed to room air as opposed to ISO-class air.

Answer 23

Segregated Compounding Area

Question 24

May a segregated compounding area be in a hallway?

Answer 24

No, it must be in a separate room or at least have a visible perimeter to establish boundary.

Question 25

May you don gloves before entering the sterile compounding room or other classified area?

Answer 25

No.

Question 26

May hand sanitizer be used in replacement of soap when washing hands for sterile compounding?

Answer 26

No

Question 27

____ should be applied to gloves regularly throughout compounding and whenever non-sterile surfaces are touched.

Answer 27

70% isopropyl alcohol.

Question 28

May gowns be re-used within the same shift?

Answer 28

Yes only if gown is maintained in a classified area/inside perimeter of a segregated compounding area.

Question 29

General Garbing Procedure for Non-hazardous medication preparation.

Answer 29

1) Remove all jewelry, jackets, vests, etc.
2) Don shoe covers, stepping over line of demarcations
3) Don face mask, hand/hair covers
4) Wash hands (30 seconds)
5) Don Gown
6) Enter Clean room
7) Hand Cleansing with alcohol-based product
8) Don Sterile Gloves
9) Routinely disinfect gloves with sterile 70% isopropyl alcohol.

Question 30

How should a horizontal LAFW be cleaned?

Answer 30

1) Top using side-to-side motion from inside out.
2) Hanging pole using gripping motion
3) Sides, using top-to-bottom motion from inside out.
4) Bottom, using side-to-side motion from inside out.

This should be done using a 70% isopropyl alcohol wipe. NEVER SPRAY CLEANSER INSIDE THE PEC.

Question 31

How should you clean the diffuser if needed?

Answer 31

Should be done first if it is to be done. This is facility dependent and considered controversial however.

Question 32
