IAHCSMM Packaging and Sterile Barrier Systems 3

Question 1

Which sterilization method requires special packaging materials that are permeable to the sterilant gas?

Accepted Answer

Ethylene oxide (EO) sterilization

Answer

EO sterilization requires packaging permeable to ethylene oxide gas so the sterilant can penetrate and contact all surfaces of the device.

Question 2

When wrapping instruments using the square (envelope) fold technique, how many wraps are typically used to achieve an aseptic presentation?

Accepted Answer

Two wraps (sequential or simultaneous)

Answer

The sequential double-wrap method creates two separate sterile barriers and allows aseptic delivery to the sterile field.

Question 3

A technician notices that a peel pouch has a 'channel seal' defect after sterilization. What is the correct action?

Accepted Answer

Reject the pack, reprocess the item, and repackage it

Answer

A channel seal (incomplete seal) compromises the sterile barrier; the item must be rejected, reprocessed, and repackaged in new packaging.

Question 4

What is the primary reason instruments should not be packaged while still wet after washing?

Accepted Answer

Moisture can prevent sterilant penetration and support microbial growth

Answer

Residual moisture can create wet packs during steam sterilization and may support microbial growth, compromising sterility.

Question 5

Which labeling information is REQUIRED on a sterile package according to best practices?

Accepted Answer

Sterilizer number, cycle number, load number, and date

Answer

Packages must be traceable; required label data includes sterilizer ID, load/cycle number, and the date processed to support recall and traceability.
