Question 1

Which type of packaging material is used for low-temperature hydrogen peroxide plasma sterilization?

Accepted Answer

Nonwoven polypropylene pouches or Tyvek-compatible pouches

Answer

Hydrogen peroxide plasma sterilization requires synthetic, non-cellulose-based materials such as polypropylene nonwovens or Tyvek; paper and cellulose absorb the sterilant.

Question 2

What is the maximum recommended weight for a wrapped instrument tray set according to AAMI guidelines?

Accepted Answer

7.5 kg (16.5 lbs)

Answer

AAMI ST79 recommends instrument sets not exceed 7.5 kg (approximately 16.5 lbs) to ensure adequate sterilant penetration and prevent packaging damage.

Question 3

During storage of sterile packs, which environmental condition poses the greatest risk to package integrity?

Accepted Answer

High humidity and moisture exposure

Answer

High humidity can compromise the microbial barrier of packaging materials, especially paper-based products, increasing the risk of contamination.

Question 4

The 'event-related sterility' concept means that sterility is maintained until:

Accepted Answer

The package is physically compromised or contaminated

Answer

Event-related sterility means a properly packaged item remains sterile indefinitely until an event (such as physical damage or moisture exposure) compromises the package.

Question 5

Which statement about double-pouching instruments is CORRECT?

Accepted Answer

The inner pouch must be sized to fit without folding inside the outer pouch

Answer

The inner pouch must fit flat inside the outer pouch without folding to ensure the sterilant can penetrate and reach the instrument.
