To measure tray weight

Question 3

How do Class 6 emulating indicators differ from Class 5 integrating indicators?

Accepted Answer

Class 6 responds to one specific cycle; Class 5 responds across a range of cycle types and correlates with BI performance

Answer

Class 6 is less accurate

Answer

They are identical

Answer

Class 6 only works with ETO

Question 4

What records must be maintained for each sterilization cycle?

Accepted Answer

Complete documentation including date, time, sterilizer ID, cycle number, load contents, physical parameters, operator, and monitoring results

Answer

Only date and time

Answer

Only BI results

Answer

Records only needed for implants

Question 5

What is the significance of the drying phase in steam sterilization?

Accepted Answer

Wet packages allow microbial migration through packaging, compromising sterility

Answer

Optional for convenience

Answer

Only prevents rust

Answer

Further sterilizes items

Question 6

When must BI results be available for implantable device loads?

Accepted Answer

Before the implant is used, requiring rapid-readout BIs with 1-3 hour results

Answer

Not required for implants

Answer

Next day is fine

Answer

Only chemical indicators needed
