Monitoring & QAQuestion 61 of 100
A Class 1 chemical indicator is applied to the outside of every wrapped tray. What does it tell the user?
a.That all critical parameters of the cycle were met
b.That the contents are sterile and safe for patient use
c.That the package has been exposed to a sterilization process and distinguishes processed from unprocessed packages
d.That air was successfully removed from the chamber
Explanation
Class 1 process indicators, such as autoclave tape and preprinted pouch indicators, only distinguish processed from unprocessed items and do not measure whether the cycle was adequate. Confirming that all critical variables were met is the role of Class 5 integrating indicators, and air removal is verified by a Class 2 Bowie-Dick test. Sterility is never established by any single indicator.
