Monitoring & QAQuestion 63 of 100
A technician finds a box of chemical indicators labeled for use only in a cycle of 270 degrees F for 4 minutes. What type of indicator is this?
a.An emulating indicator designed and verified for one specific cycle, reacting to all critical variables at the stated values of that cycle
b.An indicator used only in ethylene oxide sterilizers
c.An indicator that replaces the daily biological indicator
d.An external indicator used to identify the sterilizer number
Explanation
Class 6 emulating indicators are cycle specific, meaning an indicator labeled for 270 degrees F and 4 minutes may be used only for that cycle, and they respond to all critical variables at the stated values. They exist for multiple sterilization methods, not just ethylene oxide. No chemical indicator of any class replaces biological monitoring, and identifying the sterilizer is a labeling function.
