What is the correct action when a Bowie-Dick test fails in a pre-vacuum steam sterilizer?
Answer: Remove the sterilizer from service, investigate the cause, and notify the appropriate personnel
A failed Bowie-Dick test indicates inadequate air removal in the pre-vacuum sterilizer; the unit must be taken out of service immediately and the cause investigated before returning to use.
Which factor is MOST critical in determining the efficacy of manual cleaning of surgical instruments?
Answer: The friction applied during scrubbing and thoroughness of cleaning
Manual cleaning relies heavily on mechanical action (friction) to physically remove bioburden, making proper scrubbing technique the most critical factor.
What is the recommended relative humidity level in the sterile storage area to protect package integrity?
Answer: 30–60%
AAMI guidelines recommend maintaining relative humidity between 30–60% in sterile storage to prevent package degradation, condensation, and microbial growth.
Which term describes instruments that are used to enter normally sterile tissue or the vascular system and require sterilization?
Answer: Critical devices
Critical devices (per the Spaulding Classification) contact sterile tissue or the vascular system and must be sterile before use to prevent serious infection.
A surgical instrument with a box-lock joint should be sterilized in what position?
Answer: Partially open to allow sterilant penetration into the joint
Box-lock instruments should be placed in the open or partially open position to allow steam or sterilant to contact all surfaces and penetrate the joint area.
What is the main hazard associated with ethylene oxide (EO) residue remaining on a device after sterilization?
Answer: It can cause chemical burns or toxic reactions in patients or staff
EO is a toxic, carcinogenic gas; inadequate aeration leaves residue that can cause chemical burns, hemolysis, and other toxic effects in patients and staff.
Which sterilization load configuration practice helps ensure adequate steam penetration throughout a wrapped tray?
Answer: Positioning trays on edge (vertical) or flat with space between items to allow steam circulation
Proper loading allows steam to circulate freely; trays should be positioned to facilitate steam penetration and condensate drainage, never packed too tightly.
