latest practices and technologies
A surgical instrument set is needed urgently, but the standard sterilization cycle takes 30 minutes.
Which method should you use? *** Immediate-use sterilization
During a routine inspection, you notice a small crack in a surgical instrument. What should you do? ***
Report it and remove it from service for repair or replacement

action? *** Remind the coworker about the importance of PPE
An instrument package is wet after sterilization. What should you do? *** Repack and resterilize the
instruments

*** Refer to the manufacturer's instructions for use (IFU)
,What is a biological indicator? *** A preparation of living spores resistant to the sterilizing agent
What is the purpose of a chemical indicator on a package? *** To differentiate between sterilized and
unsterilized items
What are some devices that monitor the functions of sterilizers? *** Gauges, thermometers, timers,
and/or recorders
What parameter affects all other dependent parameters in ethylene oxide sterilization? *** Gas

*** The surface and crannies for gross soil, jaws and teeth of hinged instruments, sharpness of cutting
edges
, What is the purpose of the ultrasonic washer in the decontamination process? *** To remove fine soil
from surgical instruments after manual cleaning and before sterilization
What is the purpose of the Decontamination Area in a Sterile Processing Department? *** To clean and
decontaminate reusable equipment, instruments, and supplies
What happens to items after assembly or sterilization in a Sterile Processing Department? *** They are
transferred to the sterile storage area
What are the major functions carried out in the distribution area? *** Case cart preparation and
delivery, exchange cart inventory, telephone-order and requisition-order filling, and patient care
equipment delivery

What is the significance of the last two letters of a singular suffix in medical terminology? *** They
determine the plural form of the word
How are medical terms with multiple roots constructed? *** By using multiple roots with a combining
vowel in between
What is the function of a suffix in a medical term? *** To define whether the word is a noun, verb, or
adjective
What is the purpose of a prefix in a medical term? *** To indicate a location, direction, type, quality, or
quantity
