The best way to transport item that have been processed using immediate use steam sterilization at the point of use is 

Rigid container designed for IUSS

Before an item can be placed in a liquid chemical sterile processing system they must be 

Cleaned

Both the Association of periOperative Registered Nurses and The Joint Commission recommend that 

The use of immediate use steam sterilization be minimized or decreased.

Items to be disinfected or sterilized  at the point of use must be 

Properly cleaned per Manufactureer’s Instructions for Use

Which of the following statements about immediate use steam sterilization is true?

It should be used only when there is not time to process items using the wrapped method

should not be immediate use steam sterilization sterilized unless there is a tracking system in place to trace the item to a patient

What is the length of time after sterilization that an IUSS item can be used?

IUSS items must be used immediately

Immediate use steam sterilization documentation should include

All the above

When transporting items that have been immediate use steam sterilized, it is required that

They be transported in such a manner that reduces the potential for contamination

When loading a steam sterilizer, basins should be 

Placed on edge

The higher the bioburden on an object

The more difficult it will be to sterilize

When combining load, hard goods should be placed on the top shelves to allow for more efficient removal  of the condensate.

False

Which of the following does not affect sterilization? 

How the user department tells the Sterile Processing (SP) staff to sterilize it.

The weakest part of a steam sterilizer is the 

door

The most common reason for steam sterilization failure is

Drain

How frequently should a sterilizer’s strainer be removed and cleaned?

Daily

One of the most frequent causes of a clogged drain screen is 

Tape

A sterilizer cart can be unloaded:

When an infrared device shows that the itmes have cooled to room temperature

Why is proper training for the safe and effective use of low-temperature sterilization important? 

Chemicals used to sterilize instruments have toxic properties

Aeration instructions for a medical device can be found in/on the
