 1. CJD can be transmitted from one patient to another through contaminated medical equip-

 2. The central issue with reprocessing single-use items is not the patient and personal safety of

 4. The more a sterile-wrapped package is handled, the greater the risk for contamination.

 5. Sterile items should be stored in areas that are separate from those used to store clean,

 6. Growth of bacteria in a test monitor culture indicates that the sterilization process was

 7. A chemical monitor may be placed on the outside or the inside of a package, but never both.
