A. The specimen should be sent to pathology in a dry specimen container so that a frozen section can be completed.

D. Slander is spoken defamation.

C. During the sterilization process, the water within the lumen turns to steam and forces the air out of the lumen. This is important, because the air trapped within lumens can interfere with the sterilization process.
