The basic principles of aseptic technique
include the following except.
The edge of any sterile drape,
wrapper, or covering is considered
non-sterile.
Sterile surfaces contact only sterile
surfaces; non-sterile surfaces
contact only non-sterile surfaces.
Sterile gowns are considered sterile
only in front from neck line to table
level.
If any doubt exists about the sterility
of an item, consider it contaminated.
