Q

Give one example of a nursing practice that would illustrate one of the Principles of Surgical Asepsis.

A

Examples Include:
- Handle sterile objects that will touch open wounds or enter body cavities only with sterile forceps or sterile gloved hands

  • Nurses do not turn their backs on a sterile field.
  • Keep hair clean and short or enclose it in a net to prevent hair from falling on sterile objects. Microorganisms on the hair can make a sterile field unsterile.
  • Do not set up a sterile field ahead of time for future use.
  • Storage areas should be clean, dry, off the floor, and away from sinks.
