Study Notes

Sterile Technique - Final Exam Study Guide

  • Outcome: 80% of nurses will demonstrate knowledge on preparing and maintaining a sterile field, evidenced by a 80% or higher score on the post-test.

Objectives

  • Define surgical conscience.
  • Summarize sterile technique principles.
  • Describe opening sterile items (containers, wrapped packages, peel-packs).
  • Describe practices to identify, address, and correct sterile field contamination.

Sterile Technique Principles

  • Prepare the sterile field as close as possible to use time.
  • Prepare in the location of use.
  • Only one patient per sterile field.
  • Use sterile items within the sterile field.
  • A contaminated field is a field where unsterile items have contacted it.
  • Question the sterility of doubtful items; consider them contaminated.
  • Sterile gown is considered sterile from chest to sterile field / 2 inches above elbow.
  • Areas below the table and bed are considered contaminated.
  • Cover the field if not used immediately or during activity peaks (positioning).
  • Use surgical drapes to establish fields.
  • Limit movement around and within the field.
  • Prevent cross-contamination by separating sterile fields/instrumentation for procedures with multiple wound classifications.

Hand Hygiene

  • Hand hygiene is the most effective method to prevent transmissions of pathogens.

Opening Sterile Items

  • Inspect packaging for integrity and proper indicators.
  • Verify that the package is intact and sterility conditions have been met.
  • Indicators include sterility and package/product integrity.

Additional Information

  • Correctly opening rigid containers, small wrapped items, and peel packs is detailed, including steps and required actions.
  • Items containing filters require further inspection for integrity.
  • Packaging material quality, storage conditions, and handling affect sterility.
  • Surgical hand antisepsis (scrub/rub) reduces skin microbes before sterile gown/gloves.
  • Follow manufacturers' instructions for use.
  • Factors that impact field sterility are included, like expiration dates, chemical indicators, and tampering evidence (locks, seals etc).
  • Circumstances where you might need to contact infection preventionists are touched upon (policies regarding situations where items or persons may have been in contact with contaminants).
