A nurse is observing a newly licensed nurse prepare a sterile field for the insertion of a urinary catheter. Which of the following actions by the newly licensed nurse indicates an understanding of surgical asepsis?

Surgical asepsis, or sterile technique, is required for procedures that involve entering a sterile body cavity, such as the bladder. Nursing care during sterile procedures such as urinary catheter insertion requires strict adherence to surgical asepsis to prevent introduction of microorganisms into the urinary tract. Surgical asepsis (sterile technique) involves maintaining an environment free from all microorganisms during procedures that bypass the body’s normal defenses. Proper handling of sterile fields, supplies, and equipment is essential to reduce the risk of healthcare-associated infections such as catheter-associated urinary tract infections. Understanding sterile boundaries is critical for safe practice. Rationale: A. The nurse should open the outermost flap of a sterile kit away from their body. This prevents the nurse from having to reach over the sterile field later in the process, which would contaminate the field with microorganisms falling from the nurse's sleeves or arms. B. The outer 1-inch border of a sterile field is considered contaminated. Placing used or "dirty" supplies on the outer aspect of the field risks cross-contaminating the sterile items in the center. Used supplies should be discarded in a proper waste receptacle away from the sterile work surface. C. The work surface must be at or above waist level. Any sterile object or field held below the waist is considered contaminated because it is out of the nurse's range of vision, and there is a higher concentration of microorganisms closer to the floor. D. Squeezing the lubricant onto the sterile field is a correct action. Sterile kits often contain a packet of lubricant. The nurse can carefully open the packet and "drop" or squeeze the contents onto the sterile tray without touching the packet to the sterile surface. This ensures the lubricant remains sterile and ready for use when the catheter is prepared.
