A nurse is preparing to change a sterile dressing on a postoperative abdominal wound. During the procedure, the nurse accidentally touches the sterile gauze with a non-sterile glove. What is the most appropriate nursing action?
1Continue with the procedure using the same gauze since it was only briefly contaminated
2Rinse the gauze with sterile saline solution to decontaminate it before use
3Discard the contaminated gauze and obtain new sterile supplies✓ 정답
4Use the gauze but apply antibiotic ointment to compensate for contamination
해설
Once sterile gauze is touched by a non-sterile glove, it is contaminated and must be discarded to prevent infection. Other options compromise sterile technique and increase infection risk.
In the context of postoperative wound care, maintaining a sterile field is a fundamental nursing responsibility to prevent surgical site infections. The core principle of surgical asepsis is that a sterile object remains sterile only when touched by another sterile object. The moment a sterile item comes into contact with a non-sterile surface, it is considered contaminated. This rule is absolute and does not account for the duration of contact or the visible cleanliness of the non-sterile object. An integrative review on infection prevention in the operative setting highlights that adherence to aseptic technique is a critical prerequisite for nurses to prevent contamination and subsequent infection [1]. The nurse's actions during a dressing change must reflect an unwavering commitment to these principles, as any breach can introduce pathogens directly to a vulnerable wound bed.
Analysis of the Contamination Event
When the nurse’s non-sterile glove touches the sterile gauze, a direct pathway for microbial transfer is created. The non-sterile glove harbors a multitude of microorganisms from the environment and the nurse's own skin flora. This contamination cannot be reversed or mitigated. The study on intraoperative infection prevention underscores that maintaining the integrity of the sterile field is a dynamic and continuous process that depends on the nurse's knowledge and strict adherence to protocol [1]. A momentary lapse, such as the one described, immediately breaks the sterile chain. The gauze is no longer safe for use on the wound, as it would serve as a vehicle for introducing bacteria, defeating the entire purpose of using a sterile dressing.
Evaluating the Incorrect Options
- Option 1: Continue with the procedure. This action directly violates the principle of sterile technique. The brief nature of the contamination is irrelevant; sterility is a binary state—it is either sterile or it is not. Proceeding would knowingly introduce a contaminated item to the wound, significantly increasing the risk of a surgical site infection.
- Option 2: Rinse with sterile saline. Sterile saline is used for wound cleansing or moistening a sterile dressing, but it does not have sterilizing properties. It cannot decontaminate a physically soiled or microbially laden object. Rinsing the gauze would not restore its sterility and would only create a false sense of security.
- Option 4: Use the gauze with antibiotic ointment. Topical antibiotic ointments are used to prevent or treat localized infections on intact skin or in a wound, but they are not a substitute for sterile technique. Applying ointment to a contaminated gauze does not neutralize the bacteria already present on the dressing. This approach would compound the error by adding a medication to a non-sterile application method, potentially trapping bacteria against the wound.
The Correct Nursing Action
The only appropriate and evidence-based response is to immediately discard the contaminated gauze and obtain new sterile supplies. This action aligns with the fundamental prerequisites for infection prevention, which require nurses to recognize a break in aseptic technique and take immediate corrective action to re-establish a sterile field [1]. The nurse must set up a new sterile field with fresh supplies to safely complete the dressing change. This practice demonstrates clinical competence and prioritizes patient safety by eliminating the direct risk of wound contamination.

Immediate Action
When a sterile item is touched by a non-sterile object, the item is instantly contaminated. The nurse must immediately stop the procedure, discard the contaminated gauze in the appropriate waste receptacle, and perform hand hygiene before obtaining new sterile supplies. The sterile field itself may also be compromised if the contaminated glove touched it; assess and replace the entire field if necessary.
Rationale and Risk
Non-sterile gloves carry skin flora and environmental pathogens. Any contact transfers these microbes to the gauze, which would then be introduced directly to a vulnerable surgical wound. Attempting to "clean" the gauze with saline or compensate with antibiotic ointment does not restore sterility and violates the core principle of surgical asepsis: sterile-to-sterile contact only.
Nursing Responsibilities
Recognize the break in technique immediately and verbalize the error to any assisting staff.
Discard all contaminated items and re-establish a new sterile field with fresh supplies.
Document the incident per facility policy, noting the breach and corrective actions taken.
Reflect on the cause of the break to prevent recurrence, such as adjusting equipment placement or improving body mechanics.
Surgical Asepsis — Techniques used to eliminate all microorganisms from an area, maintaining a sterile field where only sterile items contact each other.
Contamination — The introduction of microorganisms to a sterile surface or object, rendering it non-sterile and unsafe for use in invasive procedures.
Sterile Field — A designated area that is free of all microorganisms, created using sterile drapes and equipment, where strict aseptic technique is maintained.
