A nurse is preparing to change a sterile dressing on a patient's surgical wound. During the procedure, the nurse accidentally touches the outer wrapper of a sterile gauze package with contaminated gloves. What is the most appropriate action for the nurse to take?

해설
When contaminated gloves touch sterile supplies, the sterile field is compromised. The nurse must remove gloves, perform hand hygiene, and don new sterile gloves to maintain asepsis and prevent infection.

Core Nursing Explanation Key Concept Analysis: This question tests the fundamental principle of Surgical asepsis (Sterile technique). The core concept is that sterility is absolute—an item is either sterile or contaminated. There is no "partially sterile." The outer wrapper of a sterile package is considered non-sterile. Once a contaminated object (like a used glove) touches a sterile item or its wrapper, the sterility of the item inside is considered compromised because contamination can be transferred through the wrapper.

Answer Rationale: Key Point! The correct action is to remove the contaminated gloves, perform hand hygiene, and don new sterile gloves. This sequence is crucial because the gloves are now contaminated from touching the non-sterile wrapper. Continuing with those gloves would transfer microorganisms to the new sterile gloves or directly to the wound. The nurse must start the gloving process over with clean hands to re-establish a sterile field and protect the patient from a Surgical site infection (SSI).

Distractor Analysis:
Watch out for confusion! Option 1 is incorrect because the principle of sterility is violated. Even though only the wrapper was touched, the action was performed with contaminated gloves, breaking the chain of asepsis. The integrity of the sterile field is no longer guaranteed.
Option 3 is a critical error. Alcohol-based hand sanitizer is for use on clean skin, not on gloves. It does not effectively decontaminate gloves, and using it would not restore sterility. This action is not supported by infection control guidelines.
Option 4 prioritizes task completion over patient safety. Completing the dressing change with compromised supplies introduces a high risk of infection. Documentation is important, but it follows corrective action, not replaces it. The immediate priority is to prevent harm by re-establishing a sterile field.

Related Concepts: This scenario connects to broader principles of Infection prevention and control and the nurse's role in maintaining a sterile field. It also touches on the nursing process: the nurse must assess the break in technique, diagnose a risk for infection, plan and implement corrective action (re-gloving), and evaluate by ensuring the procedure is completed without further contamination. Concept SummarySterile Field: A microorganism-free area prepared for procedures. Anything outside the 1-inch border is considered non-sterile. • Sterile Principle: If there is any doubt about the sterility of an item, it is considered contaminated. • Chain of Asepsis: A break at any point (e.g., contaminated glove touching a wrapper) compromises the entire process. • Corrective Action: Stop immediately, remove contaminated items, re-clean (hand hygiene), and re-establish sterility. Side-by-Side Comparison!
Surgical Asepsis (Sterile Technique)Medical Asepsis (Clean Technique)
Goal: Eliminate all microorganisms from an area/object.Goal: Reduce the number and spread of pathogens.
Used for: Invasive procedures (surgery, dressing change, catheter insertion).Used for: Routine patient care (vital signs, bed bath, non-sterile dressing).
Key Rule: Sterile touches sterile. A single break contaminates the field.Key Rule: Clean to clean, clean to dirty, dirty to dirty.
Example Action in this Scenario: Must discard the potentially contaminated gauze package and re-glove.Example Action: If a clean glove touched a bedrail, you might just continue with the same glove for that task.
Anatomy, Physiology & Pharmacology Points • While not directly about anatomy, this principle protects the body's first line of defense—the Skin—from being breached by pathogens during wound care. • The physiological rationale is to prevent the inflammatory and immune responses that lead to infection, delayed healing, and systemic complications. Memory TipsMnemonic: "When in doubt, throw it out!" If you question sterility, consider it contaminated. • Association: Think of the sterile field as a "bubble." Poking it with a dirty needle (contaminated glove) pops the bubble. You have to create a new one. High-Frequency NCLEX Topics Principles of surgical asepsis are extremely high-yield for NCLEX. You will be tested on: 1. Setting up and maintaining a sterile field. 2. Proper donning and removal of sterile gloves (open vs. closed method). 3. Prioritizing actions when a break in technique occurs (as in this question). 4. Differentiating sterile vs. clean procedures. Watch Out for Question Variations! • Instead of "touching a wrapper," the question might involve: "The nurse's sterile glove brushes against the patient's bed linen." The action is the same—the glove is now contaminated. • The question could shift to priority-setting: "What should the nurse do first?" The answer is always to stop the contaminating action (remove the glove) before anything else. • It could be framed as a patient education topic: "A nurse is teaching an assistive personnel about sterile technique. Which statement by the AP indicates understanding?" A correct statement would be, "If I touch the edge of the sterile drape, I should tell the nurse so the supplies can be changed."

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are in a medical-surgical unit changing the dressing on a patient's abdominal incision from a recent colectomy. Your sterile field is set up on the bedside table. As you reach for a 4x4 gauze, the cuff of your sterile glove touches the plastic outer wrapper of the gauze package, which is lying just outside the sterile field.

Nursing Intervention Strategy: 1. Assessment & Stop: Immediately recognize the break in technique. Verbally acknowledge it to any assisting staff ("I've contaminated my glove"). 2. Safe Removal: Carefully remove the contaminated glove by grasping the cuff and pulling it inside out, holding it in the still-gloved hand. Then, remove the remaining sterile glove by sliding fingers inside the cuff. This contains the contamination. 3. Hand Hygiene: Perform hand hygiene (hand rub or wash) according to protocol. 4. Re-establish Sterility: Open a new pair of sterile gloves using proper technique. Also, consider the gauze package that was touched. Since the outer wrapper was touched with a contaminated glove, it is safer to discard that entire package and open a new one to ensure no cross-contamination occurred when opening it. 5. Proceed & Evaluate: Complete the dressing change. Afterward, evaluate the wound in subsequent shifts for any signs of infection (redness, swelling, purulent drainage).

Patient Safety and Precautions: • Never attempt to "clean" a contaminated glove or item with alcohol or antiseptic. This is not effective for restoring sterility. • The one-inch border around a sterile drape is considered non-sterile. If an ungloved hand or a contaminated object touches this border, the entire drape is not necessarily contaminated—only the item that touched it is. However, if a sterile-gloved hand touches the border, that glove is now contaminated. • Always prepare your sterile field in a clean, dry, waist-level area away from traffic to minimize accidental contamination. Nursing Procedure & Medication Flow Sterile Gloving Procedure (Open Method) After Contamination: 1. After hand hygiene, open the sterile glove package on a clean, dry surface. 2. With your non-dominant hand, pick up the first glove by its folded cuff (the inside, which will touch your skin, is not sterile). 3. Guide your dominant hand into the glove, pulling the cuff up without touching the outside of the glove. 4. Slide your gloved fingers under the cuff of the second glove to pick it up without touching its outside. 5. Guide your non-dominant hand into the glove, pulling it on securely. 6. Adjust fingers, interlocking if necessary, without touching non-sterile surfaces. A Word from Your Senior Nurse "In the fast-paced clinical environment, it's easy to feel pressured to 'just get the task done,' especially when you're busy. But remember this: taking the extra 60 seconds to change your gloves and get new supplies isn't a delay—it's the essence of safe, quality nursing care. Protecting your patient from a preventable infection is one of your most critical roles. On the NCLEX, they are testing your commitment to these fundamental safety principles. In practice, that commitment builds trust with your patients and your team. Always err on the side of caution with sterility!"
