A nurse is preparing to change a sterile dressing on a postoperative chest wound. Which action demonstrates proper sterile technique during the dressing change procedure?
1Opening sterile packages by tearing the corners and allowing the contents to fall onto the sterile field
2Using sterile forceps to handle gauze and maintaining the tips of the forceps below the level of the hands✓ 정답
3Reaching across the sterile field to retrieve supplies from the opposite side of the setup
4Touching the outer 2-inch border of the sterile drape to reposition it during the procedure
해설
Maintaining forceps tips below hand level prevents contamination by gravity, demonstrating proper sterile technique. Other actions breach sterility by contaminating the field or supplies.
Core Nursing ExplanationKey Concept Analysis: This question tests the fundamental principles of Sterile technique during a dressing change. The core principle is to maintain a sterile field free from microorganisms to prevent surgical site infection (SSI). Any action that compromises this field, either by direct contact with non-sterile items or by allowing airborne contaminants to settle, is a breach of technique.
Answer Rationale: Option ② is correct because it adheres to the principle of Key Point!sterile-to-sterile contact. Sterile forceps are used to handle sterile gauze. Keeping the tips of the forceps pointed downward and below the level of the hands prevents contamination by gravity; if the tips are held upward, fluid or contaminants from the unsterile handles could run down onto the sterile tips and field.
Distractor Analysis:
Watch out for confusion! Option ①: Opening sterile packages by tearing and allowing contents to "fall" is incorrect. Proper technique involves carefully opening the package and dropping the contents onto the center of the sterile field from a safe height (about 6 inches) without touching the edges. Tearing and letting items fall uncontrolled risks contamination.
Option ③: Reaching across the sterile field is a major violation. It introduces unsterile clothing and arms over the sterile area, which can shed microorganisms onto the field. One must always approach the field from the side and never reach across it.
Option ④: The outer 1-inch (approximately 2.5 cm) border of a sterile drape is considered contaminated. Touching this border, even to reposition the drape, contaminates the gloves and subsequently the entire sterile field. The drape should be placed correctly from the start without adjustment.
Related Concepts: This integrates with concepts of medical asepsis (clean technique) vs. surgical asepsis (sterile technique), principles of setting up a sterile field, and infection control protocols for wound care.
Concept Summary
Concept
Key Principle
Common Error
Sterile Field
Only sterile items touch sterile items. The field must remain dry and in sight.
Turning back on field, leaving it unattended.
Opening Sterile Packages
Open away from body, drop contents onto center of field without touching.
Tearing wildly, holding package over field for too long.
Handling Sterile Instruments
Hold tips down, below waist/elbow level. Keep within visual field.
Pointing tips upward, passing over non-sterile areas.
Sterile Drape Borders
The outer 1-inch edge is non-sterile. Do not touch it with sterile gloves.
Using the edge to adjust position, contaminating gloves.
If sterile field is wet, touched, or out of sight, it is contaminated.
Anatomy, Physiology & Pharmacology Points
While primarily a skills-based question, understanding the physiology of wound healing (inflammatory, proliferative, maturation phases) underscores why sterility is critical. Introducing pathogens disrupts healing, increases inflammation, and can lead to systemic infection (sepsis).
Memory Tips
"Sterile above the waist, contaminated below." Keep sterile items above your waist and table level.
"1-inch edge is dead." The border of a sterile drape is not sterile.
"See it to believe it." If you didn't see the package being opened sterilely, it's not sterile.
High-Frequency NCLEX Topics
Sterile technique is a High Yield topic. The NCLEX-RN frequently tests on identifying breaks in technique, prioritizing actions to maintain sterility, and differentiating between clean vs. sterile procedures. Expect questions on urinary catheter insertion, central line dressing changes, and surgical wound care.
Watch Out for Question Variations!
The same concept can be tested as:
Priority Action: "The nurse is setting up a sterile field. Which action should the nurse take first?" (Answer: Perform hand hygiene).
Error Identification: "A nurse is observing a newly licensed nurse change a sterile dressing. Which action by the newly licensed nurse indicates a need for further teaching?"
Procedure Application: "When preparing to assist with a lumbar puncture, which item must the nurse ensure remains sterile?"
Nursing Clinical Practice GuideClinical Scenario: You are assigned to change the dressing on Mrs. Chen's median sternotomy wound on post-op day 2 following coronary artery bypass graft (CABG) surgery. The wound is covered with a sterile, occlusive dressing.
Nursing Intervention Strategy:
Assessment & Preparation: Perform hand hygiene. Assess the patient's pain level and pre-medicate if needed per order. Explain the procedure to gain cooperation. Gather all supplies (sterile dressing kit, gloves, cleansing solution, trash bag) before starting.
Creating the Sterile Field: Open the outer packaging of the sterile kit. Using the corners of the inner wrap, carefully lay down the sterile drape to create your field near the patient. Open additional sterile supplies (gauze, solution) by dropping them onto the center of the field.
Performing the Dressing Change: Don clean gloves to remove the old dressing and discard them. Perform hand hygiene again. Don sterile gloves. Cleanse the wound from the center outward using sterile gauze and solution, using one stroke per gauze piece. Allow the area to air dry. Apply the new sterile dressing without touching the side that will contact the wound.
Evaluation & Documentation: Assess the wound for signs of infection (redness, swelling, drainage, odor). Ensure the patient is comfortable. Document the procedure, wound appearance, and patient response.
Patient Safety and Precautions:
Never compromise the sterile field to save time or supplies. If contamination is suspected, start over.
Maintain the patient's privacy and warmth during the procedure.
Use Key Point!standard precautions in addition to sterile technique, as wound drainage may be present.
Nursing Procedure & Medication Flow
While this is a non-medication procedure, the flow is critical:
Procedure Flow: Hand Hygiene → Explain → Gather Supplies → Create Field (Sterile) → Remove Old Dressing (Clean Gloves) → Hand Hygiene → Cleanse Wound (Sterile Gloves) → Apply New Dressing → Dispose of Waste → Hand Hygiene → Document.
A Word from Your Senior Nurse
"Sterile technique is one of those non-negotiable nursing skills. In clinical practice, I've seen seasoned nurses gently coach new grads on keeping their forceps tips down. It's a simple act, but it protects your patient from a potentially life-threatening infection. When you're studying, don't just memorize the rules—visualize yourself doing it. Picture your hands, the field, the patient. That muscle memory of the mind will translate to confidence at the bedside and on your NCLEX. Remember, you are the last line of defense between the pathogen and the wound!"
Surgical Asepsis — Also called sterile technique. Practices that completely eliminate all microorganisms, including spores, from an object or area.
Sterile Field — A specified area that is considered free of all microorganisms. It is created by using sterile drapes and only sterile items are allowed to touch it.
Medical Asepsis — Also called clean technique. Practices that reduce the number and transfer of pathogens (e.g., hand hygiene, using clean gloves).
Surgical Site Infection — An infection that occurs after surgery in the part of the body where the surgery took place. Maintaining sterile technique is a primary prevention strategy.
Forceps — A handheld, hinged instrument used for grasping and holding objects. In sterile procedures, they are used to handle sterile items without direct hand contact.
