Sterile Technique And Sterile Field - NCLEX Rn
- What is the correct action if a sterile item touches an unsterile surface during setup?
- Discard the item and replace it with a sterile item. Sterile items become contaminated upon contact with unsterile surfaces, necessitating immediate replacement to maintain asepsis.
- What is the correct minimum distance to hold the sterile solution bottle above the sterile field while pouring?
- About – inches (– cm) above the container/field. This height allows steady pouring without splashing or risking bottle contact, maintaining solution and field sterility.
- What is the correct response if a sterile drape becomes wet during a procedure?
- Consider it contaminated and replace the drape/field. Moisture allows microbial strike-through, breaching the barrier and requiring a new dry field to ensure sterility.
- What is the correct action if you suspect a break in sterile technique but did not see contamination?
- Assume contamination and correct it immediately (replace/recreate field). Suspected breaks must be treated as actual to uphold the principle of absolute sterility in preventing infections.
- What is the correct action if the label of a sterile solution bottle faces the sterile field while pouring?
- Turn the label away from the field to prevent wetting it. Turning the label preserves its readability by avoiding drips that could obscure important information like expiration.
- Which area of a sterile gown is considered contaminated during sterile procedures?
- Back of the gown, below waist, and cuffs are contaminated. These areas are either handled, below visibility, or near non-sterile zones, increasing contamination risk during procedures.
- What is the correct hand position after performing a surgical scrub and donning sterile attire?
- Keep hands in sight and above waist level, away from the body. This position keeps hands visible and away from contaminated areas below the waist or against the body.
- What is the correct action if a sterile field is left unattended or out of sight?
- Consider it contaminated and set up a new sterile field. Unattended fields risk unseen contamination from air currents, personnel, or environmental factors.
- Which option best describes how to pass a sterile object to another sterile team member?
- Pass it directly, keeping it within the sterile field and in view. Direct passing within view ensures the object stays in the sterile zone without risking drops or unseen contamination.
- What is the correct direction to open the side flaps of a sterile package during setup?
- Open side flaps next, then open the flap closest to you last. This sequence minimizes arm extension over the field, reducing the risk of airborne or contact contamination.
- Which option is correct for adding sterile instruments to a sterile field during setup?
- Use sterile transfer forceps or drop technique; do not reach over field. These methods avoid extending non-sterile arms over the field, which could shed particles or cause direct contact.
- Identify the correct action if you must turn while wearing a sterile gown and gloves.
- Turn back-to-back or front-to-front with another sterile person. These orientations keep sterile fronts facing each other or backs exposed, preventing cross-contamination.
- Identify the correct action if your sterile glove touches your gown below waist level.
- Consider the glove contaminated; remove and replace the glove. Areas below waist level are considered contaminated, transferring microbes to the glove upon contact.
- Which action maintains sterility when pouring sterile solution into a sterile container?
- Pour without splashing; keep the bottle above the container. Controlled pouring minimizes splashing, which could aerosolize contaminants, while elevation prevents bottle contact with the field.
- Which part of sterile gloves is considered contaminated after donning?
- The glove cuffs are considered contaminated. Cuffs contact skin during donning, rendering them non-sterile despite the rest of the glove maintaining sterility.
- Identify the correct action if a nonsterile person reaches over the sterile field to adjust equipment.
- Consider the field contaminated; recreate the sterile field. Reaching over introduces airborne contaminants or particles from non-sterile attire into the field.
- Which technique prevents contamination when adding a sterile item to a sterile field?
- Drop the item onto the field without reaching over it. Dropping avoids extending non-sterile arms or hands over the field, preventing particle shedding or direct contamination.
- Which area of a sterile gown is considered sterile after donning it correctly?
- Front from chest to waist and sleeves from cuff to inches above elbow. These areas are protected during donning and remain unexposed to non-sterile surfaces, ensuring they stay aseptic.
- What is the correct action after removing the cap from a sterile solution bottle?
- Place the cap with the inside facing up on a clean surface. Placing the cap interior up protects the sterile inner surface from airborne contaminants during pouring.
- What is the correct direction to open a sterile package first when setting up a field?
- Open the flap farthest from you first. Opening the distant flap first prevents reaching over and contaminating the exposed sterile surface.
- Which option indicates a sterile package is contaminated before opening it?
- Tears, punctures, wetness, broken seal, or expired indicator. These signs indicate potential breaches in packaging integrity, allowing microbial entry before use.
- What principle explains why moisture contaminates a sterile field?
- Strike-through: fluid carries microorganisms through barriers. Strike-through occurs as liquids wick microbes through porous materials, compromising the sterile barrier.
- Which parts of a sterile package wrapper are considered contaminated once opened?
- The outer inch border of the wrapper is contaminated. The border is handled during opening, introducing potential contaminants from hands or air exposure.
