A nurse is preparing to perform a sterile dressing change on a client's central venous catheter (CVC). To reduce the risk of a central line-associated bloodstream infection (CLABSI) and prevent catheter dislodgment, place the following steps in the correct chronological order.
- 1Don a face mask and instruct the client to turn their head away from the insertion site.
- 2Remove the old dressing by gently pulling the edges toward the catheter insertion site.
- 3Discard the old dressing and clean gloves, perform hand hygiene, and don sterile gloves.
- 4Scrub the insertion site with a chlorhexidine applicator using friction and allow it to air dry completely.
- 5Apply a new sterile transparent occlusive dressing over the insertion site and secure the hub.
Cevap
The correct sequence begins with donning a mask and directing the client's face away, followed by removing the old dressing. The nurse then transitions to sterile gloves, cleanses the site with chlorhexidine (allowing it to dry), and finally applies a new transparent occlusive dressing.
Changing a central line dressing requires strict adherence to sterile technique to prevent CLABSI. Masking protects the site from respiratory droplets. The old dressing is removed carefully toward the site to prevent dislodging the catheter. A sterile field is then established by donning sterile gloves. Chlorhexidine is applied with friction to destroy microorganisms and must dry completely to achieve its chemical antisepsis effect. Finally, a sterile occlusive dressing seals the site.
