ATI RN Fundamentals 2019 with NGN - Exam 2 | Nurselytic

Correct Answer: D

Rationale: The correct answer is D: Cleanse the site with chlorhexidine before dressing changes. This is essential to prevent infection as chlorhexidine is an effective antiseptic that kills bacteria on the skin. First, washing the site with chlorhexidine reduces the risk of introducing bacteria into the catheter during dressing changes. Second, it helps maintain a sterile environment around the catheter insertion site, reducing the chances of infection. Third, it is recommended by evidence-based practice guidelines for central venous catheter care.

Incorrect

Choices:
A: Changing the dressing only when visibly soiled increases the risk of infection as it may not be done frequently enough to prevent bacterial growth.
B: Flushing the catheter with saline every 24 hours is important for maintaining patency but does not directly prevent infection.
C: Using clean gloves for dressing changes is necessary but does not address the need for antiseptic cleansing of the site.
