VABC Infection Prevention 3

Question 1

A nurse prepares to access an implanted port. Which skin antiseptic and contact time is recommended by INS standards before needle insertion?

Accepted Answer

>0.5% chlorhexidine in alcohol with 30-second scrub and full dry time

Answer

INS standards recommend chlorhexidine gluconate (>0.5%) in alcohol applied with friction for at least 30 seconds, followed by complete drying before accessing an implanted port.

Question 2

Which factor most significantly increases a patient's risk of developing a CLABSI?

Accepted Answer

Use of a triple-lumen catheter versus a single-lumen catheter

Answer

Multi-lumen catheters have more access points, increasing opportunities for hub contamination and microbial entry, which raises CLABSI risk compared to single-lumen catheters.

Question 3

During a central line dressing change, a nurse notes the transparent semipermeable membrane (TSM) dressing is lifting at the edges but the site appears clean. The correct action is to:

Accepted Answer

Change the dressing immediately, as a non-intact dressing increases infection risk

Answer

A dressing that is no longer intact, wet, or lifting compromises the sterile barrier and must be changed promptly regardless of scheduled interval.

Question 4

Which of the following is the most appropriate catheter site for reducing CLABSI risk in non-tunneled central venous catheters in adult patients?

Accepted Answer

Subclavian vein

Answer

The subclavian site is associated with the lowest CLABSI and thrombosis rates among non-tunneled CVC insertion sites in adults per CDC guidelines.

Question 5

What is the purpose of performing daily 'line necessity' reviews for central venous catheters?

Accepted Answer

To ensure catheters are removed promptly when no longer clinically needed, reducing infection risk

Answer

Daily necessity reviews are a core CLABSI bundle element; prompt removal of unnecessary catheters is one of the most effective ways to reduce infection risk.
