Question 1

Which antiseptic is preferred for central line dressing site preparation in adults who are not allergic?

Accepted Answer

Chlorhexidine gluconate 2% with 70% isopropyl alcohol

Answer

Chlorhexidine gluconate 2% combined with 70% isopropyl alcohol is recommended as the primary skin antiseptic for CVC insertion and dressing changes due to superior persistent antimicrobial activity.

Question 2

When should a chlorhexidine-impregnated dressing (CHG disk) be used on a CVC site?

Accepted Answer

When the CLABSI rate remains above goal despite standard practices

Answer

CDC and INS guidelines support CHG-impregnated dressings as an additional measure when CLABSI rates remain elevated despite implementation of standard prevention bundles.

Question 3

A patient with a non-tunneled CVC develops redness, warmth, and purulent drainage at the insertion site. Which step should be taken FIRST?

Accepted Answer

Notify the provider and obtain site cultures before removing the catheter

Answer

The provider must be notified and cultures obtained before catheter removal so appropriate decision-making regarding salvage versus removal can be made.

Question 4

What is the correct order of steps when using a needleless connector prior to medication administration?

Accepted Answer

Scrub the hub for 5-15 seconds, allow to dry, then access

Answer

Scrubbing the needleless connector for 5-15 seconds with alcohol or CHG and allowing it to dry before access ('scrub the hub') reduces microbial contamination.

Question 5

An implanted port that is not in active use should be accessed and flushed at which interval to maintain patency?

Accepted Answer

Every 3 months

Answer

INS standards recommend flushing implanted ports every 3 months when not in use to maintain patency and prevent occlusion.
