VA-BC Maintenance and Care 2

Question 1

When assessing a central venous catheter (CVC) dressing, which finding requires immediate intervention?

Accepted Answer

Visible moisture or drainage under a transparent semipermeable membrane dressing

Answer

Moisture or drainage under a TSM dressing compromises the sterile barrier and requires immediate dressing change to prevent infection.

Question 2

What is the recommended technique for flushing a peripheral IV catheter to maintain patency?

Accepted Answer

Pulsatile push-pause technique with normal saline

Answer

The pulsatile push-pause technique creates turbulence that removes fibrin and debris from the catheter lumen, maintaining patency.

Question 3

A patient's PICC line has a positive blood culture for Candida albicans. What is the most appropriate next step?

Accepted Answer

Remove the PICC line immediately and obtain peripheral cultures

Answer

Fungal catheter-related bloodstream infections require prompt catheter removal, as salvage is rarely successful and carries high morbidity.

Question 4

Which action best prevents air embolism during PICC dressing changes?

Accepted Answer

Having the patient perform the Valsalva maneuver or placing them in Trendelenburg position

Answer

Valsalva maneuver or Trendelenburg positioning increases intrathoracic pressure, reducing the risk of air entering the catheter during dressing changes.

Question 5

How often should needleless connector caps on a central venous catheter be changed according to INS standards?

Accepted Answer

No more frequently than every 96 hours and with each new IV tubing set change

Answer

INS standards recommend changing needleless connectors no more frequently than every 96 hours and in conjunction with IV administration set changes.
