VABC Infection Prevention 2

Question 1

Which organism is most commonly responsible for catheter-related bloodstream infections (CRBSI) in vascular access patients?

Accepted Answer

Staphylococcus epidermidis

Answer

Coagulase-negative staphylococci, particularly Staphylococcus epidermidis, are the most frequent cause of CRBSI due to their ability to form biofilms on catheter surfaces.

Question 2

What is the recommended maximum number of days a peripheral IV catheter should remain in place in adults before elective rotation to a new site?

Accepted Answer

72–96 hours

Answer

CDC guidelines recommend replacing peripheral IV catheters every 72–96 hours in adults to reduce the risk of phlebitis and infection.

Question 3

A patient's PICC insertion site shows erythema, warmth, and purulent drainage 10 days post-insertion. The FIRST priority action by the vascular access nurse is to:

Accepted Answer

Notify the provider and prepare for catheter removal

Answer

Signs of local infection with purulent drainage indicate a likely infected catheter, requiring prompt provider notification and evaluation for removal.

Question 4

Chlorhexidine-impregnated sponge dressings are indicated primarily to reduce which complication of central venous catheters?

Accepted Answer

Catheter-related bloodstream infection

Answer

Chlorhexidine-impregnated sponge dressings reduce microbial colonization at the insertion site, thereby lowering the risk of CRBSI.

Question 5

When performing a central line dressing change, which action is most important for infection prevention?

Accepted Answer

Using sterile gloves and a sterile field throughout the procedure

Answer

Maintaining sterile technique with sterile gloves and a sterile field during dressing changes is fundamental to preventing catheter site contamination.
