Scrub vigorously with 70% alcohol or CHG-alcohol for at least 5–15 seconds and allow to dry

Answer

Vigorous mechanical scrubbing with 70% isopropyl alcohol or CHG-alcohol for 5–15 seconds followed by drying is required to disinfect needleless connectors and prevent CLABSI.

Question 2

A chlorhexidine gluconate (CHG) patch/disc is indicated for use at which type of IV access site?

Accepted Answer

Central venous access device (CVAD) insertion sites

Answer

CHG-impregnated dressings are indicated for CVAD insertion sites to reduce the risk of CLABSI by providing sustained antimicrobial activity.

Question 3

How often should the administration set (IV tubing) for continuous infusions be changed in the absence of blood product or lipid administration?

Accepted Answer

Every 72–96 hours

Answer

INS and CDC recommend changing primary and secondary continuous administration sets no more frequently than every 96 hours (4 days) unless indicated otherwise.

Question 4

When should administration tubing used to infuse blood or blood components be changed?

Accepted Answer

After every unit or after 4 hours, whichever comes first

Answer

Blood administration tubing should be changed after each unit of blood product or after 4 hours of infusion time, whichever occurs first, to reduce bacterial proliferation risk.

Question 5

What is the first nursing action when a peripheral IV site shows signs of infiltration?

Accepted Answer

Discontinue the IV and remove the catheter

The immediate action for IV infiltration is to stop the infusion and remove the catheter to prevent further tissue damage from continued fluid extravasation.
