CRNI Vascular Access Device Management 4

Question 1

A patient with a PICC line develops a fever of 38.9°C and chills during an infusion. What is the priority nursing action?

Accepted Answer

Stop the infusion and notify the provider immediately

Answer

Fever and chills during infusion through a central vascular access device suggest catheter-related bloodstream infection (CRBSI), requiring immediate cessation of infusion and provider notification.

Question 2

Which technique is used to remove air from IV tubing before connecting to a central venous catheter?

Accepted Answer

Purging the line by allowing fluid to flow through until air-free

Answer

Priming (purging) the IV tubing before connection removes air and prevents air embolism, a serious complication of central venous catheter use.

Question 3

A nurse is caring for a patient with an implanted port. Which needle type must be used to access an implanted port?

Accepted Answer

Non-coring (Huber) needle

Answer

Non-coring (Huber) needles have an angled bevel that displaces the port septum without cutting it, preserving septum integrity for repeated access.

Question 4

When assessing a peripheral IV site, which finding requires immediate catheter removal?

Accepted Answer

Mild redness extending 2 cm from the insertion site

Answer

Redness extending 2 cm from the insertion site indicates phlebitis (Grade 2 or higher), which requires catheter removal per INS standards.

Question 5

A tunneled central venous catheter has a dacron cuff. What is the primary purpose of this cuff?

Accepted Answer

To act as a bacterial barrier and anchor the catheter subcutaneously

Answer

The dacron cuff promotes fibrous tissue ingrowth, anchoring the tunneled catheter subcutaneously and providing a mechanical barrier against bacterial migration.
