Question 1

A patient receiving a continuous 5-FU infusion via ambulatory pump reports that the pump alarmed and the site feels warm. What is the nurse's priority?

Accepted Answer

Stop the infusion, assess for extravasation, and notify the provider

Answer

Warmth at the infusion site during chemotherapy administration suggests possible extravasation, requiring immediate cessation and assessment.

Question 2

Which intervention helps prevent fibrin sheath formation on a central venous catheter?

Accepted Answer

Flushing with 10 mL normal saline using a pulsatile push technique after each use

Answer

Pulsatile flushing with normal saline creates turbulence that dislodges debris and prevents fibrin accumulation on catheter walls.

Question 3

The nurse suspects a PICC line has migrated based on the patient's complaint of gurgling sounds in the ear during infusion. What does this indicate?

Accepted Answer

Catheter tip has migrated into the jugular vein

Answer

Gurgling or swishing sounds in the ear during PICC infusion indicate catheter tip migration into the jugular vein, requiring imaging confirmation and repositioning.

Question 4

Which dressing change frequency is recommended for a tunneled central venous catheter exit site according to current evidence-based guidelines?

Accepted Answer

Every 7 days with transparent semi-permeable membrane dressing (unless soiled)

Answer

Current INS and CDC guidelines recommend transparent dressing changes every 7 days for tunneled CVC exit sites unless the dressing becomes wet, soiled, or loose.

Question 5

A patient with a new PICC line develops sudden onset of dyspnea, hypotension, and a 'sucking' sound during catheter manipulation. What complication is occurring?

Accepted Answer

Air embolism

Answer

Air embolism can occur during open central catheter manipulation and presents with sudden dyspnea, hypotension, and a mill-wheel murmur or sucking sound.
