What is the proper technique for removing a PICC line?
Answer: Place the patient supine, apply steady gentle traction, and measure the removed catheter length against the documented insertion length
PICC removal requires supine positioning, steady gentle traction to prevent catheter breakage, and length verification to confirm complete removal.
When should a central venous catheter be replaced over a guidewire versus a new site insertion?
Answer: Guidewire exchange when the catheter is mechanically defective but there is no evidence of infection at the existing site
Guidewire exchange is appropriate for mechanical catheter defects (malposition, damage) when there is no evidence of catheter-related infection at the existing site.
What is the significance of catheter-to-vein ratio in vascular access device selection?
Answer: A ratio exceeding 45% increases the risk of venous thrombosis and should be avoided
A catheter-to-vein ratio exceeding 45% significantly increases the risk of venous thrombosis by impeding blood flow around the catheter.
How should the CRNI manage a patient who develops phlebitis at a peripheral IV site?
Answer: Remove the catheter, apply a warm compress, document the phlebitis grade, and restart at a new site
Phlebitis management requires catheter removal, warm compress application for comfort and blood flow promotion, documentation using a standardized scale, and IV restart at a new site.
What is the recommended practice for blood sampling from a central venous catheter?
Answer: Pause infusions, discard an appropriate waste volume, obtain the sample, flush, and resume infusions
Blood sampling from CVCs requires pausing infusions, discarding a waste volume to clear the line of infusate, obtaining the specimen, and flushing afterward to maintain patency.
What assessment should the CRNI perform before each use of an implanted port?
Answer: Assess the site for signs of infection, port stability, skin integrity, and swelling; confirm blood return after access
Pre-access port assessment includes inspection for infection signs, palpation for stability and fluid collection, skin integrity evaluation, and blood return confirmation after accessing.
