VA-BC Catheter Types 2

Question 1

Which catheter type is specifically designed for long-term hemodialysis access when arteriovenous fistula creation is not possible?

Accepted Answer

Tunneled cuffed hemodialysis catheter

Answer

Tunneled cuffed hemodialysis catheters are designed for long-term dialysis access, with a Dacron cuff that anchors the catheter subcutaneously and reduces infection risk.

Question 2

A patient requires vesicant chemotherapy infusion over 6 months. Which vascular access device is most appropriate?

Accepted Answer

Implanted port

Answer

An implanted port is the preferred device for long-term vesicant chemotherapy due to its low infection risk, patient comfort, and ability to withstand repeated access.

Question 3

What distinguishes a polyurethane PICC from a silicone PICC in clinical practice?

Accepted Answer

Polyurethane PICCs have higher flow rates due to thinner walls

Answer

Polyurethane catheters have thinner walls than silicone, allowing larger inner lumens relative to outer diameter, which supports higher flow rates.

Question 4

Which statement about non-tunneled central venous catheters (CVCs) is correct regarding intended duration of use?

Accepted Answer

They are intended for short-term use, typically less than 14 days

Answer

Non-tunneled CVCs are intended for short-term use (typically fewer than 14 days) due to higher infection risk without subcutaneous tunneling.

Question 5

A Groshong catheter differs from a standard tunneled catheter because it features:

Accepted Answer

A three-position slit valve at the tip

Answer

The Groshong catheter has a three-position slit valve at its tip that prevents backflow of blood and air entry, reducing clotting risk.
