VABC Catheter Types 2

Question 1

Which catheter type is specifically designed for long-term apheresis or hemodialysis with high flow rates?

Accepted Answer

Tesio catheter

Answer

Tesio catheters are twin single-lumen tunneled catheters designed to provide high flow rates required for hemodialysis and apheresis.

Question 2

A midline catheter is typically inserted into which vein?

Accepted Answer

Basilic or cephalic vein

Answer

Midline catheters are inserted into the basilic or cephalic veins of the upper arm with the tip terminating below the axilla.

Question 3

What distinguishes a valved PICC (such as a Groshong PICC) from a non-valved PICC?

Accepted Answer

It has a three-position valve that reduces blood reflux and air entry

Answer

Groshong-type valved PICCs have a slit valve at the tip that opens for infusion or aspiration and closes at rest, reducing blood reflux and potentially eliminating routine heparin flushes.

Question 4

Which catheter is most appropriate for a patient requiring short-term central venous access in the ICU with no tunneling needed?

Accepted Answer

Non-tunneled CVC

Answer

Non-tunneled CVCs are placed directly through the skin into a central vein and are ideal for short-term ICU access where immediate insertion is required.

Question 5

The Broviac catheter differs from the Hickman catheter primarily in which way?

Accepted Answer

Broviac has a smaller internal diameter and is used in pediatric patients

Answer

Broviac catheters have a smaller internal lumen diameter compared to Hickman catheters and are primarily designed for pediatric use.
