Read the first 7 Catheter Types flashcards as text

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

    Answer: Tesio catheter

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

  2. A midline catheter is typically inserted into which vein?

    Answer: Basilic or cephalic vein

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

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

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

    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.

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

    Answer: Non-tunneled CVC

    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.

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

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

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

  6. A patient with bilateral upper extremity DVT needs reliable IV access for 6 months of chemotherapy. Which device is most appropriate?

    Answer: Implanted port via femoral approach

    An implanted port placed via the femoral vein provides long-term reliable access when upper extremity options are excluded due to bilateral DVT.

  7. Which feature of a triple-lumen CVC allows simultaneous infusion of incompatible medications?

    Answer: Separate lumens with staggered exit ports

    Triple-lumen CVCs have separate lumens with staggered exit ports along the catheter, allowing incompatible medications to mix only in the high-flow bloodstream.
