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

    Answer: Tunneled cuffed hemodialysis catheter

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

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

    Answer: Implanted port

    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.

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

    Answer: Polyurethane PICCs have higher flow rates due to thinner walls

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

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

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

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

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

    Answer: A three-position slit valve at the tip

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

  6. Which catheter gauge is correctly matched to its primary intended use in vascular access?

    Answer: 20-gauge peripheral IV for most routine adult IV therapy

    A 20-gauge peripheral IV catheter is appropriate for most routine adult IV therapy, balancing adequate flow with patient comfort.

  7. An antimicrobial-impregnated CVC is indicated primarily to reduce which complication?

    Answer: Central line-associated bloodstream infection (CLABSI)

    Antimicrobial-impregnated CVCs (e.g., chlorhexidine/silver sulfadiazine or minocycline/rifampin) are used specifically to reduce CLABSI rates.
