  1. A non-coring Huber needle is required to access which type of vascular access device?

    Answer: Implanted port

    Huber needles have a deflected tip that cores the silicone septum of an implanted port without removing material, preserving the septum's integrity over hundreds of accesses.

  2. Which catheter is most appropriate for a neonate requiring umbilical venous access for emergency resuscitation medications?

    Answer: Umbilical venous catheter (UVC)

    An umbilical venous catheter provides rapid central venous access via the umbilical vein in neonates, making it the first-line device in neonatal resuscitation.

  3. Antimicrobial-impregnated CVCs are typically coated with which combination of agents to reduce CLABSI rates?

    Answer: Chlorhexidine and silver sulfadiazine, or minocycline and rifampin

    Evidence-based antimicrobial CVCs use either chlorhexidine/silver sulfadiazine (external surface) or minocycline/rifampin (internal and external surfaces) to reduce biofilm and CLABSI rates.

  4. What is the key hemodynamic indication that distinguishes use of a pulmonary artery catheter (Swan-Ganz) from a standard CVC?

    Answer: Direct measurement of pulmonary artery pressures and cardiac output

    A pulmonary artery catheter (Swan-Ganz) advances through the right heart into the pulmonary artery, enabling direct measurement of hemodynamic parameters unavailable with a standard CVC.

  5. Which catheter characteristic is most important when selecting a device for continuous renal replacement therapy (CRRT)?

    Answer: High flow capability with large internal lumen diameter

    CRRT requires blood flow rates of 100-300 mL/min, necessitating a large-bore catheter with a high-flow lumen to prevent circuit clotting.

  6. A patient develops catheter tip malposition into the right atrium. What is the primary clinical concern?

    Answer: Cardiac arrhythmias and potential cardiac perforation

    A catheter tip in the right atrium can irritate the myocardium, causing arrhythmias, and carries a risk of cardiac wall perforation leading to tamponade.

  7. Which catheter material softens upon contact with body temperature, reducing the risk of vessel perforation?

    Answer: Thermoplastic polyurethane

    Thermoplastic polyurethane catheters become softer and more pliable at body temperature, conforming to vessel anatomy and reducing mechanical trauma and perforation risk.
