Mixed Deck — All VABC Topics Flashcards

A patient signs consent for a midline catheter but during insertion the nurse realizes a PICC is clinically indicated. The nurse should:

Answer: Stop, explain the clinical situation, and obtain new consent for the PICC before proceeding

Consent is procedure-specific; inserting a different device than the one consented to requires new informed consent.

Which precaution is MOST important when replacing IV administration sets connected to a central venous catheter used for lipid-containing parenteral nutrition?

Answer: Replacing the tubing within 24 hours of initiating lipid-containing PN using aseptic technique

CDC and INS guidelines recommend replacing IV tubing used for lipid-containing PN or blood products within 24 hours because lipids support microbial growth more rapidly than dextrose/amino acid solutions.

Which action best reflects accurate documentation when a central line-associated bloodstream infection (CLABSI) is suspected?

Answer: Document signs/symptoms, notify provider, and record actions taken

Suspected CLABSI requires prompt documentation of clinical signs, provider notification, and all interventions in real time to support patient safety and surveillance.

Which INS-recommended practice best prevents air embolism—and simultaneously supports infection prevention—during central venous catheter cap changes?

Answer: Clamping the catheter and having the patient perform the Valsalva maneuver before disconnection

Clamping the catheter and having the patient perform Valsalva or exhale before cap changes prevents air entry and limits hub exposure time, reducing both air embolism and contamination risk.

Which clinical sign most strongly suggests superior vena cava (SVC) syndrome as a complication of a long-term central venous catheter?

Answer: Bilateral facial and upper extremity edema with venous distension

SVC syndrome causes bilateral facial and upper extremity edema plus prominent neck and chest wall venous collaterals due to obstruction of the superior vena cava.

Pinch-off syndrome is a mechanical complication specific to which type of vascular access device?

Answer: Subcutaneously implanted ports with catheters placed via the subclavian vein

Pinch-off syndrome occurs when the catheter of a subclavian-inserted port is compressed between the clavicle and first rib, causing intermittent or complete occlusion and catheter fracture risk.

A pediatric oncology patient's implanted port is accessed for chemotherapy but there is no blood return despite easy flush. Which action is CONTRAINDICATED?

Answer: Forcefully flushing with a 10 mL syringe at high pressure to clear the occlusion

Forceful flushing against resistance is contraindicated as it can rupture the catheter, dislodge a thrombus as an embolus, or cause catheter fracture.

Which statement BEST describes the relationship between Vascular Access Board Certification certification requirements and industry evolution?

Answer: Requirements evolve periodically to reflect advances in knowledge, technology, and practice standards

Certification requirements evolve to keep pace with advances in professional knowledge, technological developments, and changes in practice standards. This ensures that certified professionals remain current and competent in a changing professional landscape.

What distinguishes a Vascular Access Board Certification certified professional from a non-certified practitioner?

Answer: Certification validates competency through standardized assessment against established benchmarks

Certification provides objective validation of competency through standardized assessment. While non-certified practitioners may be skilled, certification offers verified evidence that a professional meets established benchmarks for knowledge and performance.

Which segment of the subclavian vein is most prone to pinch-off syndrome when used for long-term central venous access?

Answer: Middle third beneath the clavicle

Pinch-off syndrome occurs when the catheter is compressed between the clavicle and first rib in the middle third of the subclavian vein, causing intermittent or permanent occlusion.

Why is patient education essential for managing vascular access devices?

Answer: It ensures the patient understands device care, signs of complications, and follow-up needs, improving outcomes

Patient education is a cornerstone of effective vascular access device management. When patients understand how to care for their device, recognize early signs of complications like infection or occlusion, and know their follow-up schedule, they become active participants in their own care. This knowledge empowers them to report issues promptly and adhere to maintenance protocols, significantly reducing the risk of complications and ultimately leading to better treatment outcomes and improved quality of life.

The femoral vein becomes the external iliac vein at which anatomical landmark?

Answer: Inguinal ligament

The femoral vein passes beneath the inguinal ligament, at which point it becomes the external iliac vein.

A PICC patient has a confirmed upper extremity DVT. The catheter is still patent and functional and the patient requires continued IV therapy. What is the recommended approach per current guidelines?

Answer: Anticoagulate and remove the PICC only if it is no longer needed

Current guidelines recommend initiating anticoagulation and removing the catheter only when it is no longer needed, balancing thrombosis treatment with ongoing IV access needs.

A patient with a newly placed tunneled CVC develops fever, chills, and erythema along the tunnel tract 8 days post-insertion. Which management is MOST appropriate?

Answer: Remove the catheter and initiate systemic antibiotics

Tunnel tract infection extending more than 2 cm from the exit site requires catheter removal along with systemic antibiotic therapy.

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.

What are the common complications associated with vascular access devices?

Answer: Common complications include infection, thrombosis, occlusion, and mechanical issues like dislodgement

Vascular access devices are associated with several common complications, including infection, thrombosis (blood clot formation), occlusion (blockage of the catheter), and mechanical issues such as dislodgement or breakage. Vigilant monitoring and proper management protocols are essential to prevent, detect, and address these complications promptly, ensuring the device's functionality and patient safety.

A pharmaceutical company offers a vascular access team expensive gifts in exchange for using their catheters exclusively. Accepting these gifts would violate which principle?

Answer: Impartiality and avoidance of conflicts of interest

Accepting gifts that influence clinical decisions creates a conflict of interest and compromises the integrity of patient-centered care.

Per current INS Standards of Practice, which solution is recommended as the first-line flush for most vascular access devices?

Answer: 0.9% Normal Saline

The INS recommends 0.9% preservative-free Normal Saline as the first-line flush for most vascular access devices, reserving heparin for specific catheter types.

When securing a peripheral IV in a toddler, which method is most appropriate to prevent accidental dislodgement while allowing ongoing assessment?

Answer: Sterile transparent dressing with site visible, and a splint as needed

A transparent semipermeable membrane dressing keeps the site visible for ongoing assessment while securing the catheter, with a splint added for joint sites if needed.

What is the MOST effective way for new VABC professionals to build competency in their field?

Answer: Combining formal education, mentored practice, and ongoing professional development

Building professional competency requires a multi-faceted approach: formal education provides foundational knowledge, mentored practice develops applied skills under guidance, and ongoing professional development ensures continuous growth and currency in the field.
