- Gentle circular motion from outer edge inward
- Back-and-forth scrubbing motion, working outward from the insertion site
- Single wipe in one direction only
Correct answer: Friction scrub from insertion site outward with 30-second contact time
CHG requires a friction scrub moving from the insertion site outward, with at least 30 seconds of contact and full dry time to maximize antimicrobial effectiveness.
Question 54: What is the difference between a tunneled and a non-tunneled central venous catheter?
- Non-tunneled CVCs are used for long-term access
- Non-tunneled CVCs are more secure and easier to insert
- Tunneled CVCs are for long-term use and are surgically inserted under the skin (Correct answer)
- Tunneled CVCs are for short-term use only
Correct answer: Tunneled CVCs are for long-term use and are surgically inserted under the skin
The key difference lies in their insertion and intended duration of use: tunneled CVCs are surgically inserted under the skin and have a subcutaneous tunnel and cuff, which provides a barrier against infection and helps secure the catheter for long-term use. Non-tunneled CVCs are inserted directly into a central vein and are typically used for short-term access, as they carry a higher risk of infection due to the lack of a subcutaneous tunnel.
Question 55: A 5-year-old child has a midline catheter placed in the right basilic vein with the tip confirmed at the mid-upper arm. Which infusate is appropriate for this device?
- Vancomycin at standard concentration (Correct answer)
- Continuous vasopressor infusion
- Total parenteral nutrition with 20% dextrose
- 3% hypertonic saline
Correct answer: Vancomycin at standard concentration
Midline catheters are appropriate for isotonic or near-isotonic infusates such as standard-concentration antibiotics, but are not indicated for vesicants, hyperosmolar solutions, or vasopressors.
Question 56: A pharmaceutical company offers a vascular access team expensive gifts in exchange for using their catheters exclusively. Accepting these gifts would violate which principle?
- Beneficence
- Impartiality and avoidance of conflicts of interest (Correct answer)

Regular maintenance of vascular access devices is crucial for their longevity and the patient's safety. This includes routine flushing, dressing changes, and site assessment, all of which help prevent common issues like occlusion, dislodgement, and infection. By consistently adhering to maintenance protocols, healthcare providers can ensure the device remains patent and functional for its intended duration, thereby minimizing the need for reinsertion and reducing the risk of serious complications that could jeopardize patient health.
Question 66: When performing ultrasound-guided peripheral IV placement in a child, the short-axis (transverse) view is used to:
- Confirm catheter tip position in the superior vena cava
- Detect catheter-associated thrombosis after placement
- Identify vessel location, depth, and surrounding structures during needle approach (Correct answer)
- Measure catheter-to-vein ratio in real time
Correct answer: Identify vessel location, depth, and surrounding structures during needle approach
The short-axis view provides a cross-sectional image that allows the clinician to identify vessel location, assess surrounding structures, and guide needle placement.
Question 67: A vascular access nurse is inserting a PICC in a patient with a known allergy to chlorhexidine. Which alternative skin antiseptic should be used?
- Benzalkonium chloride 0.1%
- Hydrogen peroxide 3%
- Sterile water with vigorous mechanical scrubbing
- Povidone-iodine 10% allowed to dry completely (Correct answer)
Correct answer: Povidone-iodine 10% allowed to dry completely
Povidone-iodine is the recommended alternative skin antiseptic for patients with chlorhexidine allergy, provided adequate contact time and drying are observed.
Question 68: Which intraosseous insertion site is preferred in children over 6 years of age when tibial access is unavailable?
- Iliac crest
- Distal femur (Correct answer)
- Sternum
- Calcaneus
Correct answer: Distal femur
The distal femur is an alternative IO insertion site in older children and adults when the proximal tibia is not accessible.
Question 69: Which professional attribute is most valued in documentation within the VABC field?
- Avoiding challenging situations
- Working in isolation
- Accountability and commitment to standards (Correct answer)
- Prioritizing personal convenience
Correct answer: Accountability and commitment to 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.
Question 72: The femoral vein becomes the external iliac vein at which anatomical landmark?
- Pubic symphysis
- Inguinal ligament (Correct answer)
- Iliac crest
- Obturator foramen
Correct answer: Inguinal ligament
The femoral vein passes beneath the inguinal ligament, at which point it becomes the external iliac vein.
Question 73: Which dressing type is preferred for CVAD insertion sites in adults without excessive perspiration or bleeding?
- Transparent semipermeable membrane (TSM) dressing (Correct answer)
- Non-occlusive gauze dressing
- Gauze and tape
- Hydrocolloid dressing
Correct answer: Transparent semipermeable membrane (TSM) dressing
TSM dressings allow continuous visualization of the insertion site, reduce infection risk, and require less frequent changes than gauze dressings.
Question 74: Which personal protective equipment (PPE) principle applies to ALL VABC certified professionals regardless of their specific role?
- PPE is optional if experienced in the field
- PPE must be properly fitted, maintained, and replaced as needed (Correct answer)
- PPE is only necessary during formal inspections
- Any PPE will provide adequate protection
Correct answer: PPE must be properly fitted, maintained, and replaced as needed
Regardless of experience level or specific role, PPE must be properly fitted to the individual, regularly maintained in good condition, and replaced when worn or damaged. Improperly fitted or degraded PPE can provide a false sense of security.
Question 75: When treating catheter-related thrombosis in an upper extremity PICC, what is the preferred initial anticoagulation agent according to current guidelines?
- Thrombolytic therapy with alteplase
- Low molecular weight heparin (LMWH) or direct oral anticoagulant (DOAC) (Correct answer)
- Unfractionated heparin IV infusion
- Warfarin initiated immediately
Correct answer: Low molecular weight heparin (LMWH) or direct oral anticoagulant (DOAC)
Current guidelines recommend LMWH or DOACs as first-line anticoagulation for upper extremity DVT related to vascular access catheters.
Question 76: A patient with an implanted port reports inability to withdraw blood but medications infuse freely. The FIRST intervention should be:
- Reposition the patient and attempt aspiration with a 10 mL syringe using gentle pressure (Correct answer)
- Order a CT scan to confirm port position
- Remove and replace the port immediately
- Administer alteplase immediately without further assessment
Correct answer: Reposition the patient and attempt aspiration with a 10 mL syringe using gentle pressure
Positional fibrin flap or tip malposition can cause withdrawal occlusion; repositioning (raising arms, Valsalva, changing position) often resolves the issue before pharmacological intervention.
Question 77: What distinguishes a Vascular Access Board Certification certified professional from a non-certified practitioner?
- There is no meaningful difference in competency
- Certification validates competency through standardized assessment against established benchmarks (Correct answer)
- Certified professionals always have more years of experience
- Certified professionals exclusively work in larger organizations
Correct 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.
Question 78: Why is patient education important during the assessment phase for vascular access device insertion?
- It is important only after the procedure is completed
- It helps the patient understand the procedure, risks, and proper device care, reducing complications (Correct answer)
- It only helps the patient prepare emotionally for the procedure
- It is unnecessary for the patient to be educated before the procedure
Correct answer: It helps the patient understand the procedure, risks, and proper device care, reducing complications
Patient education during the assessment phase for vascular access device insertion is vital because it helps the patient understand the procedure, potential risks, and proper device care. An informed patient is more likely to cooperate during insertion, adhere to post-procedure instructions, and promptly report any concerns, thereby reducing the risk of complications and improving overall outcomes and satisfaction.
Question 79: Under CDC guidelines, routine replacement of central venous catheters over a guidewire is indicated in which situation?
- Every 72 hours to prevent biofilm formation
- Every 7 days as a scheduled maintenance measure
- Whenever the dressing becomes soiled or non-adherent
- When catheter malfunction occurs in the absence of infection (Correct answer)
Correct answer: When catheter malfunction occurs in the absence of infection
Guidewire exchange is appropriate when the existing catheter is malfunctioning but there is no evidence of infection; it should not be used as a routine prevention strategy.
Question 80: A patient with congestive heart failure (CHF) and an ejection fraction of 20% requires central venous access for inotropic therapy. During assessment, the nurse notes prominent jugular venous distension (JVD) to the jaw. This finding indicates:
- Correct catheter positioning if a CVC is already in place
- Markedly elevated central venous pressure requiring physician notification before proceeding (Correct answer)
- Normal finding in a patient with CHF receiving diuretics
- The internal jugular vein will be easily cannulated due to distension
Correct answer: Markedly elevated central venous pressure requiring physician notification before proceeding
JVD to the jaw reflects severely elevated CVP and hemodynamic instability, which must be communicated to the physician before invasive procedures.
Question 81: During a dressing change on a PICC, the nurse notices the external catheter length has increased by 3 cm since the last assessment. This finding MOST likely indicates:
- The patient's arm has grown since insertion
- The catheter has migrated outward and the tip may no longer be in the SVC (Correct answer)
- The original measurement was documented incorrectly
- Normal catheter elongation from IV fluid pressure
Correct answer: The catheter has migrated outward and the tip may no longer be in the SVC
An increase in external catheter length indicates the catheter has migrated outward, meaning the tip may have moved from its original optimal position and requires radiographic confirmation.
Question 82: A patient reports a PICC line was placed 3 days ago but now has pain and swelling along the upper arm. Which assessment finding would most strongly suggest catheter-related thrombosis?
- Pitting edema of the ipsilateral arm with visible collateral veins (Correct answer)
- Fever above 38.5°C
- Decreased blood pressure in the affected arm
- Redness at the insertion site
Correct answer: Pitting edema of the ipsilateral arm with visible collateral veins
Pitting edema with visible collateral veins indicates venous outflow obstruction consistent with upper extremity DVT.
Question 83: Which of the following best describes the concept of 'biofilm' as it relates to vascular access infection risk?
- An inflammatory reaction around the catheter tip in the vasculature
- A layer of fibrin clot that occludes the catheter lumen
- A protective coating of glycocalyx-embedded microorganisms on the catheter surface (Correct answer)
- A chemical film left by incompatible IV flush solutions
Correct answer: A protective coating of glycocalyx-embedded microorganisms on the catheter surface
Biofilm is a structured community of microorganisms encased in a self-produced matrix that adheres to catheter surfaces and is highly resistant to antibiotics and host defenses.
Question 84: Which deep vein thrombosis location carries the highest risk of pulmonary embolism due to clot size and proximity to central circulation?
- Tibial veins
- Iliofemoral segment (Correct answer)
- Superficial femoral vein
- Popliteal vein
Correct answer: Iliofemoral segment
Iliofemoral DVT carries the highest risk of pulmonary embolism because clots in this proximal, large-diameter segment can dislodge and travel to the pulmonary circulation.
Question 85: After alteplase instillation for a thrombotic occlusion fails to restore patency, the NEXT appropriate step is:
- Repeat the alteplase dwell for a second instillation up to 2 hours, then consider imaging (Correct answer)
- Administer systemic thrombolytics intravenously
- Remove the catheter immediately
- Repeat alteplase with a higher concentration (2 mg/mL)
Correct answer: Repeat the alteplase dwell for a second instillation up to 2 hours, then consider imaging
If the first alteplase dwell does not restore patency, a second instillation is appropriate; if both fail, imaging studies are indicated to evaluate for fibrin sheath or other structural causes.
Question 86: When performing a central line dressing change, which action is most important for infection prevention?
- Flushing the catheter with normal saline before removing the old dressing
- Changing the dressing every 24 hours regardless of condition
- Using sterile gloves and a sterile field throughout the procedure (Correct answer)
- Applying povidone-iodine ointment to the insertion site routinely
Correct answer: Using sterile gloves and a sterile field throughout the procedure
Maintaining sterile technique with sterile gloves and a sterile field during dressing changes is fundamental to preventing catheter site contamination.
Question 87: When conducting a risk assessment for VABC operations, which factor should receive the HIGHEST priority?
- Time required for safety training
- Probability and severity of potential harm (Correct answer)
- Cost of implementing safety measures
- Convenience for daily operations
Correct answer: Probability and severity of potential harm
The probability and severity of potential harm are the primary factors in risk assessment. While cost and convenience are considerations, they should never override the assessment of how likely an incident is and how severe its consequences could be.
Question 88: The azygos vein drains into which central venous structure at approximately the level of T4?
- Left brachiocephalic vein
- Right atrium directly
- Superior vena cava (Correct answer)
- Inferior vena cava
Correct answer: Superior vena cava
The azygos vein arches over the right main bronchus at the T4 level and empties into the posterior aspect of the superior vena cava.
Question 89: Which maneuver can increase the diameter of the internal jugular vein to facilitate ultrasound-guided cannulation?
- Sitting the patient upright at 90 degrees
- Asking the patient to perform a Valsalva maneuver only during needle insertion
- Applying firm probe pressure over the vessel
- Placing the patient in Trendelenburg position (Correct answer)
Correct answer: Placing the patient in Trendelenburg position
Trendelenburg (head-down) positioning increases venous return and distends the internal jugular vein, making it a larger and easier target.
Question 90: For implanted venous ports, which dressing type and change frequency is recommended by INS when the site is well-healed and accessed with a non-coring needle?
- Sterile gauze changed every 24 hours while the needle is in place
- Dry gauze changed every 48 hours with povidone-iodine reapplication
- No dressing required once the site is fully healed and the needle is secured
- Transparent semipermeable membrane changed every 7 days or sooner if integrity is compromised (Correct answer)
Correct answer: Transparent semipermeable membrane changed every 7 days or sooner if integrity is compromised
INS recommends a TSM dressing changed every 7 days (or sooner if non-intact) over an accessed implanted port needle to maintain a sterile barrier at the insertion site.
Question 91: Which precaution is MOST important when replacing IV administration sets connected to a central venous catheter used for lipid-containing parenteral nutrition?
- Replacing the tubing every 96 hours using clean technique
- Replacing the tubing every 72 hours regardless of PN composition
- Replacing the tubing only when visibly soiled or when the PN bag is changed
- Replacing the tubing within 24 hours of initiating lipid-containing PN using aseptic technique (Correct answer)
Correct 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.
Question 92: Which drug administration technique involves injecting a medication directly into an IV access port over a short period (typically 1–5 minutes)?
- IV bolus (IV push) (Correct answer)
- Patient-controlled analgesia (PCA)
- Intermittent infusion via piggyback
- Continuous infusion
Correct answer: IV bolus (IV push)
IV bolus (IV push) delivers a concentrated dose of medication directly into the IV port over 1–5 minutes, achieving rapid peak plasma levels.
Question 93: What is the primary venous drainage pathway from the upper extremity back to the heart in order?
- Ulnar → basilic → axillary → brachiocephalic → SVC
- Radial → brachial → subclavian → SVC
- Basilic → brachial → axillary → subclavian → brachiocephalic → SVC (Correct answer)
- Cephalic → axillary → subclavian → brachiocephalic → SVC
Correct answer: Basilic → brachial → axillary → subclavian → brachiocephalic → SVC
The basilic vein drains into the brachial vein, which joins the axillary vein, then the subclavian vein, then the brachiocephalic vein, and finally the superior vena cava.
Question 94: A patient with a BMI of 42 requires peripheral IV access. Which assessment approach is BEST to locate a suitable vein?
- Use a blood pressure cuff as a tourniquet and rely on visual identification
- Palpate deeply along the antecubital fossa and forearm, using ultrasound if no vein is found (Correct answer)
- Attempt multiple venipunctures systematically until a vein is accessed
- Immediately request a central line due to obesity
Correct answer: Palpate deeply along the antecubital fossa and forearm, using ultrasound if no vein is found
Deep palpation combined with ultrasound guidance is the evidence-based approach for patients with difficult venous access due to obesity.
Question 95: A pediatric patient's parents refuse a medically necessary central line. Which ethical framework best guides the next step?
- Accept the refusal without further discussion
- Override the parents immediately and proceed
- Discharge the child at parental request
- Engage ethics consultation to balance parental rights against the child's best interests (Correct answer)
Correct answer: Engage ethics consultation to balance parental rights against the child's best interests
When parental refusal conflicts with a child's medical welfare, an ethics consultation helps navigate competing values within legal and institutional frameworks.
Question 96: Which foundational principle is MOST important for success in the Vascular Access Board Certification profession?
- Maintaining the minimum requirements for certification
- Specializing in only one narrow area of practice
- Maximizing financial returns on every engagement
- Commitment to continuous learning, ethical practice, and quality outcomes (Correct answer)
Correct answer: Commitment to continuous learning, ethical practice, and quality outcomes
Success in any professional field requires a commitment to continuous learning to stay current, ethical practice to maintain trust and integrity, and a focus on quality outcomes that serve stakeholders and the public interest.
Question 97: A patient with a tunneled hemodialysis catheter is prescribed an antibiotic lock solution. What is the PRIMARY goal of this therapy?
- To anticoagulate the catheter between dialysis sessions
- To flush fibrin sheaths from the catheter tip
- To prevent thrombosis by maintaining catheter patency
- To sterilize the catheter lumen and eradicate intraluminal biofilm without catheter removal (Correct answer)
Correct answer: To sterilize the catheter lumen and eradicate intraluminal biofilm without catheter removal
Antibiotic lock therapy delivers high-concentration antibiotics directly into the catheter lumen to eradicate biofilm-associated organisms, potentially allowing catheter salvage.
Question 98: What is the recommended frequency range for linear transducers used in peripheral vascular access ultrasound guidance?
- 5–10 MHz
- 1–5 MHz
- 7–15 MHz (Correct answer)
- 20–30 MHz
Correct answer: 7–15 MHz
Linear transducers in the 7–15 MHz range provide optimal resolution for superficial vascular structures during peripheral vascular access.
Question 99: Which patient population is at HIGHEST risk for developing a catheter-related fungal bloodstream infection?
- Pediatric patients with short-term peripheral IVs
- Ambulatory patients with implanted ports accessed monthly
- Immunocompromised patients on broad-spectrum antibiotics receiving total parenteral nutrition (Correct answer)
- Elderly patients with diabetes receiving oral antibiotics
Correct answer: Immunocompromised patients on broad-spectrum antibiotics receiving total parenteral nutrition
Immunocompromised patients receiving broad-spectrum antibiotics and TPN are at highest risk for Candida CRBSI due to disrupted normal flora, impaired immunity, and a high-nutrient intraluminal environment.
Question 100: When documenting a PICC insertion, which anatomical landmark must be recorded to confirm tip position?
- Cavoatrial junction or lower third of superior vena cava (Correct answer)
- Subclavian vein junction
- Antecubital fossa entry site
- Right atrium
Correct answer: Cavoatrial junction or lower third of superior vena cava
PICC tip position must be documented as residing at the cavoatrial junction or the lower third of the SVC for safe central venous infusion.
