Vascular Access Board Certified (VA-BC™) Exam — Questions and Answers

Question 1: A nurse makes two unsuccessful attempts to place a peripheral IV in a patient with difficult venous access. What is the best next step?

Escalate to a clinician skilled in ultrasound-guided insertion (Correct answer)
Place the catheter in a lower-extremity vein
Try a third time with a smaller catheter
Apply a tourniquet for 5 minutes and try again

Correct answer: Escalate to a clinician skilled in ultrasound-guided insertion

INS limits each clinician to 2 attempts and recommends escalating to a more skilled clinician or using visualization technology.

Question 2: When conducting a risk assessment for VA-BC operations, which factor should receive the HIGHEST priority?

Probability and severity of potential harm (Correct answer)
Convenience for daily operations
Cost of implementing safety measures
Time required for safety training

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 3: During a modified Seldinger PICC insertion, the guidewire has been threaded through the access needle. What is the next step?

Inject saline through the needle to confirm placement
Remove the guidewire and thread the catheter through the needle
Remove the needle while holding the wire, then advance the microintroducer-dilator over the wire (Correct answer)
Advance the catheter directly over the needle

Correct answer: Remove the needle while holding the wire, then advance the microintroducer-dilator over the wire

In MST the needle is removed over the wire, a small skin nick is often made, and the introducer-dilator is advanced over the guidewire.

Question 4: The right lymphatic duct drains lymph from which region of the body?

Right and left lower extremities only
Entire left side of the body
Entire lower body and left upper body
Right upper quadrant of the body (Correct answer)

Correct answer: Right upper quadrant of the body

The right lymphatic duct drains only the right upper quadrant (right arm, right side of head/neck, right thorax), while the thoracic duct drains everywhere else.

Question 5: A nurse uses ultrasound guidance for peripheral IV placement in a 7-year-old with difficult access. In the transverse (short-axis) view, the vein appears as:

A hyperechoic (bright white) circular structure
An elongated tubular structure running along the screen
A pulsating bright oval structure
A circular dark (anechoic) structure that compresses with pressure (Correct answer)

Correct answer: A circular dark (anechoic) structure that compresses with pressure

In the transverse ultrasound view, veins appear as circular, anechoic (dark) structures that collapse easily with probe pressure, distinguishing them from arteries.

Question 6: Which regulatory requirement is UNIVERSAL across all Vascular Access Nurse Certification practice settings?

Limiting services to local jurisdictions only
Using specific proprietary software systems
Maintaining current certification and meeting continuing education requirements (Correct answer)
Working exclusively during business hours

Correct answer: Maintaining current certification and meeting continuing education requirements

Maintaining current certification and meeting continuing education requirements is a universal regulatory requirement. Regardless of practice setting, professionals must keep their credentials current and demonstrate ongoing competency through continuing education.

Question 7: Which assessment method provides the MOST reliable data for VA-BC professionals making critical decisions?

Social media reviews and testimonials
Single-source data from one stakeholder
Standardized tools combined with professional observation (Correct answer)
Informal verbal feedback alone

Correct answer: Standardized tools combined with professional observation

Combining standardized assessment tools with professional observation provides the most reliable and comprehensive data. Standardized tools ensure consistency and validity, while professional observation captures nuances that tools might miss.

Question 8: For peripheral IV catheters, when should removal occur according to current evidence-based standards?

Only when the infusion therapy is complete
When clinically indicated or no longer needed, rather than on a routine fixed schedule (Correct answer)
Every 72 hours regardless of condition
Every 24 hours

Correct answer: When clinically indicated or no longer needed, rather than on a routine fixed schedule

Clinically indicated replacement is supported over routine time-based removal.

Question 9: A vascular access nurse serves on the hospital QI committee and is asked to present on infection prevention. Which evidence level MOST strongly supports a practice recommendation?

Manufacturer's product literature
Expert opinion from a senior nurse
Systematic review or meta-analysis of randomized controlled trials (Correct answer)
A single case report from another institution

Correct answer: Systematic review or meta-analysis of randomized controlled trials

Systematic reviews and meta-analyses of RCTs represent the highest level of evidence in evidence-based practice hierarchies.

Question 10: A patient with active pulmonary tuberculosis needs a PICC. Which respiratory protection should the inserter wear?

Standard surgical mask
Fit-tested N95 respirator or higher (Correct answer)
No mask is needed with sterile gown
Face shield only

Correct answer: Fit-tested N95 respirator or higher

Airborne precautions for TB require a fit-tested N95 or higher-level respirator.

Question 11: What is the BEST way for a Vascular Access Nurse Certification professional to stay current with regulatory changes?

Depend on colleagues to share updates informally
Check regulations only during certification renewal
Rely solely on employer notifications
Actively monitor regulatory bodies, attend continuing education, and participate in professional associations (Correct answer)

Correct answer: Actively monitor regulatory bodies, attend continuing education, and participate in professional associations

Staying current requires a multi-faceted approach: monitoring regulatory agencies directly, attending relevant continuing education programs, and participating in professional associations that disseminate regulatory updates.

Question 12: A caregiver reports that the external length of the PICC appears longer than the measurement recorded at discharge. What should the caregiver be taught to do?

Trim the excess catheter
Push the catheter back in to the original length
Continue infusions as usual
Not push the catheter in, secure it, and contact the healthcare provider (Correct answer)

Correct answer: Not push the catheter in, secure it, and contact the healthcare provider

Never re-advance a migrated catheter because it introduces contamination; the line must be assessed for tip position before use.

Question 13: When inserting a PICC, the tip should be confirmed at which anatomical location?

Subclavian vein
Superior vena cava/right atrial junction (Correct answer)
Axillary vein
Internal jugular vein

Correct answer: Superior vena cava/right atrial junction

PICC tip placement at the cavoatrial junction (SVC/RA junction) is the standard for central venous catheter placement.

Question 14: When selecting a vein for a midline catheter, the preferred insertion site is:

External jugular vein
Femoral vein
Antecubital fossa veins (basilic, cephalic, or median cubital) (Correct answer)
Dorsal hand veins

Correct answer: Antecubital fossa veins (basilic, cephalic, or median cubital)

Midline catheters are inserted in the antecubital fossa and advance 8–20 cm, terminating below the axilla.

Question 15: For CLABSI surveillance purposes, which documentation element links a bloodstream infection to a specific central line?

The physician's name who ordered the line
Catheter type, insertion date, insertion site, and days in place at time of infection (Correct answer)
The infusion rate at the time infection was suspected
Patient's insurance information

Correct answer: Catheter type, insertion date, insertion site, and days in place at time of infection

NHSN CLABSI definitions require documentation of catheter characteristics and dwell time to attribute a BSI to a specific central line and trigger appropriate surveillance.

Question 16: Venous capacitance refers to the ability of veins to:

Generate high pressure to return blood to the heart
Constrict rapidly in response to hemorrhage
Deliver oxygen directly to surrounding tissues
Store large volumes of blood with minimal pressure change (Correct answer)

Correct answer: Store large volumes of blood with minimal pressure change

Veins are highly compliant (capacitance vessels) and can hold up to 70% of total blood volume with little increase in pressure due to their thin, distensible walls.

Question 17: A nurse charts a peripheral IV insertion she did not perform because the inserting colleague was busy. This action is best described as:

Acceptable delegation
A late entry
Co-signature
Falsification of the medical record (Correct answer)

Correct answer: Falsification of the medical record

Documenting care you did not personally perform or witness as your own is falsification and exposes the nurse to legal and licensure action.

Question 18: What is the BEST way for a Vascular Access Nurse Certification professional to stay current with regulatory changes?

Check regulations only during certification renewal
Depend on colleagues to share updates informally
Actively monitor regulatory bodies, attend continuing education, and participate in professional associations (Correct answer)
Rely solely on employer notifications

Correct answer: Actively monitor regulatory bodies, attend continuing education, and participate in professional associations

Question 19: What does validity mean when selecting an assessment tool for VA-BC certification purposes?

The tool is widely used
The tool is easy to administer
The tool is inexpensive
The tool measures what it claims to measure (Correct answer)

Correct answer: The tool measures what it claims to measure

Validity indicates that an assessment tool accurately measures the construct or ability it was designed to measure.

Question 20: An implanted port that is not in active use should be accessed and flushed at which interval to maintain patency?

Every 3 months (Correct answer)
Every 4 weeks
Every 24 hours
Every 7 days

Correct answer: Every 3 months

INS standards recommend flushing implanted ports every 3 months when not in use to maintain patency and prevent occlusion.

Question 21: In Vascular Access Nurse Certification, what is the PRIMARY purpose of conducting an initial assessment?

To demonstrate the assessor's expertise
To generate documentation for billing purposes
To establish a baseline and identify needs for appropriate action (Correct answer)
To fulfill administrative paperwork requirements

Correct answer: To establish a baseline and identify needs for appropriate action

The initial assessment establishes a baseline of current conditions and identifies specific needs. This foundational information guides all subsequent decisions, planning, and interventions.

Question 22: A patient's central line dressing becomes visibly soiled 2 days after placement. When should the dressing be changed?

At the next scheduled change (day 7)
After notifying the physician
Immediately (Correct answer)
Within the next 4 hours

Correct answer: Immediately

Soiled, wet, or loosened dressings must be changed immediately to prevent bacterial migration along the catheter tract.

Question 23: Which gauge needle is preferred for a rapid blood transfusion in an emergency adult patient?

22 gauge
24 gauge
20 gauge
18 gauge (Correct answer)

Correct answer: 18 gauge

An 18-gauge catheter allows rapid infusion rates needed for emergency transfusions without hemolysis risk.

Question 24: What documentation is MOST critical to maintain for safety compliance in the Vascular Access Nurse Certification field?

Annual revenue reports
Client marketing preferences
Employee vacation schedules
Incident reports, training records, and inspection logs (Correct answer)

Correct answer: Incident reports, training records, and inspection logs

Incident reports, training records, and inspection logs are essential safety documentation. They demonstrate compliance with safety regulations, track training completion, and provide evidence of systematic hazard management.

Question 25: Under USP <800>, which equipment is recommended when administering hazardous antineoplastic drugs?

Standard IV set with a vented spike
Sterile gloves only
Closed-system drug-transfer device and two pairs of chemotherapy-tested gloves (Correct answer)
Single pair of latex gloves and surgical mask

Correct answer: Closed-system drug-transfer device and two pairs of chemotherapy-tested gloves

USP <800> requires closed-system transfer devices for administration when the dosage form allows, and double chemotherapy gloves.

Question 26: In the context of central venous catheter QI, which metric is a PROCESS measure rather than an outcome measure?

Average length of hospital stay
Rate of chlorhexidine skin prep compliance during insertion (Correct answer)
CLABSI rate per 1,000 catheter-days
30-day catheter-related mortality

Correct answer: Rate of chlorhexidine skin prep compliance during insertion

Compliance with chlorhexidine prep is a process measure reflecting adherence to a specific care step, not the end outcome.

Question 27: When administering alteplase (tPA) for a thrombotic catheter occlusion, what is the standard dwell time recommended before attempting aspiration?

4–6 hours
5–10 minutes
30 minutes
30–120 minutes (Correct answer)

Correct answer: 30–120 minutes

Standard protocols recommend a dwell time of 30–120 minutes (commonly 30 minutes with a repeat dwell if needed) to allow alteplase to dissolve the fibrin clot.

Question 28: With intracavitary ECG tip confirmation, which P-wave change shows the catheter tip has gone past the cavoatrial junction into the right atrium?

A biphasic P wave with an initial negative deflection (Correct answer)
The tallest positive P wave
A flat P wave
A widened QRS complex

Correct answer: A biphasic P wave with an initial negative deflection

The peak P wave marks the cavoatrial junction, and a negative or biphasic deflection means the tip is in the right atrium and should be pulled back.

Question 29: Which QI framework focuses on defining defects, measuring current performance, analyzing causes, improving, and then controlling the process?

PDSA
RCA
DMAIC (Correct answer)
Lean

Correct answer: DMAIC

DMAIC (Define, Measure, Analyze, Improve, Control) is the Six Sigma framework used for structured process improvement.

Question 30: In Vascular Access Nurse Certification practice, what is the FIRST step when a safety hazard is identified in the workplace?

Document it for the next safety audit
Immediately secure the area and report the hazard (Correct answer)
Wait for a supervisor to notice the issue
Continue working and report at end of shift

Correct answer: Immediately secure the area and report the hazard

When a safety hazard is identified, the immediate priority is to secure the area to prevent injury and report the hazard through proper channels. Delaying action increases the risk of incidents.

Question 31: During out-of-plane (short-axis) ultrasound-guided cannulation, how does the needle tip usually appear?

As a pulsating gray shadow
As a bright hyperechoic dot on the screen (Correct answer)
As a full-length bright line
As a dark anechoic circle

Correct answer: As a bright hyperechoic dot on the screen

In short axis the beam crosses the needle, which shows up as a hyperechoic dot, and you must walk the probe forward to keep the tip in view.

Question 32: Venous stasis, endothelial injury, and hypercoagulability are collectively known as:

Frank-Starling Mechanism
Starling's Law
Laplace's Law
Virchow's Triad (Correct answer)

Correct answer: Virchow's Triad

Virchow's Triad describes the three major risk factors for thrombosis: venous stasis, endothelial damage, and a hypercoagulable state.

Question 33: An administration set used to infuse propofol should be changed how often?

Every 7 days
Every 96 hours
Every 24 hours regardless of vial
Every 6 or 12 hours per manufacturer, or when the vial is changed (Correct answer)

Correct answer: Every 6 or 12 hours per manufacturer, or when the vial is changed

Propofol supports rapid microbial growth, so tubing is changed every 6 to 12 hours depending on the manufacturer.

Question 34: After removing a nontunneled CVC, what dressing should be applied to the exit site?

Air-occlusive dressing left in place for at least 24 hours (Correct answer)
Dry gauze removed after 1 hour
No dressing; leave open to air
Adhesive bandage strip

Correct answer: Air-occlusive dressing left in place for at least 24 hours

An air-occlusive dressing for at least 24 hours prevents air entry through the skin-to-vein tract until it epithelializes.

Question 35: Which of the following is the MOST effective method to prevent needleless connector contamination during routine line maintenance?

Keeping a sterile cap on the connector at all times between uses
Changing connectors every 24 hours on lipid-based infusions
Vigorous mechanical scrub of the connector surface for ≥5 seconds with CHG/alcohol prior to each access (Correct answer)
Replacing connectors with every dressing change

Correct answer: Vigorous mechanical scrub of the connector surface for ≥5 seconds with CHG/alcohol prior to each access

Vigorous mechanical scrub ('scrub the hub') with CHG/alcohol disinfectant for ≥5 seconds followed by drying is the standard practice to decontaminate needleless connectors before access.

Question 36: While removing a PICC, the nurse meets resistance. What is the most appropriate first action?

Stop, do not apply force, and use measures such as warm compress, repositioning, and patient relaxation before trying again (Correct answer)
Cut the catheter at the skin and leave the remainder
Pull with steady increased force until the catheter releases
Flush forcefully with a 3 mL syringe to free the catheter

Correct answer: Stop, do not apply force, and use measures such as warm compress, repositioning, and patient relaxation before trying again

Resistance often reflects venospasm; forcing removal risks catheter fracture and embolism.

Question 37: A QI initiative successfully reduces CLABSI rates from 2.1 to 0.7 per 1,000 catheter-days. Which statistical test would BEST confirm this is a significant improvement and not random variation?

Reporting the difference verbally at a staff meeting
Repeating the measurement at a different hospital
A visual trend on a run chart showing sustained shift below median
Comparing the two rates using a chi-square or statistical process control analysis (Correct answer)

Correct answer: Comparing the two rates using a chi-square or statistical process control analysis

Statistical analysis such as chi-square testing or SPC methods determines whether the improvement exceeds what would be expected by chance.

Question 38: In aseptic non-touch technique (ANTT), what are 'key-parts'?

The nurse's hands after hand hygiene
Parts of equipment that, if contaminated, could transmit pathogens to the patient (Correct answer)
Any part of the IV pole
The outer packaging of supplies

Correct answer: Parts of equipment that, if contaminated, could transmit pathogens to the patient

Key-parts such as syringe tips and connector hubs must never be touched and are protected throughout the procedure.

Question 39: Which practice is recommended to reduce the risk of CLABSI in ICU patients aged 2 months and older?

Daily bathing with chlorhexidine gluconate (Correct answer)
Scheduled CVC replacement every 7 days
Routine guidewire exchange every 72 hours
Routine topical antibiotic ointment at the insertion site

Correct answer: Daily bathing with chlorhexidine gluconate

Daily CHG bathing reduces skin bioburden and CLABSI, while scheduled replacement and antibiotic ointments are not recommended.

Question 40: Which vein characteristic found on ultrasound assessment would MOST indicate suitability for PICC insertion?

Vein collapses completely with light probe pressure
Vein is compressible, anechoic, and measures at least 4 mm in diameter (Correct answer)
Vein is located within 1 cm of the brachial artery
Vein shows increased echogenicity (bright appearance)

Correct answer: Vein is compressible, anechoic, and measures at least 4 mm in diameter

A compressible, anechoic (fluid-filled) vein of at least 4 mm diameter is considered ideal for PICC insertion via ultrasound guidance.

Question 41: During ultrasound-guided PICC insertion, the 'dynamic needle tip positioning' (DNTP) technique aims to:

Measure vein diameter in real time
Confirm tip position at the cavoatrial junction
Continuously visualize the needle tip throughout vessel entry (Correct answer)
Monitor catheter tip ECG signal

Correct answer: Continuously visualize the needle tip throughout vessel entry

DNTP keeps the needle tip continuously in view on ultrasound during advancement, reducing risk of posterior wall puncture.

Question 42: A patient becomes suddenly short of breath with chest pain while a CVAD cap is disconnected, and you suspect air embolism. How should you position the patient?

High Fowler's, sitting upright
Prone with legs elevated
On the left side with the head lowered (Trendelenburg) if not contraindicated (Correct answer)
On the right side with the head raised

Correct answer: On the left side with the head lowered (Trendelenburg) if not contraindicated

Left side, head down helps trap air in the right atrium and away from the pulmonary outflow tract.

Question 43: A hospital implements daily catheter necessity reviews. Which outcome is this intervention MOST directly designed to prevent?

Catheter-related bloodstream infections due to hub contamination
Unnecessary catheter dwell time and associated infection risk (Correct answer)
Incorrect tip placement of central venous catheters
Phlebitis from peripheral IV insertion

Correct answer: Unnecessary catheter dwell time and associated infection risk

Daily necessity reviews prompt timely removal of catheters no longer clinically indicated, directly reducing dwell time and infection risk.

Question 44: Which item is part of maximal sterile barrier precautions for CVC and PICC insertion?

Cap, mask, sterile gown, sterile gloves, and full-body sterile drape (Correct answer)
Clean gloves and mask
Sterile gloves and small fenestrated drape only
Sterile gown and clean gloves

Correct answer: Cap, mask, sterile gown, sterile gloves, and full-body sterile drape

Maximal sterile barrier precautions include cap, mask, sterile gown, sterile gloves, and a large sterile drape covering the patient.

Question 45: Per INS standards, how frequently should IV administration sets used for lipid-containing solutions be changed?

Every 24 hours (Correct answer)
Every 12 hours
Every 72 hours
Every 48 hours

Correct answer: Every 24 hours

Administration sets used for lipid-containing solutions must be changed every 24 hours due to the increased risk of microbial growth in lipid emulsions.

Question 46: Which federal law protects the privacy of a patient's vascular access records and limits disclosure of protected health information?

EMTALA
HIPAA (Correct answer)
The Patient Self-Determination Act
OSHA Bloodborne Pathogens Standard

Correct answer: HIPAA

HIPAA's Privacy Rule governs use and disclosure of protected health information, including vascular access documentation.

Question 47: According to current INS standards, peripheral IV catheters should be replaced based on which primary criterion?

Automatically every 96 hours regardless of status
Automatically every 24 hours
Automatically every 48 hours
Clinical indication such as signs of complication, not on a routine schedule (Correct answer)

Correct answer: Clinical indication such as signs of complication, not on a routine schedule

Current INS Infusion Therapy Standards of Practice recommend replacing peripheral IV catheters based on clinical indication (e.g., phlebitis, infiltration) rather than a routine time-based schedule.

Question 48: Current INS guidance recommends a catheter-to-vein ratio of no more than what percentage to lower the risk of thrombosis?

65%
80%
45% (Correct answer)
25%

Correct answer: 45%

INS recommends a catheter-to-vein ratio of 45% or less, and less is better, to reduce catheter-related thrombosis.

Question 49: The vena cava returns blood to which part of the heart?

Right ventricle
Left atrium
Left ventricle (Correct answer)
Right atrium

Correct answer: Left ventricle

The vena cava, consisting of the superior and inferior vena cava, collects deoxygenated blood from the body and returns it to the heart. Specifically, this blood enters the right atrium, which then pumps it into the right ventricle before it goes to the lungs for oxygenation. The left ventricle, conversely, pumps oxygenated blood to the rest of the body.

Question 50: Which vessel carries oxygenated blood from the heart to the body?

Aorta (Correct answer)
Capillary
Vena cava
Vein

Correct answer: Aorta

The aorta is the largest artery in the body, originating from the left ventricle of the heart. Its primary function is to distribute oxygenated blood from the heart to the systemic circulation, supplying all parts of the body except the lungs.

Question 51: In a pediatric patient with a tunneled CVC, the nurse notes the cuff is visible outside the exit site. This finding indicates:

Normal catheter positioning for this device type
The cuff has dissolved and the catheter should be removed immediately
Catheter migration that requires provider notification and evaluation (Correct answer)
No concern as long as the catheter flushes freely

Correct answer: Catheter migration that requires provider notification and evaluation

A visible cuff means the catheter has migrated outward; the provider must be notified because the cuff no longer provides the antibacterial and anchoring barrier it is designed to create.

Question 52: What is used to secure the catheter after insertion?

Securement device (Correct answer)
Tape only
Syringe
Clamp

Correct answer: Securement device

A securement device is specifically designed to hold the catheter firmly in place at the insertion site. This prevents accidental dislodgement, reduces catheter movement, and minimizes the risk of complications such as phlebitis, infection, and infiltration, thereby improving patient safety and device longevity.

Question 53: Which of the following is a contraindication to basilic vein PICC insertion?

Need for long-term antibiotics
Intact skin at the antecubital fossa
Difficult peripheral IV access
History of DVT in the ipsilateral upper extremity (Correct answer)

Correct answer: History of DVT in the ipsilateral upper extremity

Previous DVT in the ipsilateral extremity contraindicates PICC insertion in that arm due to high risk of rethrombosis and vessel compromise.

Question 54: Which patient factor MOST increases the risk of catheter-related bloodstream infection (CRBSI) and should be documented during assessment?

Hypertension
Immunocompromised status (e.g., neutropenia, HIV) (Correct answer)
Female sex
Age over 65

Correct answer: Immunocompromised status (e.g., neutropenia, HIV)

Immunocompromised patients have impaired defenses against pathogens, significantly elevating their risk for CRBSI.

Question 55: Which nerve runs in close proximity to the basilic vein in the medial upper arm, making deep basilic vein access potentially risky?

Median nerve (Correct answer)
Ulnar nerve
Musculocutaneous nerve
Radial nerve

Correct answer: Median nerve

The median nerve runs near the basilic vein in the upper arm, and inadvertent puncture or compression can cause paresthesia or nerve injury.

Question 56: A vascular access team uses peer observation during PICC insertions. This practice is BEST categorized as which type of quality activity?

Root cause analysis
Quality assurance (retrospective monitoring)
Regulatory compliance auditing
Performance improvement (prospective real-time feedback) (Correct answer)

Correct answer: Performance improvement (prospective real-time feedback)

Peer observation during procedures provides real-time, prospective feedback to improve technique and compliance with insertion bundles.

Question 57: A nurse assesses a patient's arm after peripheral IV insertion and notes the infusion is flowing by gravity but the site is cool, pale, and slightly swollen. This presentation is MOST consistent with:

Phlebitis
Infection
Infiltration (Correct answer)
Occlusion

Correct answer: Infiltration

Coolness, pallor, and swelling at the IV site indicate infiltration, where fluid is leaking into the surrounding subcutaneous tissue rather than the vein.

Question 58: In VA-BC practice, reliability in assessment refers to:

The popularity of the instrument
The speed of administration
The cost of the assessment tool
The consistency and reproducibility of results (Correct answer)

Correct answer: The consistency and reproducibility of results

Reliability refers to the consistency and reproducibility of assessment results when the test is repeated under similar conditions.

Question 59: Using differential time to positivity, which result supports catheter-related bloodstream infection?

Both cultures turn positive at the same time
Only the catheter tip culture is positive with negative blood cultures
Catheter blood culture turns positive at least 2 hours before the peripheral culture (Correct answer)
Peripheral culture turns positive 2 hours before catheter culture

Correct answer: Catheter blood culture turns positive at least 2 hours before the peripheral culture

Growth from the catheter sample at least 2 hours earlier than the peripheral sample indicates the catheter is the source.

Question 60: Which professional attribute is most valued in ethical considerations within the VA-BC field?

Working in isolation
Prioritizing personal convenience
Accountability and commitment to standards (Correct answer)
Avoiding challenging situations

Correct answer: Accountability and commitment to standards

Accountability and commitment to professional standards build trust and ensure consistent, high-quality practice.

Question 61: In Vascular Access Nurse Certification, what is the PRIMARY purpose of conducting regular safety drills and exercises?

To evaluate employee performance reviews
To ensure personnel can respond effectively in emergencies (Correct answer)
To reduce daily workload
To satisfy insurance requirements only

Correct answer: To ensure personnel can respond effectively in emergencies

Regular safety drills ensure that all personnel are prepared to respond effectively during actual emergencies. Practice builds muscle memory, identifies gaps in emergency procedures, and improves overall response times.

Question 62: When evaluating a patient for an implanted port, which physical assessment finding would be a contraindication to port placement in the chest?

History of hypertension
BMI of 28
Age over 70 years
Pacemaker or ICD leads on the ipsilateral side (Correct answer)

Correct answer: Pacemaker or ICD leads on the ipsilateral side

Pacemaker or ICD leads on the same side as the planned port create a risk of lead displacement during subclavian/cephalic vein access and complicate port placement.

Question 63: A patient with a PICC line develops erythema, warmth, and induration at the insertion site without fever. What is the MOST appropriate initial action?

Increase the frequency of dressing changes
Remove the PICC immediately
Obtain blood cultures and assess for systemic infection (Correct answer)
Apply warm compress and monitor for 24 hours

Correct answer: Obtain blood cultures and assess for systemic infection

Local site signs may indicate early CLABSI; blood cultures from the line and a peripheral site are needed to guide management before removal.

Question 64: A patient with a tunneled hemodialysis catheter is found to have CRBSI caused by S. aureus. After catheter removal, what is the MINIMUM recommended duration of systemic antibiotic therapy?

4–6 weeks (Correct answer)
10 days
14 days
7 days

Correct answer: 4–6 weeks

S. aureus CRBSIs carry a high risk of endovascular complications (endocarditis, septic emboli) requiring 4–6 weeks of systemic antibiotics after catheter removal per IDSA guidelines.

Question 65: How often should a gauze dressing on a CVC be changed if it remains clean, dry, and intact?

Every 7 days
Every 2 days (Correct answer)
Every 24 hours
Every 14 days

Correct answer: Every 2 days

Gauze dressings are changed at least every 2 days, while transparent semipermeable membrane dressings are changed at least every 7 days.

Question 66: Why is Lactated Ringer's solution contraindicated for co-administration with blood products?

It is hypertonic and causes hemolysis
Its calcium content can promote clot formation in the tubing (Correct answer)
It has an osmolarity too low for blood compatibility
It raises blood glucose and affects coagulation

Correct answer: Its calcium content can promote clot formation in the tubing

Lactated Ringer's contains 3 mEq/L of calcium, which can bind to the citrate anticoagulant in blood products and promote clot formation in the IV tubing.

Question 67: When performing a pre-insertion assessment for a central line, the nurse notes a patient's platelet count is 42,000/µL. What is the appropriate next step?

Document and notify the provider before proceeding (Correct answer)
Administer aspirin to prevent clotting complications
Cancel the central line order entirely
Proceed with insertion using extra pressure dressing

Correct answer: Document and notify the provider before proceeding

Thrombocytopenia below 50,000/µL significantly increases bleeding risk and requires provider notification for risk-benefit evaluation before insertion.

Question 68: Which statement about documenting an infiltration using a standardized scale is most accurate per INS guidance?

Photographs replace written assessment for infiltrations
Only document if the infiltrate exceeds 6 inches
Use the phlebitis scale for infiltration events
A validated, standardized scale should be used and the assessment findings, interventions, and outcome recorded (Correct answer)

Correct answer: A validated, standardized scale should be used and the assessment findings, interventions, and outcome recorded

INS recommends standardized assessment tools and documentation of findings, actions taken, and patient response for infiltration and extravasation.

Question 69: Which risk management approach is MOST effective for VA-BC professionals when evaluating potential workplace hazards?

Proactive hazard identification and assessment (Correct answer)
Reactive analysis after incidents occur
Relying solely on historical accident data
Delegating all safety decisions to management

Correct answer: Proactive hazard identification and assessment

Proactive hazard identification and assessment allows professionals to identify and mitigate risks before incidents occur, which is far more effective than reactive approaches that only address problems after they happen.

Question 70: What is the recommended dwell time for chlorhexidine gluconate (CHG) solution before accessing a needleless connector?

15 seconds (Correct answer)
5 seconds
10 seconds
30 seconds

Correct answer: 15 seconds

INS standards recommend scrubbing needleless connectors with CHG/alcohol for 5–15 seconds and allowing to dry for at least 15 seconds to ensure adequate disinfection.

Question 71: During shift assessment of a patient with a tunneled CVC, the nurse notices the external catheter length is 3 cm longer than the documented length from insertion. What does this finding suggest?

Normal variation; catheter length fluctuates with breathing
The patient has been pulling the catheter intentionally
The insertion documentation was incorrect and can be ignored
The catheter has migrated outward and tip position may have changed (Correct answer)

Correct answer: The catheter has migrated outward and tip position may have changed

A change in external catheter length indicates potential catheter migration; tip position must be verified with imaging before further use.

Question 72: A newly placed right-arm PICC has its tip in the right internal jugular vein. Which symptom might the patient report during infusion?

A gurgling or rushing sound in the ear on the same side (Correct answer)
Numbness of the fingertips
Chest pain radiating to the jaw
Pain in the left calf

Correct answer: A gurgling or rushing sound in the ear on the same side

Fluid flowing up into the internal jugular vein can cause an ear-gurgling sound or neck discomfort.

Question 73: A newly placed CVAD tip is found deep in the right atrium. Which complication is the clinician MOST concerned about?

Cardiac arrhythmias (Correct answer)
Pneumothorax

Correct answer: Soft, bouncy, and refills quickly after compression

Healthy veins feel soft and resilient and refill quickly, while cord-like veins suggest sclerosis or thrombosis.

Question 147: A patient who speaks limited English needs central line teaching. What is the most appropriate action?

Speak slowly and loudly in English
Use a family member, including a child, to interpret
Give English written instructions only
Use a qualified medical interpreter and provide materials in the patient's preferred language (Correct answer)

Correct answer: Use a qualified medical interpreter and provide materials in the patient's preferred language

Qualified interpreters and translated materials ensure accurate understanding and meet federal language access requirements.

Question 148: A disinfecting cap containing 70% isopropyl alcohol is removed from a needleless connector. What is the correct next step before accessing?

Flush with heparin before accessing
Access the connector without additional scrubbing if the cap was in place per manufacturer time (Correct answer)
Replace the needleless connector
Scrub with povidone-iodine for 2 minutes

Correct answer: Access the connector without additional scrubbing if the cap was in place per manufacturer time

Passive disinfecting caps disinfect the connector after the manufacturer's minimum dwell time, so a separate scrub is not required if used per instructions.

Question 149: A CVAD tip lying deep in the right atrium is most associated with which complication?

Brachial plexus injury
Pneumothorax
Cardiac arrhythmias and possible tamponade (Correct answer)
Phlebitis at the insertion site

Correct answer: Cardiac arrhythmias and possible tamponade

A tip in the right atrium can irritate the myocardium and, rarely, erode through it and cause tamponade.

Question 150: According to current infusion standards, what is the optimal tip location for a central vascular access device (CVAD) inserted from the upper body?

Mid-subclavian vein
Deep within the right ventricle
Brachiocephalic vein
Lower third of the superior vena cava at or near the cavoatrial junction (Correct answer)

Correct answer: Lower third of the superior vena cava at or near the cavoatrial junction

The recommended tip position for upper-body CVADs is the lower third of the SVC at or near the cavoatrial junction (CAJ). High blood flow there dilutes infusates and lowers the risk of thrombosis and vessel damage.

Question 151: When removing a catheter for suspected CRBSI and sending the tip for culture, which technique is correct?

Wipe the tip with alcohol before placing it in the container
Cleanse the skin, remove aseptically, and cut the distal 5 cm with sterile scissors into a sterile container (Correct answer)
Cut the segment closest to the hub and send it
Place the whole catheter, including hub, in a nonsterile bag

Correct answer: Cleanse the skin, remove aseptically, and cut the distal 5 cm with sterile scissors into a sterile container

The distal 5 cm segment is cut aseptically for semiquantitative culture.
