VA-BC™ Vascular Access Board Certified Examination — Questions and Answers

Question 1: When teaching a patient to perform a saline flush at home, which technique should be emphasized?

Use a pulsatile (push-pause) technique to create turbulence that clears the lumen (Correct answer)
Use the smallest syringe available to minimize pressure
Flush with tap water if saline is unavailable
Flush rapidly in a single push to ensure patency

Correct answer: Use a pulsatile (push-pause) technique to create turbulence that clears the lumen

The pulsatile push-pause flushing technique creates turbulent flow that is more effective at clearing fibrin and debris from the lumen.

Question 2: A patient's PICC was placed 5 days ago and the nurse observes 2 cm of external catheter that was not present on the previous shift's documentation. This most likely indicates:

Fluid overload
Catheter fracture
Catheter migration outward (tip retraction) (Correct answer)
Normal catheter settling

Correct answer: Catheter migration outward (tip retraction)

An increase in external catheter length means the tip has retracted proximally, potentially out of the SVC, and requires radiographic confirmation before use.

Question 3: Which assessment finding is MOST concerning during a routine PICC flush and requires immediate provider notification?

Slight discomfort at insertion site during flushing
No blood return, severe resistance, and patient reports arm pain (Correct answer)
Mild resistance relieved by arm repositioning
Blood return is slow but present

Correct answer: No blood return, severe resistance, and patient reports arm pain

Absent blood return with severe resistance and arm pain suggests catheter thrombosis or fracture, which is a medical emergency requiring immediate provider notification.

Question 4: What role does calibration play in maintaining technical accuracy for Peripherally Inserted Central Catheter Certified Nurse professionals?

It ensures instruments produce accurate, consistent results over time (Correct answer)
It is only necessary for new equipment
It only matters during inspections
It is optional for advanced professionals

Correct answer: It ensures instruments produce accurate, consistent results over time

Regular calibration ensures instruments continue producing accurate results over time.

Question 5: A nurse notes resistance when flushing a PICC line. The FIRST action should be:

Apply forceful pressure to clear the obstruction
Instill 2 mg tPA without further assessment
Remove the catheter immediately
Assess for kinking, clamp position, or patient arm position (Correct answer)

Correct answer: Assess for kinking, clamp position, or patient arm position

Mechanical causes such as kinking, a closed clamp, or a kinked extension set must be ruled out before assuming a clot occlusion.

Question 6: What differential time to positivity (DTP) threshold, when the PICC culture turns positive earlier than the peripheral culture, is diagnostic for catheter-related bloodstream infection (CRBSI)?

≥6 hours
≥1 hour
≥4 hours
≥2 hours (Correct answer)

Correct answer: ≥2 hours

A DTP of ≥2 hours — the central line culture turning positive at least 2 hours before the peripheral culture — is the accepted diagnostic threshold for CRBSI.

Question 7: Where should PICC tip terminate?

Right atrium
Lower third of superior vena cava (Correct answer)
Subclavian vein
Right internal jugular

Correct answer: Lower third of superior vena cava

The ideal tip termination for a PICC is in the lower third of the superior vena cava (SVC), just above the cavoatrial junction. This placement ensures that infused medications are rapidly diluted by the high blood flow in the SVC, minimizing irritation to the vessel wall and reducing the risk of complications like cardiac arrhythmias or vessel erosion. Correct tip placement is critical for safe and effective therapy.

Question 8: A nurse attempts to flush a PICC line and encounters resistance. What is the FIRST action the nurse should take?

Assess for catheter kinking or positional changes (Correct answer)
Instill a thrombolytic agent
Immediately remove the PICC line
Forcefully flush with a 10 mL syringe

Correct answer: Assess for catheter kinking or positional changes

Before any intervention, the nurse should assess for mechanical causes such as catheter kinking, patient position, or external clamping that may be causing the resistance.

Question 9: What solution is used to flush PICC lines?

Chlorhexidine
Ethanol
Normal saline or heparin (Correct answer)
Distilled water

Correct answer: Normal saline or heparin

To maintain patency and prevent occlusion of PICC lines, they are routinely flushed with either normal saline or a dilute heparin solution. Normal saline is used to clear medication residue and prevent intraluminal clotting, while heparin, an anticoagulant, is often used for catheters that are not in continuous use to prevent thrombus formation within the lumen. The specific solution depends on facility policy and catheter type.

Question 10: Which filter size is required when administering lipid emulsions through a PICC to prevent particulate matter from reaching the patient?

5-micron filter
0.22-micron filter
1.2-micron filter (Correct answer)
0.45-micron filter

Correct answer: 1.2-micron filter

A 1.2-micron filter is required for lipid-containing solutions because the smaller 0.22-micron filter would remove the lipid particles from the emulsion.

Question 11: In Peripherally Inserted Central Catheter Certified Nurse, 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 satisfy insurance requirements only
To reduce daily workload

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.

Question 12: Which documentation practice BEST demonstrates regulatory compliance for PICC certified professionals?

Filing documents only when audited
Keeping informal handwritten notes
Relying on memory for routine procedures
Maintaining organized, dated, and signed records of all activities (Correct answer)

Correct answer: Maintaining organized, dated, and signed records of all activities

Organized, dated, and signed records demonstrate systematic regulatory compliance.

Question 13: A nurse receives a new order to administer diazepam (Valium) IV via PICC. What should the nurse assess before infusing this medication?

Whether the patient is NPO status
Compatibility, as diazepam can adsorb to PVC tubing and precipitate in many IV solutions (Correct answer)
Whether the PICC has been flushed with heparin in the last 8 hours
The patient's most recent CBC result

Correct answer: Compatibility, as diazepam can adsorb to PVC tubing and precipitate in many IV solutions

Diazepam adsorbs to PVC tubing and precipitates in most aqueous IV solutions, requiring non-PVC tubing and direct injection or a short non-PVC infusion line.

Question 14: A PICC placed in the right arm has migrated into the right internal jugular vein as confirmed on X-ray. The most appropriate next action is:

Have the patient turn their head toward the insertion side and reposition under fluoroscopy (Correct answer)
Withdraw the catheter 2 cm and re-X-ray
Continue use since the IJ is an acceptable central vein
Remove the catheter and place a new one

Correct answer: Have the patient turn their head toward the insertion side and reposition under fluoroscopy

Repositioning maneuvers (head turn, arm repositioning, fluoroscopic guidance) can redirect a malpositioned PICC from the IJ back into the SVC.

Question 15: What is the function of valves in veins?

Prevent backflow of blood (Correct answer)
Deliver nutrients
Regulate temperature
Detect infection

Correct answer: Prevent backflow of blood

Veins contain one-way valves that play a crucial role in venous circulation. These valves open to allow blood to flow towards the heart and then close to prevent the backflow of blood, especially against gravity. This mechanism ensures efficient venous return and prevents pooling of blood in the extremities, contributing to overall circulatory health.

Question 16: What is used to clean the site before access?

Alcohol
Chlorhexidine (Correct answer)
Soap and water
Hydrogen peroxide

Correct answer: Chlorhexidine

Chlorhexidine gluconate (CHG) is the recommended antiseptic for skin preparation before accessing a central line, including a PICC. Its broad-spectrum antimicrobial activity and persistent effect on the skin significantly reduce the bacterial load at the insertion site. This helps to minimize the risk of introducing pathogens into the bloodstream during catheter access.

Question 17: Which landmark is used to estimate PICC insertion length before catheter placement?

Insertion site to the sternal notch to the third intercostal space (Correct answer)
Mid-arm to the clavicle
Antecubital fossa to the right ear lobe
Nipple line to the insertion site

Correct answer: Insertion site to the sternal notch to the third intercostal space

Measuring from the insertion site to the sternal notch and then down to the third intercostal space approximates the distance to the cavoatrial junction.

Question 18: How to identify bloodstream infection?

Low blood pressure
Cough and sore throat
Nausea and vomiting
Fever and positive blood culture (Correct answer)

Correct answer: Fever and positive blood culture

A bloodstream infection, particularly a Central Line-Associated Bloodstream Infection (CLABSI), is typically identified by the presence of systemic signs of infection, such as fever, chills, and malaise. The definitive diagnosis requires a positive blood culture, where bacteria or fungi are isolated from the patient's blood, confirming the presence of pathogens in the bloodstream. This combination of clinical symptoms and laboratory confirmation is essential for accurate diagnosis and treatment.

Question 19: What is the maximum hang time for lipid-containing parenteral nutrition (3-in-1 admixture) administered via a PICC per INS guidelines?

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

Correct answer: 24 hours

Per INS guidelines, 3-in-1 TPN admixtures containing lipids should be infused within 24 hours of compounding to prevent lipid destabilization and microbial growth.

Question 20: In PICC practice, what happens when regulations are updated?

Professionals must update knowledge and practices to meet new requirements (Correct answer)
Changes apply only to new professionals
Previous certifications are revoked
Existing professionals are grandfathered in

Correct answer: Professionals must update knowledge and practices to meet new requirements

All professionals must update their knowledge and practices when regulations change.

Question 21: Which antiseptic agent is the PREFERRED skin preparation for PICC insertion in patients over 2 months of age?

70% isopropyl alcohol alone
>0.5% chlorhexidine gluconate in 70% isopropyl alcohol (Correct answer)
Benzalkonium chloride
Povidone-iodine 10%

Correct answer: >0.5% chlorhexidine gluconate in 70% isopropyl alcohol

Chlorhexidine-alcohol solution provides superior residual antimicrobial activity compared to povidone-iodine and alcohol alone, per CDC and INS guidelines.

Question 22: The purpose of using a vein finder or near-infrared device prior to PICC insertion is to:

Identify superficial vein anatomy before ultrasound assessment (Correct answer)
Measure central venous pressure
Confirm catheter tip placement
Replace ultrasound guidance

Correct answer: Identify superficial vein anatomy before ultrasound assessment

Near-infrared devices visualize superficial veins for preliminary assessment but do not replace ultrasound for real-time needle guidance during insertion.

Question 23: Which concentration of heparin is recommended by ISMP for PICC flush solutions in adult patients to reduce the risk of medication errors?

10 units/mL (Correct answer)
500 units/mL
100 units/mL
1,000 units/mL

Correct answer: 10 units/mL

ISMP recommends 10 units/mL heparin flush for adult PICCs to reduce the risk of heparin-induced complications while maintaining catheter patency.

Question 24: When a PICC professional encounters an unexpected result during a procedure, the FIRST action should be to:

Repeat the procedure immediately
Continue and address it later
Report without preliminary assessment
Stop, assess the situation, and determine whether to proceed or seek guidance (Correct answer)

Correct answer: Stop, assess the situation, and determine whether to proceed or seek guidance

Stopping to assess unexpected results is critical for safety and quality.

Question 25: A patient asks if they can use their PICC arm for moderate weightlifting. What should the nurse document as the education provided?

Resistance bands are an acceptable alternative
Weightlifting is safe after the first week
No arm restrictions apply once the dressing is secured
Heavy lifting and strenuous arm activity should be avoided to prevent tip malposition or thrombosis (Correct answer)

Correct answer: Heavy lifting and strenuous arm activity should be avoided to prevent tip malposition or thrombosis

Heavy or repetitive arm exercise can cause PICC tip migration and increases thrombosis risk.

Question 26: When a PICC professional identifies a potential regulatory violation, the CORRECT first step is to:

Document the violation and report through proper channels (Correct answer)
Discuss it casually with coworkers
Address it only if directly affected
Wait to see if it resolves on its own

Correct answer: Document the violation and report through proper channels

Proper documentation and reporting through established channels ensures accountability.

Question 27: Ethanol lock therapy is used in PICC management primarily to address which complication?

Mechanical phlebitis
Air embolism prevention
Recurrent catheter-associated bloodstream infections in high-risk patients (Correct answer)
Post-insertion hematoma

Correct answer: Recurrent catheter-associated bloodstream infections in high-risk patients

Ethanol lock therapy is an antimicrobial strategy used to prevent recurrent CRBSIs in high-risk patients, particularly those requiring long-term PICC access.

Question 28: What is the BEST way for a Peripherally Inserted Central Catheter Certified Nurse professional to stay current with regulatory changes?

Monitor regulatory bodies, attend CE, and participate in professional associations (Correct answer)
Depend on colleagues to share updates
Check regulations only during renewal
Rely solely on employer notifications

Correct answer: Monitor regulatory bodies, attend CE, and participate in professional associations

Staying current requires monitoring agencies, attending CE, and participating in professional associations.

Question 29: A patient is being discharged with a PICC for home IV antibiotics. Which topic is least relevant to their discharge education?

How to report a wet or loose dressing
Signs and symptoms of PICC complications
How to flush the PICC before and after medication administration
The nurse's home address for emergency contact (Correct answer)

Correct answer: The nurse's home address for emergency contact

Personal contact information for the nurse is not appropriate; patients should be directed to the home health agency or on-call line.
