1. A patient requires vesicant chemotherapy infusion over 6 months. Which vascular access device is most appropriate? → Implanted port
2. When conducting a risk assessment for VA-BC operations, which factor should receive the HIGHEST priority? → Probability and severity of potential harm
3. When assessing a central venous catheter (CVC) dressing, which finding requires immediate intervention? → Visible moisture or drainage under a transparent semipermeable membrane dressing
4. Which technique is essential to prevent catheter-related infections? → Hand hygiene
5. When using the modified Seldinger technique for CVAD insertion, what is the correct sequence? → Needle → guidewire → dilator → catheter
6. When documenting assessment findings in VA-BC practice, which approach is MOST appropriate? → Record objective findings, measurements, and professional observations factually
7. What is the clinical significance of a 'reverse taper' design in PICC catheters? → The catheter narrows at the tip to reduce vessel trauma on insertion
8. What is the value of continuing education in ethical considerations for VA-BC professionals? → It keeps professionals current with evolving standards and practices
9. Which ethical principle is MOST directly applied when a vascular access nurse advocates for a patient who cannot afford a preferred device? → Justice
10. Which practice BEST supports ethically sound documentation in vascular access nursing? → Recording objective findings, patient responses, and complications accurately and promptly
11. Which personal protective equipment (PPE) principle applies to ALL VA-BC certified professionals regardless of their specific role? → PPE must be properly fitted, maintained, and replaced as needed
12. Which of the following IV solutions is classified as hypotonic? → 0.45% Normal Saline
13. According to INS standards, how frequently should administration sets used for continuous non-lipid infusions be routinely changed? → Every 96 hours or longer unless clinically indicated
14. The mean arterial pressure (MAP) is calculated using which formula? → Diastolic + 1/3 (Pulse Pressure)
15. Which factor most significantly influences the rate of IV drug distribution and therapeutic effect once a medication enters the bloodstream? → Blood flow, patient hemodynamics, and drug pharmacokinetic properties
16. What is used to secure the catheter after insertion? → Securement device
17. A hospital tracks catheter-days as a denominator in CLABSI rate calculations. Why is this metric preferred over number of patients? → It accounts for the duration of exposure and risk associated with catheter presence
18. An implanted port that is not in active use should be accessed and flushed at which interval to maintain patency? → Every 3 months
19. Which lab value should be reviewed BEFORE placing a central venous catheter to assess bleeding risk? → International Normalized Ratio (INR)
20. A unit reduces CLABSI rates and wants to sustain results. Which strategy is MOST effective for long-term sustainment? → Embedding bundle compliance into routine auditing and performance dashboards
21. Which vessel is most often used for central venous catheter insertion? → Carotid artery
22. When a central venous catheter is removed, which finding must be included in the documentation to confirm complete removal? → Catheter length intact, tip intact, and hemostasis achieved at the site
23. What is the value of continuing education in catheter types for VA-BC professionals? → It keeps professionals current with evolving standards and practices
24. 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 circular dark (anechoic) structure that compresses with pressure
25. Which sign may indicate an infection at the catheter site? → Redness and swelling
26. What is the recommended technique for flushing a peripheral IV catheter to maintain patency? → Pulsatile push-pause technique with normal saline
27. In ultrasound-guided vascular access, a vein is distinguished from an artery primarily because veins are: → Compressible with gentle probe pressure
28. Endothelial cells lining blood vessels actively prevent clot formation under normal conditions primarily by releasing: → Prostacyclin (PGI2) and nitric oxide
29. Oncotic pressure (colloid osmotic pressure) within capillaries is primarily maintained by: → Plasma albumin
30. During ultrasound-guided venipuncture, the nurse observes the needle tip pushing the anterior vessel wall inward without entering the lumen. This is called: → Tenting
