3. What is the primary ethical obligation of a VT professional when a conflict of interest arises during transcranial doppler imaging activities? → Disclose the conflict to all relevant parties and recuse from the decision if necessary
4. Which quality assurance method is most commonly applied in lower & upper extremity arterial to verify that VT professional standards are being met? → Structured audits, peer reviews, and performance metrics aligned with industry benchmarks
5. Which practice supports patient dignity during vascular imaging? → Offering proper draping
6. How should a vascular technician respond if a patient feels faint during a procedure? → Lay the patient flat and monitor

8. What is the purpose of a pulse volume recording (PVR)? → Assess blood volume changes
9. At which anatomical junction does the small saphenous vein (SSV) typically terminate? → Saphenopopliteal junction in the popliteal fossa
10. At the saphenofemoral junction (SFJ), the GSV drains into which vessel? → Common femoral vein
