ARDMS RVT Practice Exam — FULL SET (1–50 with Answers & Rationales)
1.
Which Doppler finding is most consistent with a hemodynamically significant arterial stenosis
greater than 50% diameter reduction?
A. Decreased peak systolic velocity with monophasic waveform
B. Increased peak systolic velocity with post-stenotic turbulence
C. Absent flow signal
D. Continuous venous waveform
Answer: B
Rationale: Significant stenosis produces velocity acceleration and turbulence distal to
narrowing.
