✍️ Sample RVT Questions & Answers
1. On a PVR tracing, which feature represents the dicrotic notch, and what does its absence indicate?
The dicrotic notch on the descending limb of the PVR waveform represents aortic valve closure; its absence distal to a stenosis reflects dampening of pulsatility.
2. Which statement correctly describes the relationship between vessel radius and flow resistance according to Poiseuille's law?
Poiseuille's law states R = 8ηL / πr⁴, meaning a 50% reduction in radius increases resistance 16-fold.
3. A vein graft exhibiting low-velocity, monophasic waveforms throughout its length without a focal stenosis most likely represents which condition?
Uniformly low velocities with monophasic waveforms throughout a graft suggest poor inflow or high outflow resistance, placing the graft at risk for thrombosis.
4. The time-gain compensation (TGC) control is used primarily to:
TGC amplifies returning echoes from deeper structures to compensate for the progressive attenuation of ultrasound as it travels through tissue.
5. Which scenario represents an improper use of CME credits for RVT renewal?
Non-accredited in-service training sessions do not qualify as CME, even if they involve medical equipment.
6. During a venous reflux study, what duration of retrograde flow in the great saphenous vein is considered pathological?
Reflux duration exceeding 0.5 seconds in superficial veins (and 1.0 second in deep veins) is considered pathological by most accepted criteria.
