1. B
The posterior tibial artery is typically used with the dorsalis pedis artery for ABI measurement.
2. C
60 degrees is optimal for accurate Doppler velocity measurements.
3. C
Color Doppler is used to detect presence and direction of flow.
4. D
The internal carotid artery supplies the majority of blood to the brain.
5. B
Tardus-parvus waveforms suggest a proximal arterial stenosis.
6. A
Phasicity in veins reflects changes with respiration.
7. C
A normal ABI is 0.9–1.3.
8. B
Spectral broadening indicates turbulence, often from stenosis.
9. C
Posterior tibial vein is a deep vein of the leg.
10. B
Plethysmography cannot evaluate vessel patency directly.
11. A
Venous reflux results from incompetent venous valves.
12. B
Perforator veins connect superficial veins to deep veins.
13. C
High-frequency (7–10 MHz) probes are best for superficial imaging.
14. A
Linear array transducers are commonly used in vascular studies.
15. A
The popliteal artery is a continuation of the femoral artery.
16. B
Normal peripheral arteries demonstrate biphasic or triphasic waveforms.
17. C
Plaque most often forms at the carotid bulb and bifurcation.
18. C
Duplex ultrasound is the most accurate test for DVT.
19. B
A positive Doppler shift occurs when blood moves toward the transducer.
20. C
Digital subtraction angiography is the gold standard for PAD.
21. A
Subclavian steal causes reversed vertebral flow.
22. B
Vessel diameter is key for volume flow calculations.
23. A
The peroneal artery supplies the lateral leg and foot.
24. B
Pulmonary embolism is the most serious complication of DVT.
25. B
End-diastolic velocity >100 cm/s indicates >70% ICA stenosis.
26. B
The cephalic vein drains into the axillary vein.
27. B
Non-compressible veins with intraluminal echoes indicate acute DVT.
28. C
The internal jugular vein carries most venous drainage from the brain.
29. C
IVUS offers the highest spatial resolution of vessel walls.
30. D
ABI testing before and after exercise is useful for arterial insufficiency.
31. C
The dorsalis pedis artery is a continuation of the anterior tibial artery.
32. D
Increased hydration reduces, not increases, risk for DVT.
33. C
Atherosclerosis is the most common cause of renal artery stenosis.
34. C
The great saphenous vein is most often affected by varicosities.
35. B
Absence of Doppler or color flow suggests total occlusion.
36. B
The great saphenous vein is commonly harvested for CABG.
37. A
The left subclavian artery originates directly from the aortic arch.
38. C
The Doppler effect explains frequency shifts with motion.
39. A
Venous insufficiency causes swelling, pain, and skin changes.
40. B
Compression maneuvers with Doppler are a direct way to evaluate reflux.
