1. W1.What is the best position for the leg? Which arteries can you see with the leg in this position?
2. The scan can be started at the level of the , the CFV, and thedraining into the CFV.
3. Lumens areorin vascular imaging.
4. We remove color and use grayscale at each segment of the artery to evaluate for plaque.
Group of answer choices
True
False
5. We should place the sample gate at theof the.
6. The color is red and blue because blood flow is pulsatile.
Group of answer choices
True
False
7. The waveform is normal due to the sharp, peak, and rapid.
8. The reflected wave indicates _____ resistance.
9. The common femoral artery bifurcates into _____ and _____.
Group of answer choices
PTA & SFA
SFA & PTA
SFA & DFA
DFA & CFA
10. The velocities should be less than ___________ in lower extremities.
Group of answer choices
150 mm/sec;
150 cm/sec
100 cm/sec
100 mm/sec;
11. Why do we position the artery at 90 degrees to the sound beam in our grayscale evaluation? How do we correct if the artery is oblique?
12. If the vessel is in an oval shape on image, what position is the probe to the artery?
Group of answer choices
Sagittal
Coronal
Oblique
Transverse
13. The frame rate slows as we travel distally because the structure is superficial.
Group of answer choices
True
False
14. Why does the technician not use lots of gel?
15. The smaller branches of the SFA become largein the presence of occlusion of SFA?
True
False
16. The technician is keeping the color box straight because the vessel is at an angle.
Group of answer choices
True
False
17. What is the angle we need when performing spectral Doppler?
Group of answer choices
30 degrees
60 degrees or more
45 degrees
60 degrees or less
18. We can improve the quality of the waveform if there is lots of ‘noise’ bycolor.
19. Where is the vein in relation to the artery?
Group of answer choices
Lateral
Posterior
Anterior
Medial
20. How can you determine which is an artery and which vessel is a vein?
21. As it travels distally through the leg, the speed of the blood flowdue to gas.
22. Which two vessels can we see in the proximal medial leg? Which of those travels deeper and what happens to it distally?
23. Where is the anterior tibial artery located? How does the technician find it?
24. ordisease can contribute to the absence of the multiphasic waveform
