Vascular Final Study Guide Part 4
1.
Normal flow in the renal arteries and arteries of the kidney is
A.
Low resistance
B.
High resistance
C.
May show evidence of both high and low resistance
D.
Monophasic
Correct Answer
,A. Low resistance
Explanation
The normal flow in the renal arteries and arteries of the kidney is characterized by low
resistance. This means that there is minimal impedance to the blood flow, allowing it to flow
easily through the arteries. This is important for the kidneys as they require a steady and
efficient blood supply to perform their filtration and waste removal functions effectively. Low
resistance in these arteries ensures that an adequate amount of blood reaches the kidneys,
maintaining their proper function.

Significant stenosis in relation in the renal arteries is considered to be
A.
40% or greater
B.
50% or greater
C.
60% or greater
D.
80% or greater
,Correct Answer
B. 50% or greater
Explanation
A significant stenosis in relation to the renal arteries is considered to be 50% or greater. This
means that if there is a blockage or narrowing in the renal arteries that reduces the blood flow
by 50% or more, it is considered to be significant. This level of stenosis can lead to decreased
kidney function and potentially result in conditions such as renal artery stenosis or
hypertension.

In venous duplex Doppler scanning, Acute DVT may exhibit all of the followng characteristics,
EXCEPT
A.
Spongy texture
B.
Poor attachment to wall
C.
Highly echogenic
, D.
Dilated vessel
Correct Answer
C. Highly echogenic
Explanation
Acute DVT may exhibit spongy texture, poor attachment to the wall, and dilated vessel
characteristics. However, it is not expected to be highly echogenic. The term "echogenic" refers
to the ability of a structure to produce echoes in an ultrasound scan. In the context of venous
duplex Doppler scanning, highly echogenic would mean that the DVT appears bright and
reflective on the ultrasound image, which is not typical for an acute DVT.

In TRV, the popliteal vein does not fill with color at all. One must consider all of the following
possibilities EXCEPT
A.
DVT
B.
Poor angle of insonation
C.
The filter is set too high
