RVTI ARDMS EXAM QUESTIONS AND
CORRECT ANSWERS!!
___ is the most common type of arterial disease.
A. Chronic Peripheral Arterial Disease
B. varicose veins
C. abdominal aortic aneurysm
D. hardening and thickening of arterial wall, the loss of elasticity in the intimacy and media
eventually leading to formation of plaque and stenosis
E. A. and D.
A and D. Chronic Peripheral Arterial Disease, atherosclerosis or hardening and thickening of the
arterial wall, which can lead to narrowing of the arteries; stenosis
Which vessels would most likely be insinuated through the 'transtemporal window' at a
depth of 50mm with a red color signal (toward the probe)?
A. Basilar artery
B. Middle Cerebral Artery
C. Anterior Cerebral Artery
D. Posterior Cerebral Artery
B. Middle Cerebral Artery
Hemodynamically significant stenosis of the celiac axis is diagnosed with the PSV >___
,A. 180 cm/s
B. 2.0 m/s
C. 2.5 cm/s
D. 2.75 m/s
B. 2.0 m/s
A vasoconstricted vessel will have a smaller radius, a higher ___, and a higher ___?
A. pressure; velocity
B. resistance; velocity
C. pressure; resistance
D. diastolic value; resistance
B. resistance; velocity. KEY: pressure and velocity and inversely related. Pressure and radius are
directly related.
Continuous Wave Doppler requires:
A. One transmitting crystal
B. Two crystals for transmission
C. Two crystals, one transmitting, one receiving
D. One receiving crystal
C. Two crystals, one transmitting, one receiving
List the order that segmental pressures are taken.
,A. Brachial, ankle to thigh
B. Brachial, thigh to ankle
C. Ankle to thigh, brachial
D. Brachial, ankle, thigh, above knee
A. Brachial, then distal to proximal. Following brachial pressure, start with ankle (use PTA or
DPA; peroneal A. only if necessary), then calf, or BK; below knee (use PTA or DPA-that had
highest pressure), then AK; above knee (same as above-may need to use pop), then HT; high
thigh
According to the Bernoulli Principle, where will you find the lowest pressure in a vessel
with stenosis?
A. proximal to the stenosis
B. at the site of the stenosis
C. distal to the stenosis
D. in collateral vessels
B. At the site of the stenosis; the pressure being lowest at the site of the stenosis causes an
increased pressure gradient from proximal to the stenosis site. This increased gradient leads to
increased velocity of flow across the stenotic site
___ affects men <40yo that are heavy smokers, effecting the smallest, most distal vessels.
Inflammation of the vessel wall.
A. Primary Raynaud's
, B. Buerger's Disease
C. Takayasu
D. Leriche Syndrome
E. none of the above
B. Buerger's Disease
Which of the following characteristics is most suggestive of renal vein thrombosis?
A. Reduced diastolic flow in renal arteries
B. Prominent flow in the segmental and interlobar arteries
C. Turbulent flow within the kidney
D. Low resistance flow in the infrarenal arteries
A. Reduced diastolic flow in renal arteries
Turbulent flow patterns can be found ___ to stenosis.
A. proximal to stenosis
B. distal to stenosis
C. at the level of the stenosis
D. A. and C.
E. none of the above
B. distal to stenosis
ABIs are calculated by ___, with normal values ranging anywhere from ___.
