CCI RVS PRACTICE EXAM WITH QUESTIONS
AND VERIFIED ANSWERS||LATEST 2024/2025
What is the major difference between protocols for cardiac treadmill and
claudication treadmill testinag? - CORRECT ANSWERSpeed is varied
during a cardiac treadmill test to increase heartrate to a specific target
level.
During a treadmill test, patient complains of pain in the left arm and jaw,
but denies any other pain. What is the most likely consideration? -
CORRECT ANSWERAngina.
What is the normal diameter for the abdominal aorta? - CORRECT
ANSWER2-3 cm.
After walking 5 minutes on treadmill, patient experiences decrease in
ankle pressure of 40% on right and 15% on left. These findings suggest?
- CORRECT ANSWERClaudication.
What is the correct setting for arterial volume recording? - CORRECT
ANSWERAC-coupled output.
What Doppler waveform abnormality in the lower extremity arterial
circulation distal to a hemodynamically significant stenosis show? -
CORRECT ANSWERAn absent flow recersal component, blunting of
the peak velocity and prolonged upslope and downslope.
A normal arterial volume waveform may have all EXCEPT: Swift
upstroke, sharp peak, rapid downslope bowed toward baseline, dicrotic
notch or reverse flow component? - CORRECT ANSWERReverse
flow component because it is part of a Doppler waveform not volume
waveform.
,T or F- Most analog Doppler analysis is qualitative, assessing for
presence or absence of characteristics. - CORRECT ANSWERTrue.
What is the normal response of ankle pressure to exercise testing? -
CORRECT ANSWERThere should be no change if normal.
With severe lower extremity arterial occlusive disease, how will distal
Doppler waveforms appear? - CORRECT ANSWERMarkedly
dampened, possibly making interpretation difficult for distal segments.
What is the usual cuff pressure used in arterial volume recording? -
CORRECT ANSWER65 mmHg.
What would the CFA signal look like with aortoiliac occlusion? -
CORRECT ANSWERLow pitched and monophasic.
T or F- Diastolic flow reversal is always present in all abnormal limbs. -
CORRECT ANSWERFalse. It may be absent in vasodialted limbs.
What is the most important reason Doppler evaluations should be
performed with patient in a basal state and warm temperature? -
CORRECT ANSWERThe results are influenced by the patient's
peripheral resistence.
Audible Doppler venous signals are usually low frequency and vary with
respiration, where as normal arterial signals in the arms and legs are
__________________. - CORRECT ANSWERRelatively high
frequency with pulsatile components and dont change with respiration.
When listening with CW Doppler over a stenotic lesion you will hear
high frequency or low frequency sound? - CORRECT ANSWERHigh
frequency.
,A normal PORH (postocclusive reactive hyperemia) response is a major
velocity increase of what percent increase in mean velocity? -
CORRECT ANSWER>100%.
What are falsely elevated less frequently than tibial ankle pressures? -
CORRECT ANSWERToe pressures.
How can a PTFE graft be identified during ultrasonographic imaging? -
CORRECT ANSWERA double line appearance of the graft walls.
Velocities measured in a reversed saphenous vein bypass graft are
usually ___________ proximally and ____________ distally. -
CORRECT ANSWERHigher, lower.
The volume flow rate in a reversed saphenous vein bypass graft should
be? - CORRECT ANSWERThe same throughout the graft even though
the velocities may differ.
With both arterial obstructive disease and distal ischemia, what happens
to vessel size and distal resistance? - CORRECT
ANSWERVasodilation opens to attempt to increase nutrive blood flow
to the extremity and distal resistance decreases.
When you have a damped Doppler velocity waveform of the subclavian
artery, where would the significant lesion be located? - CORRECT
ANSWERProximal to the point of insonation.
Normal values in TcPO2 are _________. - CORRECT ANSWER60-80
mmHg.
AAA evaluation is done pre or post prandial and why? - CORRECT
ANSWERPreprandial to minimize shadowing due to bowel gas.
What waveforms will you likely see from CFA to tibial arteries with a
superficial femoral artery occlusion? - CORRECT ANSWERTriphasic
, CFA and proximal SFA with monophasic at the popliteal and tibial
arteries.
When calculating the ABI pressure ratio, what pressures are used? -
CORRECT ANSWERAnkle pressure/The higher arm pressure.
Which ABI would be higher between Claudication and rest pain? -
CORRECT ANSWERClaudication is higher (0.5-0.9)
Rest pain is lower (< 0.5)
What happens to a patients digital pressures when the hand is immersed
in cold water if they have Raynaud's disease? - CORRECT
ANSWERThey decrease or disappear all together.
Define coarctation of the aorta. - CORRECT ANSWERCoarctation of
the aorta is a narrowing of the aorta most commonly found just distal to
the origin of the left subclavian artery.
Define compartment syndrome. - CORRECT ANSWERA serious
condition that involves increased pressure in a muscle compartment. It
can lead to muscle and nerve damage and problems with blood flow.
What is digital subtraction arteriography? - CORRECT ANSWERa
method in which radiographic images of blood vessels filled with
contrast material are digitized and then subtracted from images obtained
before administration of the material. The method increases the contrast
between the vessels and the background.
Where is the usual site for percutaneous lower extremity (or any)
angiography? - CORRECT ANSWERCommon femoral artery.
The common radiologic terms "inflow", "outflow" and "runoff" refer
respectively to what? - CORRECT ANSWERAortoiliac,
femoropopliteal and trifurcation arteries.
