DETAILED VERIFIED ANSWERS (100% CORRECT
ANSWERS) /ALREADY GRADED A+
What is the major difference between protocols for cardiac treadmill and
claudication treadmill testing? - ANSWER: Speed 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? - ANSWER: Angina.
What is the normal diameter for the abdominal aorta? - ANSWER: 2-3 cm.
After walking 5 minutes on treadmill, patient experiences decrease in ankle pressure
of 40% on right and 15% on left. These findings suggest? - ANSWER: Claudication.
What is the correct setting for arterial volume recording? - ANSWER: AC-coupled
output.
What Doppler waveform abnormality in the lower extremity arterial circulation distal
to a hemodynamically significant stenosis show? - ANSWER: An 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?
- ANSWER: Reverse 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. - ANSWER: True.
What is the normal response of ankle pressure to exercise testing? - ANSWER: There
should be no change if normal.
With severe lower extremity arterial occlusive disease, how will distal Doppler
waveforms appear? - ANSWER: Markedly dampened, possibly making interpretation
difficult for distal segments.
What is the usual cuff pressure used in arterial volume recording? - ANSWER: 65
mmHg.
What would the CFA signal look like with aortoiliac occlusion? - ANSWER: Low
pitched and monophasic.
, T or F- Diastolic flow reversal is always present in all abnormal limbs. - ANSWER:
False. 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? - ANSWER: The 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 __________________. -
ANSWER: Relatively 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? - ANSWER: High frequency.
A normal PORH (postocclusive reactive hyperemia) response is a major velocity
increase of what percent increase in mean velocity? - ANSWER: >100%.
What are falsely elevated less frequently than tibial ankle pressures? - ANSWER: Toe
pressures.
How can a PTFE graft be identified during ultrasonographic imaging? - ANSWER: A
double line appearance of the graft walls.
Velocities measured in a reversed saphenous vein bypass graft are usually
___________ proximally and ____________ distally. - ANSWER: Higher, lower.
The volume flow rate in a reversed saphenous vein bypass graft should be? -
ANSWER: The 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? - ANSWER: Vasodilation 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? - ANSWER: Proximal to the point of
insonation.
Normal values in TcPO2 are _________. - ANSWER: 60-80 mmHg.
AAA evaluation is done pre or post prandial and why? - ANSWER: Preprandial to
minimize shadowing due to bowel gas.
What waveforms will you likely see from CFA to tibial arteries with a superficial
femoral artery occlusion? - ANSWER: Triphasic CFA and proximal SFA with
monophasic at the popliteal and tibial arteries.
