aorta-iliac arteries.
True

without exercise induced hyperemia, is
always abnormal
To calculate the ABI, the ankle pressure should be divided by
________.
The ABI is calculated by dividing the higher of the two blood
pressure measurements in the ankles by the higher of the two
systolic blood pressure measurements at the arms.
Please calculate the left ABI for the patient who has the
following pressures:
,Right brachial: 140/90 mm/Hg Left brachial: 130/80 mm/Hg
Right ankle: 110/70 mm/Hg Left ankle: 90/45 mm/Hg
90/140

cuff should be _________ wider than the limb's diameter.
20%
Which artery can you scan at the medial malleolus?
Posterior tibial artery

failure?
Intimal hyperplasia
,All of the following patient positions could be used in duplex
scanning of the lower extremity arteries EXCEPT for
trendelenberg
What type of examination may be ordered to "unmask"
claudication symptoms in the patient who is well collateralized?
treadmill exercise testing after segmental Doppler survey

thoracic outlet syndrome is
Compression of nerves in the thoracic outlet
What type of testing is used to assure patency of the palmar arch
prior to radial artery harvest or hemodialysis access placement?
