1. Which of the following will NOT result in bilateral changes in
the Doppler spectra of the carotid arteries?
1. Intra-aortic balloon pump
2. Brain death
3. Subclavian steal
4. Aortic root or valve stenosis
2. What is the provocative maneuver of reactive hyperemia used
to demonstrate during the duplex evaluation of the
extracranial cerebrovascular system?
1. The presence of congenitally small vertebral arteries

severe stenosis or an occlusion
need to be present?/
1. The bilateral common carotid arteries
2. The subclavian artery distal to the vertebral artery
3. The brachiocephalic or subclavian artery proximal to the
vertebral artery origin
4. The vertebral arteries
4. A patient presents for extracranial carotid duplex
examination with symptoms of right-sided facial droop. Where
