Terms in this set (36)
T/F: The superficial veins have an accompanying artery and the deep veins do not.
T/F: Persistent retrograde flow in the internal or external jugular veins suggests obstruction in the innominate vein.
T/F: The axillary artery extends from the first rib to the axilla.
T/F: Arm pressure measurements should not be obtained on an arm with a hemodialysis access.
T/F: Normal subclavian spectral waveforms should demonstrate a high resistance flow pattern.
T/F: Waveforms obtained from within a stenosis will display low velocities and more distally, spectral broadening indicative of post-stenotic turbulence.
T/F: The Right CCA arises from the innominate artery.
