Final Flashcards
Veins can most accurately be defined as what type of vessel?
A.) Capacitance
B.) Resistance
A.) Capacitance
Hydrostatic pressure is best defined as the pressure within a vessel related to the weight of a column of blood in relation to a reference point.
A.) True
B.) False
A.) True
When discussing hydrostatic pressure or anything else in the vascular system, what is our reference point?
A.) Right ventricle
B.) Right atrium
C.) Whatever portion is most distal of proximal
D.) Left atrium

A Thrombus within which of the following carries the greatest risk of a major pulmonary embolism? A.) Popliteal artery B.) Lesser saphenous vein C.) Posterior tibial vein D.) Popliteal vein
D.) Popliteal vein
The Doppler Spectral waveform obtained in the common femoral vein is noted to be phasic. Color doppler fills the lumen of the femoral vein completely and the popliteal and greater saphenous vein’s are compressible. Is this phasicity a normal finding?
A.) Yes
B.) No
A.) Yes
What is the name of the superficial vein that is found on the medial aspect of the lake? A.) Soleal Vein B.) Common femoral vein C.) Greater saphenous vein D.) Popliteal vein
C.) Greater saphenous vein
The characteristics of a normal venous Doppler signal from the lower extremity include all of the following except: A.) Competent valves B.) Augmentation C.) Spontaneity D.) Pulsatility
The most important diagnostic criteria during a lower extremity venous exam is which one of the following?
A.) Anechoic vessel
B.) Complete compression of vein from transducer pressure
C.) Color filling vessel
D.) Augmentation
B.) Complete compression of vein from transducer pressure
Starling forces are described as the forces that move fluid in and out of vessels.
True - or- False
True
When starling forces become unbalanced, what is the result? A.) Venous reflux  B.) Collapsed vein C.) Edema D.) Decreased venous pressure
C.) Edema
Normal Venus flow should have all of the following: Physicity, pulsatility, Spontaneous flow, Augmentation, & competent Valves
A.) True
B.) False
B.) False
Why are veins so easily collapsible? A.) Valves assist in the collapse. B.) Thin walled. C.) Lowe venous pressure. D.) Respiration assist in collapse.
B.) Thin walled
Return of Venus flow from the legs to the heart happens by all except: A.) Venous valves. B.) Calf muscle pumps. C.) Peristalsis. D.) Inspiration.
C.) Peristalsis.
You are examining extra doppler in the femoral vein at mid thigh. You compress the calf firmly, what should occur in a normal patient?
A.) Venus flow becomes pulsatile.
B.) Venus flow is halted.
C.) Venus flow is increased distal to compression.
D.) Venus flow changes direction.
When laying flat, Hydrostatic pressure is highest where?
A.) Ankle.
B.) Arm.
C.) Equal.
C.) Equal
The vessels responsible for helping to regulate body temperature are:
A.) Perforators.
B.) Deep vein’s.
C.) Superficial veins.
C.) Superficial veins.
The principal mechanism of resistance in a vein is the shape of the vessel.

B.) CFV, FV, PTV’s, Peroneal’s, ATV’s
C.) CFV, Profunda, FV, PTV’s ATV’s
D.) CFV, FV, Popliteal, PTV’s, Peroneal’s, ATV’s
D.) CFV, FV, Popliteal, PTV’s, Peroneal’s, ATV’s

C.) Perform entire exam as normal without augmentation of the popliteal area only.
D.) Perform entire exam as normal without any augmentation.
D.) Perform entire exam as normal without any augmentation.
