- Q1
What do perforating veins do?
help gather blood from the calf muscles�
provide for connections between the various superficial veins of the lower extremity�
regulate body temperature
Connect the deep veins with the superficial veins moving blood from the superficial to the deep system
30s - Q2
The most accurate method to determine that a vein at any given point is thrombus free is to:
Obtain phasic and augmentable venous Doppler signals from the vein�
Directly visualize an anechoic venous lumen�
Completely compress the vein walls together�
Display color completely filling a vein�
30s - Q3
Normal lower extremity venous Doppler signals respond to normal breathing patterns by:
Increasing during inspiration�
Becoming continuous, monophasic signals during expiration�
Ceasing during inspiration�
Ceasing during expiration�
30s - Q4
A pulsatile lower extremity venous Doppler signal can be expected with all of the following conditions except:�
congestive heart failure�
an iliac vein thrombosis
a traumatic arteriovenous fistula��
pulmonary hypertension�
30s - Q5
The three components of Virchow's triad are:
lack of competent valves, venous stasis, inefficient calf muscle pump
lack of competent valves, prolonged standing, family history�
Venous stasis, vessel wall injury, and hypercoagulability�
venous stasis, prior thrombus, hypercoagulability�
30s - Q6
All of the following are common symptoms associated with deep venous thrombosis except:�
lower extremity swelling
Calf tenderness and pain
lower extremity discoloration�
Chest pain�
30s - Q7
While examining a patient supine on an examination table with a slight tilt, you find it difficult to visualize the calf veins. What step can be done to visualize the vein?�
turn up the air conditioning in the room�
have the patient drink 16� ounces of water�
Have the patient sit at the side of the bed and dangle their legs
put the patient into a Trendelenburg position�
30s - Q8
A major storage area for blood in the lower extremity is:
soleal sinus veins�
perforating veins�
gsv�
gastrocnemius veins�
30s - Q9
What technique can be employed to improve adequate compression of the superficial femoral vein as it passes through the adductor canal?�
patient should be asked to Valsalva
Pressure should be applied along the posterior aspect of the leg�
patient should be placed in reverse Trendelenburg position�
compressions should be performed with a curved linear array transducer
30s - Q10
All of the following are associated with phlegmasia cerulea dolens except:�
Blanching
Arterial ischemia�
Massive swelling�
Cyanosis
30s - Q11
Two drugs commonly used to treat patients with deep venous thrombosis include:�
warfarin and heparin�
aspirin and warfarin�
aspirin and clopidogrel�
aspirin and heparin�
30s - Q12
Thrombi in the upper extremity are rarely caused by stasis because:�
the changes in intrathoracic pressure limits stasis in the upper extremities
the veins of the arm do not have a counterpart to soleal sinuses�
the arms are more mobile so there is less chance for stagnation occurs
the effects of hydrostatic pressure help counteract the tendency toward stasis
30s - Q13
The median cubital veins connect the:
basilic and brachial veins
cephalic and brachial veins�
cephalic and basilic veins�
basilic and deep brachial veins�
30s - Q14
Which vessel is most likely the site of thrombus with a PICC line insertion?
internal jugular vein�
brachial vein�
basilic vein�
median cubital vein
30s - Q15
If a patient takes a breath through pursed lips, what result will be evident in the subclavian vein?�
the vein walls will collapse, confirming the lack of thrombus
the impact of hydrostatic pressure on the vein will be alleviated�
the venous Doppler signals will become more pulsatile�
the vein will dilate making it easier to obtain a Doppler signal�
