Module 4 Review Questions

Question 1

What is the most appropriate transducer for mapping of the upper extremity superficial venous system?

Answer 1

10-18 MHz straight linear array

Question 2

During an upper extremity venous examination, the technologist has made the patient take in a quick deep breath through pursed lips while viewing the subclavian vein. What is the purpose of this action?

Answer 2

collapse/coapt the subclavian vein

Question 3

What is the primary method used to determine the presence of thrombus in the extremity veins?

Answer 3

transducer compression of the veins

Question 4

At the confluence with which vein does the brachian vein become the axillary vein?

Answer 4

basilic vein

Question 5

Which vessel connects the basilic and cephalic veins?

Answer 5

median cubital vein

Question 6

To maximize venous pressure and distension in what position should the patients limb be placed when mapping the superficial venous system?

Answer 6

dependent

Question 7

Which forearm vessels are NOT routinely evaluated during upper extremity venous duplex testing?
a. basilic and cephalic veins
b. basilic and ulnar veins
c. cephalic and radial veins
d. radial and ulnar veins

Answer 7

d

Question 8

A patient presents to the vascular lab for upper extremity venous evaluation with face swelling and prominent veins on the chest and neck. What do these findings suggest?

Answer 8

superior vena cava thrombosis

Question 9

Why will using a reverse Trendelenburg position to examine the lower extremity venous system make the exam more difficult?

Answer 9

veins without thrombus will be harder to compress

Question 10

For routine operation of a vascular lab the use of a high frequency linear transducer (10 to 18 MHz) is recommended for the evaluation of which of the following?
a. superficial vein reflux
b. perforators
c. distal femoral vein
d. iliac veins

Answer 10

a

Question 11

In what case will indirect assessment of the iliac veins and IVC using Doppler at the common femoral veins suggest evidence of obstruction?

Answer 11

The Doppler spectrum exhibits continuity

Question 12

When can a false-negative D dimer be seen in the presence of DVT?

Answer 12

Assay cannot detect low levels of fibrin

Question 13

During a lower extremity venous duplex examination, a thin, white structure is noticed moving freely in the lumen of the vein. What does this most likely represent?

Answer 13

valve leaflet

Question 14

Which veins are one of the major blood reservoirs located in the calf?
a. the tibial veins
b. the small saphenous vein
c. soleal sinus vein
d. popliteal vein

Answer 14

c

Question 15

How many common configurations does the thigh portion of the great saphenous vein have?

Answer 15

5

Question 16

Which of the following is a kidney-shaped structure sometimes imaged in the groin region?
a. abscess
b. synovial cyst
c. hernia
d. lymph node

Answer 16

d

Question 17

Into which of the following vessels does the small saphenous vein terminate?
a. popliteal vein
b. gastrocnemius vein
c. distal femoral vein
d. any of the above

Answer 17

d

Question 18

Within which of the following positions can a true saphenous vein be determined?
a. deep muscular fascia
b. subdural lipid layer
c. saphenous fascia
d. anterior vascular compartment

Answer 18

c

Question 19

Why is Doppler angle correction not necessary in venous imaging?

Answer 19

velocity calculation is not necessary

Question 20

Compression of the subclavian veins that results in thrombosis is called:

Answer 20

Paget-Schroetter Syndrome
