17
Q

Where are lymph nodes usually found

A

in the groin

18
Q

Fluid found infiltrating tissue is called

A

Edema

19
Q

Fluid fond at the joint thats located anterior to the bone is called

A

Joint effusion

20
Q

A cyst filled with synovial fluid found in the medial popliteal fossa is called

A

Baker cyst

21
Q

What is the normal flow of the portal vein

A

Hepatopedal (towards the liver) and minimally phasic and continuous

22
Q

Increased pressure in the portal system most likely caused by cirrhosis of the liver and other chronic liver diseases is called

A

Portal hypertension

23
Q

What is the flow direction of the ICV and hepatic veins

A

Hepatofugal and triphasic

24
Q

Occlusion of the hepatic veins and possibly ICV is called what

A

Budd-Chiari

25
Q

Enlargement of the hepatic veins and IVC is caused by what

A

Right sided heart failure

26
Q

If you find an IVC tumor what organ do you check next

A

Kidneys

27
Q

An invasion from renal cell carcinoma would cause what type of tumor

A

IVC

28
Q

What is consistent with continuous waveform in the left subclavian vein and pulsatile in the right

a) SVC syndrome
b) congestive heart failure
c) left innominate vein obstruction
d) left internal jugular vein obstruction

A

c) left innominate vein obstruction

-A continuous waveform means there is a proximal venous obstruction. Since the waveform is only on 1 side, the obstruction is isolated just proximal to that side

29
Q

Which of the following would be a normal velocity for the portal vein

a) 5 cm/sec
b) 50 cm/sec
c) 30 cm/sec
d) 15 cm/sec

A

c) 30 cm/sec

-The normal range for the portal vein is 20-40 cm/s

30
Q

What does normal coaptation indicate

a) absence of distal obstruction
b) pulsatile and spontaneous flow
c) valvular competence
d) absence of thrombus

A

d) absence of thrombus
-coaptation means the veins fully compress. There is nothing inside them

31
Q

If the portal vein is enlarged, which other vessel may show abnormality

a) hepatic artery
b) IVC
c) hepatic vein
d) coronary vein

A

d) coronary vein

32
Q

What patient position would be most useful in a patient presenting with swelling, brawny discoloration and varicose veins

a) reverse trendelenburg
b) trendelenburg
c) limb elevated
d) tip toes

A

a) reverse trendelenburg

33
Q

What is the name of the perforating veins located in the upper thigh?

a) cocketts
b) boyd’s
c) hunterian
d) dodd’s

A

d) dodd’s

34
Q

Incompetence in this valve often leads to the entire GSV being incompetent. Name this valve?

a) external iliac valve
b) terminal valve
c) mitral valve
d) sapheno-popliteal valve

A

b) terminal valve

35
Q

With the patient standing, what time value is the threshold between normal and abnormal reflux in the deep veins?

a) 0.35 seconds
b) 0.5 seconds
c) 1 second
d) 2 seconds

A

c) 1 second

36
Q

Perforating veins should be evaluated with the patient in which of the following positions?

a) supine
b) sitting, leg dependent
c) trendelenburg
d) semi-fowlers

A

b) sitting, leg dependent

37
Q

Why is doppler angle correction not necessary in venous imaging?

a) velocity is already known
b) velocity calculation is not necessary
c) doppler angle can be at 90 degrees
d) flow direction is not important

A

b) velocity calculation is not necessary
