Final Mock Exam Flashcards
T/F The purpose of the Valsalva’s maneuver is to test the efficiency of the valves
true
T/F This can lead to varicose veins due to the increased pressure in the superficial system
true
T/F Augmentation is used to force a bolus of blood quickly up the venous tree
true
T/F If augmentation response is good, this proves the lack of occlusive obstruction between the probe and the area of squeeze(calf)
true
If the augmentation response is not adequate such as a wrap around flow pattern, which of the following statements is/are true:
A-stop the test
B-try again, you may not have squeezed with enough force
C-ask a coworker to augment with both hands-the leg may be swollen or large
D-if the compressions were not adequate due to swelling, size etc and augmentation is poor, there may be a missed DVT
Choose from:
A &D
B&C&D
B
C
D
Continuous, non-phasic flow in the CFV when the compressions did not reveal a DVT, points to what diagnosis-
A-patient is not holding their breath
B-there is a missed DVT in the femoral vein
C-there is poor augmentation
D-there is likely a DVT in the ipsilateral iliac vein
there is likely a DVT in the ipsilateral iliac vein
If the Iliacs are not seen due to pt body habitus, gas etc, how would you expand the test?
describe
Examine the IVC below the liver for phasicity
Above the renal arteries

Infrarenal portion and iliacs
High resistant,higher pulsatility
T/F The distal aorta and iliacs may assume a low resistant flow pattern while exercising

T/F Intrarenal tardus parvus waveform indicates a hemodynamically significant MRA stenosis
true
what is the most common cause of renal artery stenosis?
- Fibromuscular dysplasia
- Renal failure
- Smoking
- Atherosclerosis
- Hyperlipidemia
atherosclerosis
Emboli or insitu thrombus causes what condition in the kidney? A-cyst B-tardus parvus waveform C-RA aneurysm D-infarct
infarct
A malformation that causes arterial pulsations within the renal venous tree is- A-arterial venous fistula B-tardus parvus waveform C-duplicated renal artery D-pseudoaneurysm
A-arterial venous fistula
how may arterial venous fistulas occur?
congenital or aquired
- tumour
- trauma
- iatrogenic
How much flow does the portal vein supply to the liver?
70%
Normal blood flow velocity of the \_\_\_\_\_ \_\_\_\_\_ is 13-23 cm/sec with an average of 18 cm/sec A-hepatic artery B-portal vein C-splenic vein D-mesenteric artery
potal vein
T/F Normal hepatic arterial PSV in a fasting adult patient is approximately 30–40 cm/sec, and EDV is 10–15 cm/sec .
true
pictures on the mock exam
look at
When the intimal wall pulls away from the muscular wall in an artery, this indicates which condition-
dissection
Which statement regarding Paget-Schroetter syndrome is true-
A-Most common cause of upper extremity DVT
B-Seen in older adults
C-Due to effort-induced thrombosis of the Jugular vein
D-Associated with strenuous upper body exercise or repetitive movements
D-Associated with strenuous upper body exercise or repetitive movements
T/F VAD’s can be a cause of upper extremity DVT-
true
list 3 uses for VAD’s
- chemotherapy
- nutrition
- other meds
T/F Lymphedema in the arm is most commonly seen following mastectomy with removal of lymph nodes in the axilla
true
T/F Right replaced hepatic artery occurs more commonly than left replaced hepatic artery-
true
It arises from which artery?
A-SMA
B-left gastric artery
SMA
T/F It traverses anterior to the PV
false
what is the size of a normal splenic vein?
under 10mm
T/F “Sinistral” is the term used for left sided-splenic vein thrombosis
true
T/F A sonographic sign that is useful in determining if a DVT is chronic would be the presence of collaterals-
true
Describe the sonographic appearance of chronic or “old clot”?
hyperechoic
calcified
thickened walls
atrophic vessel
T/F If the D-dimer assay is negative ,it is unlikely there is a DVT
true
primary varicose
Result of incompetent SFJ valve
secondary varicose
History of DVT/obstruction or incompetent deep venous valves
T/F Bowel disease, such as ulcerative colitis, increases your risk of DVT
true
Which of the following also increases the risk of DVT? A-Pregnancy B-Post partum period C-Oral contraceptives D-Cancer E-all of the above
all of the above
T/F ABI stands for: ankle brachial index
true
T/F ABI is a reliable tool for documenting the presence of lower extremity arterial disease-
true
T/F An ABI of > 0.9 is indicative of no hemodynamically significant stenosis-
true
