Exam Questions Chapter 11-13 Flashcards
What is the correct set regarding the causes of Raynauds Syndrome?
a. 40% connective tissue disorder, 20% idiopathic, 40% miscellaneous
b. 40% Arterial disorder, 20% idiopathic, 40% miscellaneous
c. 40% connective tissue disorder, 40% idiopathic, 20% miscellaneous
d. 40% Arterial disorder, 40% idiopathic, 20% miscellaneous
C. To answer this question you needed to know the correct causes of Raynauds syndrome + their corresponding percentages.
When performing a pre-operative assessment to determine vessel suitability to revascularize the leg with a femoro-popliteal or femoro-tibial bypass graft which of the following would be a contraindication?
A. GSV is being used as a collateral pathway
B. GSV diameter of 2.5 mm
C. Continuous GSV
D. The GSV is duplicated
A. GSV is being used as a collateral pathway
What is a normal Digit Brachial Pressure for upper extremity?
A) < .66
B) > .7 - 1.3
C) < .3
D) > .9 - 1.3
B. The other answers A,C, and D are lower extremity ABI or TBI
When monitoring limbs for potential Thoracic Outlet Syndrome, a significant and sustained decrease in amplitde suggests what?
A. Vascular Compression
B. Small Vessel Occlusive Disease
C. Vasospasm
D. Vasodilation
A. Vascular Compression
A patient presents with complaints about numbness, loss of function, and whitening of the fingertips when exposed to the bitter Chicago cold. This digital vasospasm is often induced by cold exposure or vibration injury and can even affect the toes. This is called ____________.
A. Buerger’s Disease
B. Thoracic Outlet Syndrome (TOS)
C. Raynaud’s Phenomenon
D. Marfan Syndrome
C. Raynaud’s Phenomenon
Using the image below: What diagnosis could this flow pattern be associated with?
1. Aneurysm
2. Arteriovenous Fistula
3. Pseudoaneurysm
4. Severe Stenosis (>75%)
Pseudoaneurysm, This flow pattern is called “to and fro flow
what is a disadvantage of using a synthetic bypass graft?
A. they are not readily available
B. it has an increased risk of graft failure
C. the walls are very hard to see and evaluate in ultrasound evaluation
D.very flexible so its not stable and it can shift around
B. theres a higher chance of graft failure in synthethic bypass grafts than with autogenous grafts
What is not an advantage of a Radial Artery harvest?
A) Thicker walls
B)Reduced risk of hyperplasia
C) Newer flexible placement through adductor canal
D) Better availability
C. newer flexible placement adductor canal. This is an advantage of a sytheitc bypass graft.
If a patient has an aneyrysm of a popliteal artery, what two other locations are likely to present with aneurysms?
A. A proximal popliteal artery aneurysm, and an abdominal aortic aneurysm
B. A contralateral femoral artery aneurysm and a carotid artery aneurysm
C. A contralateral popliteal artery aneurysm as well as an abdominal aortic aneurysm
D. An ipsilateral femoral artery aneurysm as well as a subclavian artery aneurysm
C. A contralateral popliteal artery aneurysm as well as an abdominal aortic aneurysm
What is the difference between the usage of Parks Flo vs. Color Duplex?
A) There is no difference between the two
B) Parks flo is able to identify the exact location of occlusive disease whereas color duplex can only identify the region of area
C) Parks flo only shows a region of area whereas color duplex identifies the exact location of occlusive disease
D) Parks flo can only identify segmental pressures and not occlusive disease whereas color duplex can only identify occlusive disease
C. Parks flo only shows a region of area where the cuffs shows segmental pressure differences. In color duplex, you are able to follow the anatomy and see where the occlusive disease may be.
While testing Palmar Arch patency, if all the PPG waveforms drop to flat-line or nearly flat-line with radial artery compression, the patient is _______ and a radial artery harvest is contraindicated.
À Ulnar dominate
B Mixed dominate
C Radial dominate
D Brachial dominate
C) Radial dominate because this indicates that the Ulnar artery cannot supply sufficient blood flow to the hand and digits.
When performing a digital evaluation for Raynaud’s using Test B, we need to ensure the patient is not experiencing vasoconstriction or vasospasm. What prep do we need to do before recording PVRs or PPGs?
A. Remove PPG sensors and place the symptomatic hand in a plastic bag and submerge it in ice water for 1-2 minutes
B. Wrap the asymptomatic hand in an electric heating pad and warm the hand for 5 minutes
C. Ensure the exam room is warm
D. Ensure the exam room is cold
C. Ensure the exam room is warm
During pre-op assessment for radial artery harvest (CABG) we have to make sure that patient has:
a) mixed dominance
b) ulnar dominance
c) radial dominance
d) complete palmar arch
If the radial artery is removed in a patient that is“radial dominant”, and if the palmar arch is not intact, severe ischemia may result in the fingers and hand. Therefore, the correct answer is answer “d.”
What is a contraindication to performing an arterial bypass graft ?
a. If the patient has had prior surgeries in the same area
b. If the GSV is greater than 2.5mm
c. If the popliteal artery has an occlusion
d. If the GSV is being used as a collateral vessel
d. If the GSV is being used as a collateral vessel
When performing a PPG digit,
of the following is a correct placement of the sensors?
*Ring finger is number 2
* Index finger is number 4
* Thumb is number 5
* Pinky is number 5
D: pinky finger is number 5
