Vascular 22 & 30 TEST QUESTIONS Flashcards
Ultrasound examination of veins prior to vascular access device placement includes
patency, diameter, location
Vascular access device placement using ultrasound guidance for the initial needle puncture is associated with what
decrease risk of non-target puncture
Ultrasound imaging for vascular access device placement:
portable option for targeting access sites
Ultrasound imaging for vascular access device placement may be used by
any credentialed clinician
Target vein of choice in the upper extremity for central vascular access device
basilic
A central vascular access device is indicative for all of these except
internal nutrition
The appropriate tip position for central vascular access device is
distal 3rd SVC
Which is true about the EJV
superficial and tortuous
Which of these complications may occur after accidental puncture of carotid artery
hematoma
Which access site is associated with the highest risk of infection
common femoral vein
Collateral veins:
enlarge in the setting of neighboring larger vein stenosis and thrombosis
Which of these comorbid conditions increase the risk of central vascular access device placement
thrombocytopenia
The blood flow rate in the distal 3rd SVC is estimated at what
<2000 mL/min
Which vein can be more commonly used in neonate/children for access device
GSV
Which is not a potential complication of central vascular access device placement
celiac artery injury
Hemodialysis access is usually placed as far distal as possible because it
preserves proximal portion for future use
Upper extremity is preferred over the lower extremity because it
provides for easier access
AV fistulas have 2 year primary rates of approximately what percentage
40-70%
Risk that may preclude the creation of a fistula include all of the following except
prior arterial access for another procedure
Which of the features is not included with documentation
number of valves
The minimum arterial diameter for fistula creation in maturation is greater than
2mm
The minimum venous diameter for fistula creation in maturation is greater than
2.5mm
In situations where the cephalic vein is unusable, which vein is then preferred
basilic
Because of the medial location of the basilic vein, it must be
transposed and juxtaposed to an artery in order to be used
How long does it take an AV fistula to mature
8-12 weeks
A stenosis that develops within the outflow vein segment of a fistula is most often the result of
intimal hyperplasia
When calculating volume flow, what is correct
large sample gate
Valves within the vein of a fistula
site of stenosis development
Normal PSV measurement in a well functioning fistula is going to be
150-300cm/s
Normal fistula volume flow measured by duplex should be greater than
800mL/min
