Click on your answer to each question and then click on "score quiz." Your test will be automatically scored. You must score 70% or better to pass. If you pass, simply fill in the information form and your certificate will be ready for printing.


1. The most frequent access path is via the

femoral artery

axillary artery

abdominal aorta

carotid artery


2. Generally complications happen after puncture within the range of:

less than 0.01 %

0.1- 9 %

9-15 %

more than 15 %


3. Which complication is extremely rare?:

heart attack

arteriovenous fistula

dissection

pseudoaneurysm


4. B-Mode is an ultrasound technique where structures are displayed as

lines

quads

quads and lines

dots


5. Imaging with B-Flow is similar to

digital subtraction angiography

CT

MRI

conventional x-ray


6. B-Flow after percutaneous catheter procedures is not useful in imaging of:

AV fistula

dissection

pseudoaneurysm

hematoma


7. Pseudoaneurysm

is not a pulsatile mass.

has no risk of rupture.

could be a result from missing closure after puncture.

has no pendulum flow in the aneurysm neck.


8. AV Fistula

is a pathological shunt.

never reduces the peripheral vessel resistance.

never shows a tendency to increase in size.

never occludes spontaneously.


9. The best visual information in femoral artery dissection is given by

B-Mode

Color Coded Duplex Sonography

B-Flow

Power Doppler


10. Dissections

are never seen in B-Mode

do not depend on the direction of puncturing

never need surgical therapy

are presented in the literature with a prevalence of 0.3-6%
