Exam #3, things you keep missing

Question 1

Superior Cerebellar Artery, where is it

Answer 1

visualize, revisit diagram

Question 2

hemodynamically significant lesions do what

Answer 2

restrict flow

Question 3

thromboembolic plaque does what

Answer 3

sends small clots into the distal circulation

Question 4

not the residual lumen but the

Answer 4

true lumen

Question 5

common site of stenosis

Answer 5

carotid bifurcation

Question 6

DVT of the lower extremity would have us concerned about venous circulation. why?

Answer 6

pulmonary embolism (possibility of)

Question 7

soft, fibrous plaque is darker or lighter than other types of plaque

Answer 7

darker!

Question 8

tunica externa or tunic media, which is thicker?

Answer 8

media
remember function dictates form

Question 9

the tunica media and the tunica external BOTH have smooth muscle fibers…. true or false?

Answer 9

TRUE!

Question 10

Celiac artery (trunk) off the abdominal aorta branches into what arteries. These arteries feed what?

Answer 10

1. branches into left gastric, splenic, and common hepatic arteries.
2. feeds the stomach, liver, pancreas, duodenum, and spleen.

Question 11

superior mesenteric artery feeds what

Answer 11

small intestine, cecum, ascending colon, part of the transverse colon

Question 12

left and right renal arteries supply blood to what

Answer 12

kidneys, suprarenal glands, ureters

Question 13

inferior mesenteric artery supplies blood to

Answer 13

left half of transverse colon, the descending, iliac, and sigmoid colon and part of the rectum. Comes off 3-4 cm above the aortic bifurcation

Question 14

at what junction does the common iliac artery divide in the internal and external iliac arteries

Answer 14

lumbosacral junction

Question 15

when artery does the external iliac artery become?

Answer 15

common femoral artery

Question 16

subclavian artery becomes what artery and where

Answer 16

becomes axillary artery at outer border of 1st rib

Question 17

axillary artery becomes what artery

Answer 17

brachial artery

Question 18

brachial artery bifurcates into what arteries

Answer 18

radial and ulnar artery

Question 19

volar arch aka

Answer 19

superficial palmar arch

Question 20

ICA branches and blood supply

Answer 20

gives off first branch, ophthalmic artery after it passes into the skull.

then gives off anterior choroidal artery, posterior communicating artery, finally dividing into middle cerebral artery and anterior cerebral artery

supplies blood to anterior brain, eyes, forehead, and nose

Question 21

ECA branches and blood supply

Answer 21

gives off 8 branches (branches BEFORE enters skull, as opposed to ICA).

supplies blood to neck, face, scalp.

comes off subclavian arteries and unite to form basilar artery after they enter skull through foramen magnum

Question 22

because of effects of venous thrombosis, increased venous pressure from gravity, increased intraabdominal pressure, and venous obstruction in the lower extremities, WHAT is more prone to disease

Answer 22

Valves in the lower extremities

Question 23

the common carotid, internal carotid, and external carotid all have what type of waveforms?

Answer 23

monophonic waveforms

Question 24

In a lower extremity arterial exam, BOTH legs are evaluated. True or False?

Answer 24

TRUE, both arterial systems are examined

Question 25

main method used for evaluation of bypass grants or pseudo aneurysms of LEA systems

Answer 25

Duplex evaluation (direct evaluation) would include: actual images (transverse and longitudinal) of blood vessel while using color flow and PW Doppler

Question 26

this type of testing uses blood pressure cuff measurements and Doppler waveforms only *NO ACTUAL IMAGES*

Answer 26

indirect arterial evaluation

Question 27

This type of testing can evaluate collateral circulation

Answer 27

INDIRECT arterial evaluation (even though NO ACTUAL IMAGES!*)

Question 28

lower extremity venous evaluation concententrates on SUPERFICIAL or DEEP venous system

Answer 28

DEEP VENOUS SYSTEM to detect DEEP VEIN THROMBOSIS (DVT)

Question 29

Veins are compressed to prove the absence of clots. TRUE or FALSE

Answer 29

TRUE!
