CCI RVS review (Answered) 100%
Correct. 60 Questions and Correct
Answers. Latest 2024/2025.
Lateral resolution is related to
The spacing of reflectors perpendicular to the beam
When using Doppler ultrasound, what is proportional to the amount of absorption and determines
the depth of penetration?
Frequency of the transmitted ultrasound
If the frequency of the transducer increases, the wavelength
Decreases
Clinical manifestations of portal hypertension include (3)
-splenomegaly
-encephalopathy
-Ascites
What symptoms suggest compromised circulation in the vertebrobasilar system? (3)
-drop attacks
-ataxia
-diplopia
Atherosclerosis and embolus are common causes of
Ischemic stroke
A low pitched bruit heard low on the right neck, radiating up o the right carotid and out over the
supraclavicular fossa most likely represents a lesion in what artery
Brachiocephalic aka Innominate artery (ps only one brachiocephalic artery and it's on the right side)
Post-thrombotic disease manifested by stasis dermititis, ulceration, secondary varicose veins and
varying degrees of lower extremity edema are usually due to
Valvular insufficiency
Optimal patient positioning for evaluation of DVT in the lower extremities Is
Reverse trendelenburgh (heart above legs)
When using PPG to examine for GSV incompetence, the pt should be
Sitting upright with a tourniquet applied just below the knee
A leg ulcer has an irregular edge, pink-red base, surrounding pigmentation and associated mild pain
is most likely due to
, Venous stasis
What are the results of the valsalva maneuver
Decreased venous return to the heart
Patients who present with rest pain sometimes complain of increased pain while sleeping. This is a
result of
Lower cardiac output
Why are arterioles the primary site for determining peripheral resistance?
Because of their crosse sectional area
The area of the body known as the "peripheral heart" is the
Calf muscles (soleol / skeletal muscle pump)
What mechanism is primarily responsible for returning blood to the heart while walking?
Skeletal muscle
In theory, when interrogating laminar arterial flow, the blood velocity is
Faster in center stream
Changes in velocity and direction of blood flow will have the greatest effect on
Energy loss due to inertia
Considering normal anatomy of the distal lower extremities, how many deep veins typically
accompany each major artery?
Two
What is the relationship between frequency and absorption?
Directly related
What determines the depth of penetration?
Frequency
The higher the frequency the _____ the absorption
Higher (and vice Versa)
The lower the frequency, the _____ the penetration
Deeper (and vice Versa)
Portal hypertension brings blood back to what two veins?
Superior mesenteric and splenic
Secondary veins indicate there are both
Superficial AND deep
Post thrombotic indicates
