RVT ARDMS Exam 2025 150 Vascular Ultrasound
Questions with Accurate Answers
1. Describe the process involved in performing a pulmonary angiography.
The patient is placed under anesthesia before the catheterization.
An IV is inserted, and images are taken without contrast.
A catheter is advanced through veins to the right atrium and into
the pulmonary artery, where contrast is injected and images are
taken.
Blood samples are drawn before the procedure.
2. Why is the D-dimer test considered to lack specificity?
Because D-dimer can be elevated in various conditions unrelated
to thrombosis.
Because D-dimer is a direct measure of clot formation.
Because D-dimer levels are always normal in healthy individuals.
Because D-dimer is only elevated in cases of deep vein thrombosis.
3. Describe the significance of the brachiocephalic vein in the venous system.
The brachiocephalic vein carries blood from the heart to the body.
The brachiocephalic vein is responsible for oxygenating blood in the
lungs.
The brachiocephalic vein is significant as it collects blood from the
,upper limbs and head, directing it towards the superior vena cava.
The brachiocephalic vein is involved in the filtration of blood in the
kidneys.
,4. Describe a potential risk involved with the use of contrast medium in
pulmonary angiography.
An allergic reaction to contrast medium can occur during
pulmonary angiography.
It may lead to increased blood pressure.
The procedure can cause chronic cough.
The procedure can result in permanent lung damage.
5. All of the following are limitations of venography EXCEPT it:
cannot image multiple limbs in the same patient at the same time
may result in thrombophlebitis
cannot define adjacent arterial structures
gives little information regarding vein wall thickness
does not accurately identify vein wall calcification's
6. Describe how ascending venography is utilized in diagnosing venous
diseases.
Ascending venography helps in assessing heart valve function.
Ascending venography is used to measure blood flow in the
arteries.
Ascending venography is primarily for diagnosing respiratory
conditions.
Ascending venography is utilized to visualize the veins from distal
to proximal, allowing for the detection of abnormalities such as
deep vein thrombosis (DVT).
, 7. Describe how the site of obstruction in Budd-Chiari syndrome can affect
the condition's presentation.
The obstruction only occurs in the IVC and does not affect the
hepatic veins.
Obstruction at the hepatic vein level always results in the same
symptoms regardless of location.
The site of obstruction can vary, affecting blood flow and leading
to different symptoms based on whether the obstruction is at the
hepatic vein level, sinusoids, or IVC.
The symptoms are uniform regardless of the site of obstruction.
8. Thrombosis of the ilio-femoral venous segments resulting in massive lower
extremity swelling describes
primary varicose veins
chronic deep venous thrombosis
phlegmasia cerulea dolens
post-phlebitic syndrome
9. What is the primary purpose of ascending venography?
To assess arterial blood flow in the limbs.
To measure blood pressure in the arteries.
To evaluate the function of the heart valves.
To image the veins from distal to proximal and detect venous
abnormalities including DVT.
10. If a 35-year-old male athlete presents with symptoms of claudication,
which vascular disease should be considered based on demographic
