ARDMS RVT Exam 2025 | 170 Vascular Ultrasound
Practice Questions with Verified Answers
1. What percentage of stenosis does NASCET recommend for carotid
endarterectomy?
>70% stenosis
>60% stenosis
>40% stenosis
>50% stenosis
2. What condition is indicated by the reversal of flow in the left vertebral
artery during a carotid Doppler examination?
Subclavian Steal Syndrome
Pulmonary Embolism
Peripheral Artery Disease
Deep Vein Thrombosis
3. What type of resistance is associated with the superior mesenteric artery
(SMA) waveform after a meal?
triphasic
high resistance
low resistance
biphasic
,4. Which of the following would be considered the best test for diagnosing a
suspected pulmonary embolism?
, chest radiograph (CXR)
electrocardiogram
computerized tomography pulmonary angiogram
pulmonary function test
5. Cause of varicose veins
genetic mutation
leaky venous valves
high blood pressure
high cholesterol
6. Intermittent claudication refers to:
a constant pain that is felt in the anterior compartment of the lower
leg
fluid buildup around the ankle joints while bearing weight
pedal pulse pressures that vacillate between strong and weak
pain that occurs in the lower extremities during walking and
disappears after stopping
7. List the branches of the external carotid artery and explain their significance
in vascular anatomy.
The ECA does not have any branches; it directly supplies the heart.
The ECA branches are primarily responsible for supplying blood to
the lower limbs.
, The branches of the ECA include the superior thyroid artery,
ascending pharyngeal artery, lingual artery, occipital artery, facial
artery, posterior auricular artery, maxillary artery, and superficial
temporal artery, which supply blood to various structures in the
head and neck.
The ECA has three main branches that supply the brain.
8. If a patient presents with calf vein thrombosis, how would the 15-20%
propagation rate influence your management plan?
It would suggest immediate surgical intervention.
It would require the patient to start anticoagulation therapy
immediately.
It would indicate no need for follow-up.
It would prompt closer monitoring for potential complications.
9. In a clinical scenario, if a patient presents with symptoms of swelling and
pain in the arm, and imaging reveals a nonocclusive thrombus in the axillary
vein, what would be the most appropriate next step in management?
Monitor the patient and consider anticoagulation therapy
Prescribe antibiotics for infection
Discharge the patient with no treatment
Perform immediate surgery to remove the thrombus
10. If a patient presents with symptoms of acute limb ischemia and a Doppler
ultrasound shows an intimal flap in the femoral artery, what would be the
most appropriate next step in management?
Physical therapy
