1. Which of the following can result in a false-positive diagnosis of
DVT?
A. Chronic venous insufficiency b) Large lymph nodes c)
Arteriovenous malformation d) Calcified veins Answer: b) Large
lymph nodes Rationale: Enlarged lymph nodes near veins can
mimic the appearance of a DVT on ultrasound.
2. What is the normal response of peripheral arteries to exercise?
A. Increased resistance b) Decreased resistance c) Decreased flow
velocity d) Reversed flow Answer: b) Decreased resistance
Rationale: Exercise causes vasodilation, reducing resistance and
increasing blood flow.
3. Which vessel is primarily responsible for venous return from
the brain?
A. Subclavian vein b) Brachiocephalic vein c) Jugular vein d)
Vertebral vein Answer: c) Jugular vein Rationale: The internal
jugular vein is the primary pathway for venous return from the
brain.
4. Which type of Doppler imaging provides velocity information
at a specific point?
,A. Continuous wave Doppler b) Pulsed wave Doppler c) Color
Doppler d) Power Doppler Answer: b) Pulsed wave Doppler
Rationale: Pulsed wave Doppler provides velocity measurements
from a defined sample volume.
5. What is the purpose of a reverse Trendelenburg position during
venous duplex imaging?
A. To compress the deep veins b) To dilate the superficial veins c)
To reduce patient discomfort d) To improve arterial visualization
Answer: b) To dilate the superficial veins Rationale: Reverse
Trendelenburg promotes venous pooling, which aids in evaluating
venous insufficiency.
6. Which of the following vessels is not typically evaluated during
lower extremity arterial duplex?
A. Superficial femoral artery b) Common femoral artery c) Radial
artery d) Popliteal artery Answer: c) Radial artery Rationale: The
radial artery is located in the upper extremity and not part of the
lower extremity arterial study.
7. Which artery supplies the majority of the brain's blood flow?
A. Vertebral artery b) Middle cerebral artery c) Anterior cerebral
artery d) Posterior cerebral artery Answer: b) Middle cerebral
artery Rationale: The middle cerebral artery supplies the largest
portion of the cerebral cortex.
, 8. What is the diagnostic imaging method for deep vein
thrombosis (DVT)?
A. CT angiography b) Venous duplex ultrasound c) MRI d)
Plethysmography Answer: b) Venous duplex ultrasound
Rationale: Ultrasound is the gold standard for diagnosing DVT
due to its non-invasive nature and high accuracy.
9. Which vein is commonly involved in May-Thurner syndrome?
A. Great saphenous vein b) Left common iliac vein c) Right
femoral vein d) Popliteal vein Answer: b) Left common iliac vein
Rationale: May-Thurner syndrome involves compression of the
left common iliac vein by the right common iliac artery.
10. Which test is commonly used to evaluate arterial inflow to the
digits?
A. Photoplethysmography b) Duplex ultrasound c) Segmental
pressure measurement d) ABI Answer: a) Photoplethysmography
Rationale: Photoplethysmography evaluates microvascular
perfusion and arterial inflow in digits.
11. What is the primary diagnostic criterion for >70% stenosis in
a carotid artery?
A. Peak systolic velocity (PSV) >125 cm/s b) End-diastolic
velocity (EDV) >40 cm/s c) Peak systolic velocity (PSV) >230
cm/s d) ICA/CCA ratio <2.0 Answer: c) Peak systolic velocity
DVT?
A. Chronic venous insufficiency b) Large lymph nodes c)
Arteriovenous malformation d) Calcified veins Answer: b) Large
lymph nodes Rationale: Enlarged lymph nodes near veins can
mimic the appearance of a DVT on ultrasound.
