RVT Evaluation Content and Format 3 — Questions and Answers
Question 1: Which cerebrovascular evaluation technique assesses blood flow within the circle of Willis and intracranial vessels?
- Carotid duplex
- Transcranial Doppler (TCD) (Correct answer)
- Ophthalmodynamometry
- Vertebral duplex
Correct answer: Transcranial Doppler (TCD)
Transcranial Doppler (TCD) uses low-frequency ultrasound transmitted through acoustic windows to evaluate intracranial vessels including the circle of Willis.
Question 2: In the context of RVT exam content, what does the term 'physiologic testing' refer to?
- Laboratory blood flow simulations
- Non-imaging tests such as ABI and segmental pressures (Correct answer)
- Histological analysis of vessel walls
- Pharmacological stress testing
Correct answer: Non-imaging tests such as ABI and segmental pressures
Physiologic testing refers to non-imaging vascular tests such as ankle-brachial index (ABI) and segmental limb pressures that assess hemodynamic status.
Question 3: Which domain of the RVT examination specifically covers the candidate's ability to recognize artifacts and technical limitations?
- Clinical indications
- Instrumentation and physics (Correct answer)
- Patient care and safety
- Billing and documentation
Correct answer: Instrumentation and physics
The instrumentation and physics domain covers ultrasound artifacts, equipment settings, and technical limitations relevant to vascular imaging.
Question 4: What is the standard format for questions on the ARDMS RVT examination?
- True/false questions with brief justifications
- Single-best-answer multiple choice with four options (Correct answer)
- Matching questions pairing diagnoses with waveforms
- Extended matching with up to eight answer options
Correct answer: Single-best-answer multiple choice with four options
The RVT examination uses single-best-answer multiple choice questions, each with four answer options, consistent with standardized credentialing exam formats.
Question 5: Which type of examination question on the RVT exam would most likely present a patient scenario followed by ultrasound findings requiring diagnosis?
- Recall question
- Comprehension question
- Application/clinical scenario question (Correct answer)
- Calculation question
Correct answer: Application/clinical scenario question
Application/clinical scenario questions present patient history and imaging findings, requiring the candidate to integrate knowledge and select the correct diagnosis or action.
Question 6: A vascular technologist is preparing for the RVT exam and wants to review lower extremity arterial content. Which evaluation should receive the most study time?
- Penile blood flow assessment
- Segmental pressure and duplex evaluation of the lower extremity arteries (Correct answer)
- Toe photoplethysmography only
- Iliac vein compression assessment
Correct answer: Segmental pressure and duplex evaluation of the lower extremity arteries
Lower extremity arterial evaluation including segmental pressures and duplex scanning is the highest-weighted component of the peripheral arterial section.
Question 7: The RVT exam content outline is maintained and updated by which organization?
- American College of Radiology (ACR)
- American Registry for Diagnostic Medical Sonography (ARDMS) (Correct answer)
- Society for Vascular Surgery (SVS)
- American Heart Association (AHA)
Correct answer: American Registry for Diagnostic Medical Sonography (ARDMS)
ARDMS develops and maintains the RVT examination content outline, which undergoes periodic practice analysis to ensure clinical relevance.
