RVT - Registered Vascular Technologist Quality Assurance and Safety Questions and Answers

Question 1

A technologist is called to the ICU for a stat lower extremity venous duplex to rule out DVT on a patient who is intubated and sedated.
Which of the following is the most critical first step before starting the examination?

Accepted Answer

Confirm the patient's identity using at least two identifiers from the patient's wristband.

Answer

Ask the nurse to verbally confirm the patient's name and the correct leg to be scanned.

Answer

Immediately begin scanning the symptomatic leg to ensure the exam is completed as quickly as possible.

Answer

Review the patient's prior imaging studies on the PACS system to understand their history.

Question 2

A sonographer reports frequent right shoulder and neck pain. Which of the following is the most effective ergonomic practice to mitigate the risk of a work-related musculoskeletal disorder (WRMSD)?

Accepted Answer

Adjusting the exam table and chair so the scanning arm's angle of abduction is less than 30 degrees.

Answer

Gripping the transducer with increased force to maintain better control.

Answer

Performing the majority of exams while standing to improve posture and core strength.

Answer

Scheduling similar exam types back-to-back to improve efficiency.

Question 3

Accepted Answer

Thermal Index for cranial bone (TIC)

Answer

Mechanical Index (MI)

Answer

Thermal Index for bone (TIB)

Answer
