FREE SPI
PRACTICE TEST (2023)

Are you prepared for your exam? Our free practice test contains real-life questions to help you find out.

OUR STUDY GUIDE FOLLOWS NEW SPI CONTENT OUTLINE THAT WAS PUBLISHED ON SEPTEMBER 1, 2023.

There’s only one thing standing between you and an exciting career as an ultrasound technician: your SPI exam!

We use actual questions that appear on the written portion of the SPI exam, so our practice test will help you discover if you’re definitely prepared for the real thing!

The SPI examination assesses the knowledge, skills, and abilities in the areas of clinical safety, physical principles, pulsed echo instrumentation, and quality assurance. The exam meets the fundamental physical principles and instrumentation requirements for the RDMS, RDCS, RVT, and RMSKS credentials.

Our free practice test (below) helps you prepare for and pass the written portion of the exam: it contains 15 questions, all of which are representative of the questions that appear on the real thing.

- Overly intense acoustic signals
- Attenuation
A sonographer is assisting with a core needle biopsy. During a biopsy pass, reflections are created at increasing depths, deep to the core biopsy needle. These reflections refer to an artifact called:*
- Mirror image
- Refraction
- Reverberation
- Focal banding
Sound is redirected in a single, uniform direction when it encounters which type of reflector?*
- Rough
- Specular
- Diffuse
- Rayleigh
A sonographer performing an abdominal ultrasound narrows the sector width. Which of the following is affected?*
