1. 1Before positioning a patient for a vascular ultrasound, a sonographer notices that the hands are visibly soiled. Which hand hygiene method should the sonographer use?

   1. A. Wash with plain soap and running water.
   2. B. Rub with an alcohol-based hand product.
   3. C. Wipe with a healthcare antiseptic hand wipe.
   4. D. Rub with a chlorhexidine hand preparation.

   Answer: A

   Explanation: CDC says, "Ensure that healthcare personnel perform hand hygiene with soap and water when hands are visibly soiled." Visible soil makes soap and water the indicated method before patient contact.

   Reference: CDC's Core Infection Prevention and Control Practices for Safe Healthcare Delivery in All Settings — 5a. Hand Hygiene

2. 2A vascular sonographer needs to distinguish two small reflectors lying one behind the other along the ultrasound beam. Which resolution property controls whether they can be separated?

   1. A. Axial resolution.
   2. B. Lateral resolution.
   3. C. Temporal resolution.
   4. D. Contrast resolution.

   Answer: A

   Explanation: AAPM defines axial resolution as "the minimum spacing of two reflectors along the axis of the ultrasound beam" at which they remain resolved. The two reflectors lie along that axis.

   Reference: AAPM Report No. 8: Pulse Echo Ultrasound Imaging Systems—Performance Tests and Criteria — Section 3, Definitions; Axial Resolution

3. 3During ultrasound surveillance of an abdominal aortic aneurysm, the sonographer measures the widest transverse diameter. Which caliper convention does the IAC vascular standard specify?

   1. A. Outer wall to outer wall
   2. B. Inner wall to inner wall
   3. C. Leading edge to leading edge
   4. D. Inner wall to outer wall

   Answer: A

   Explanation: IAC calls for the "single widest outer wall to outer wall diameter measurement" in a transverse view. The calipers therefore span the full outer aortic walls.

   Reference: IAC Standards and Guidelines for Vascular Testing Accreditation — Part B, Section 5B, Standard 5.9.6.1B, printed p. 52

4. 4A vascular sonographer must examine a patient whose skin is open at the planned contact site. Which personal protective equipment is specifically indicated for anticipated contact with that skin?

   1. A. A surgical mask worn throughout the scan.
   2. B. Gloves worn during the contact with skin.
   3. C. Eye protection worn during the contact.
   4. D. A gown worn during the contact with skin.

   Answer: B

   Explanation: CDC directs staff to "Wear gloves when it can be reasonably anticipated that contact with blood or other potentially infectious materials, mucous membranes, non-intact skin, potentially contaminated skin or contaminated equipment could occur." The planned contact with open skin meets that condition; the other items address different exposure routes.

5. 5While assessing a vascular transducer, a sonographer sees spurious echoes arising from regularly spaced array elements that send energy away from the main beam. Which beam phenomenon explains them?

   1. A. Grating lobes.
   2. B. The focal zone.
   3. C. The near field.
   4. D. The main lobe.

   Answer: A

   Explanation: AAPM defines grating lobes as "Ultrasonic transducer beam energy transmitted into a direction other than that of the main lobe of the beam, resulting from the transducer consisting of multiple, regularly spaced elements rather than a single element." That matches the array-element mechanism.

   Reference: AAPM Report No. 8: Pulse Echo Ultrasound Imaging Systems—Performance Tests and Criteria — Section 3, Definitions; Grating Lobes

6. 6A sonographer reviewing an abdominal aortic aneurysm has a long-axis image but needs the required transverse measurement plane. How should that plane intersect the aorta?

   1. A. Perpendicular to the aortic long axis
   2. B. Parallel to the aortic long axis
   3. C. Oblique to the aortic long axis
   4. D. Tangential to the aortic outer wall

   Answer: A

   Explanation: The IAC standard defines a "Transverse view (defined as perpendicular to the long axis of the aorta)". That plane avoids measuring along the elongated vessel axis.

   Reference: IAC Standards and Guidelines for Vascular Testing Accreditation — Part B, Section 5B, Standard 5.9.6.1B, printed p. 52

7. 7During an ultrasound-guided vascular procedure, splashes of blood could reach the sonographer's face. Which protection directly addresses this exposure?

   1. A. A mask paired with ordinary prescription glasses.
   2. B. Protective goggles paired with examination gloves.
   3. C. Protective eyewear with a mask, or a face shield.
   4. D. A fluid-resistant gown paired with a surgical mask.

   Answer: C

   Explanation: CDC states, "Use protective eyewear and a mask, or a face shield, to protect the mucous membranes of the eyes, nose and mouth during procedures and activities that could generate splashes or sprays of blood, body fluids, secretions and excretions." Ordinary glasses, goggles without nose-and-mouth protection, and gown plus mask without eye protection leave some facial mucosa exposed.

8. 8On a vascular transducer's beam profile, what is the region between the transducer face and the last axial pressure maximum called?

   1. A. Near field.
   2. B. Far field.
   3. C. Focal plane.
   4. D. Depth of focus.

   Answer: A

   Explanation: AAPM defines the near field as "The region of a transducer beam lying between the transducer and the position of the last axial pressure maxima." The described region is therefore the near field.

   Reference: AAPM Report No. 8: Pulse Echo Ultrasound Imaging Systems—Performance Tests and Criteria — Section 3, Definitions; Near Field

9. 9During surveillance after endovascular abdominal aortic aneurysm repair, the sonographer checks for an endoleak. Which region must be assessed for blood flow outside the endograft?

   1. A. The aneurysm sac outside the endograft
   2. B. The aortic lumen above the endograft
   3. C. The iliac limb inside the endograft
   4. D. The outflow vessel below the endograft

   Answer: A

   Explanation: The IAC standard includes "the aneurysm sac outside of the endograft, including documentation of blood flow (endoleak) if identified." Flow in that excluded sac indicates a potential endoleak.

   Reference: IAC Standards and Guidelines for Vascular Testing Accreditation — Part B, Section 5B, Standard 5.9.7.3B, printed p. 53

10. 10After scanning intact skin with an external vascular ultrasound transducer, a sonographer prepares it for the next patient. What level of disinfection does AIUM specify between patients?

    1. A. Low-level disinfection.
    2. B. Intermediate-level disinfection.
    3. C. High-level disinfection.
    4. D. Sterilization of the transducer.

    Answer: A

    Explanation: AIUM states, "Preparation of external transducers between patients requires a low-level disinfection (LLD) process." The question specifies an external transducer on intact skin, so the higher processing levels are not the prescribed level.
