  1. Which radiographic view is best for evaluating the trachea and mainstem bronchi in a dog?

    Answer: Lateral

    The lateral view superimposes the trachea and mainstem bronchi in profile, making them easiest to evaluate without superimposition of other structures.

  2. What is the primary safety concern when performing radiographs on a patient with suspected pneumothorax?

    Answer: Patient positioning stress exacerbating dyspnea

    Patients with pneumothorax are already dyspneic, and the stress and positioning required for radiography can worsen respiratory compromise or cause decompensation.

  3. On ultrasound, which tissue characteristic causes acoustic shadowing?

    Answer: Highly attenuating or reflective materials such as calculi or bone

    Calculi, bone, and other highly reflective or attenuating materials block the ultrasound beam, creating a dark shadow artifact distal to the object.

  4. A radiograph shows increased opacity in the lung fields with an air bronchogram sign. This finding is MOST consistent with:

    Answer: Alveolar lung disease

    Air bronchograms form when fluid or soft tissue fills the alveoli but air remains in the bronchi, creating a visible bronchial pattern — classic for alveolar (consolidating) lung disease.

  5. When positioning a patient for a VD (ventrodorsal) thoracic radiograph, the beam enters from:

    Answer: Ventral to dorsal

    In a VD projection the X-ray beam enters the ventral (belly) side first and exits the dorsal side, with the patient in dorsal recumbency.

  6. Which of the following BEST describes the Doppler ultrasound technique used to assess blood flow direction?

    Answer: Color flow Doppler

    Color flow Doppler encodes the direction and relative velocity of blood flow as color (typically red toward and blue away from the transducer) overlaid on the B-mode image.

  7. What kVp range is typically used for thoracic radiography in a medium-sized dog?

    Answer: 70–85 kVp

    Thoracic radiography in medium dogs typically uses 70–85 kVp to provide adequate penetration through the chest wall while maintaining sufficient contrast.
