Question 1

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

Accepted Answer

Lateral

Answer

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

Question 2

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

Accepted Answer

Patient positioning stress exacerbating dyspnea

Answer

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

Question 3

On ultrasound, which tissue characteristic causes acoustic shadowing?

Accepted Answer

Highly attenuating or reflective materials such as calculi or bone

Answer

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

Question 4

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

Accepted Answer

Alveolar lung disease

Answer

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.

Question 5

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

Accepted Answer

Ventral to dorsal

Answer

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.
