Question

29 multiple choice 1 point which evaluation criterion pertains to the pa projection image of the chest? the ribs should appear distorted. the sternum should be lateral, not rotated. ten posterior ribs should be visible above the diaphragm. the ribs posterior to the vertebral column should be superimposed. 30 multiple choice 1 point which evaluation criterion pertains to the pa projection image of the chest? the ribs should appear distorted. the clavicles should lie superior to the apices. the scapulae should be projected outside the lung fields. the ribs posterior to the vertebral column should be superimposed.

Explanation:

In a PA (postero - anterior) projection image of the chest, the scapulae should be projected outside the lung fields to avoid obscuring lung details. The ribs should not be distorted, the sternum should be mid - line (not lateral), and typically 10 posterior ribs are visible above the diaphragm, but the key correct criterion among the options for chest PA projection is the scapulae position. For the second question, the scapulae being projected outside the lung fields is a key evaluation criterion for a proper PA chest projection.

Answer:

1. The scapulae should be projected outside the lung fields.
2. The scapulae should be projected outside the lung fields.
