Question

16 multiple choice 1 point why would the chest most likely be demonstrated using two pa projections (in which the patient is seen in suspended inspiration and suspended expiration)? to demonstrate pneumothorax to evaluate the heart and great vessels to measure the width of the mediastinum to demonstrate movement of the diaphragm 17 multiple choice 1 point which of the following is an effective way to detect rotation of the patient with the pa projection image of the chest? the number of ribs demonstrated above the diaphragm the asymmetric appearance of the sternoclavicular joints the amount of apical area demonstrated above the clavicles

Explanation:

For question 16, PA projections in suspended inspiration and expiration are used to evaluate the heart and great vessels as changes in the thoracic cavity during breathing can affect their appearance. For question 17, rotation in a PA projection of the chest can be detected by assessing the symmetry of the ribs above the diaphragm, the amount of apical area demonstrated above the clavicles, and the sternoclavicular joints' appearance.

Answer:

1. To evaluate the heart and great vessels
2. The number of ribs demonstrated above the diaphragm, the amount of apical area demonstrated above the clavicles, The asymmetric appearance of the sternoclavicular joints
