Question

21 multiple choice 1 point which pa oblique projection of the chest may be used to evaluate the heart and great vessels when performing a cardiac series? 45 - degree rao 45 - degree lap 55 - to 60 - degree lao 10 - to 20 - degrees rao and lao 22 multiple choice 1 point how many degrees should the patient be rotated for pa oblique projections of the chest to evaluate the lungs? rao: 45 degrees; lao 45 degrees b.rao: 45 degrees; lao 55 to 60 degrees c.rao: 55 to 60 degrees; lao 45 degrees d.rao 55 to 60 degrees; lao 55 to degrees

Explanation:

1. For evaluating the heart and great vessels in a cardiac series using a PA oblique projection, a 55 - to 60 - degree LAO (left anterior oblique) is commonly used as it provides a good view of the heart's chambers and great vessels.
2. For PA oblique projections of the chest to evaluate the lungs, RAO (right anterior oblique) and LAO (left anterior oblique) are typically 45 degrees each to best visualize the lung fields and their structures.

Answer:

1. C. 55 - to 60 - degree LAO
2. A. RAO: 45 degrees; LAO 45 degrees
