2) Air or fluid levels are seen.
3) Engorgement of the pulmonary vessels is also avoided.
How far should the upper border of the IR be above the relaxed shoulders?
1 1/2 to 2 inches
On a PA what should be centered to the midline of the IR?
The midsagittal plane of the patient's body
What do you do with the chin?
Extend it upward so that it does not interfere with the xray.
Why do you flex the arms and rest them on the back of the hips?
This rotates the scapulae laterally so that they are not superimposed over the lungs.

What ways will the lungs expand?

The second breath on full inspiration.
How many ribs should show above the diafrom the diaphragm?
What part of the lungs should show in a radiograph?
