An AP thoracic projection with poor positioning demonstrates closed eighth through twelfth in-tervertebral disk spaces. How was the patient mispositioned for such a projection to be obtained?
a. The patient was rotated toward the left side.
b. The patient's knees and hips were extended.
c. The long axis of the vertebral column was laterally tilted.
d. The patient's head was on a thick pillow.
Question 2

3. spinous processes aligned with the midline of the vertebra bodies.
4. open intervertebral joint spaces.
a. 1 and 4 only
b. 2 and 3 only
c. 2, 3, and 4 only
