Final answer:
The patient should be rotated approximately 60 degrees for the PA oblique sternum projection. Therefore the correct answer is option (D)
Step-by-step explanation:
The correct answer is d. 60°.
For the PA oblique sternum projection, the patient should be rotated approximately 60 degrees. This angle helps to visualize the sternum in a more oblique position, allowing for better visualization of certain anatomical structures.
It is important to note that the specific angle of rotation can vary slightly depending on the patient's body characteristics and the imaging facility's protocols.
