Answer :
Final answer:
The correct positions to suspend breathing on expiration for radiographic imaging are AP lumbar spine, AP sacrum, and AP coccyx to minimize motion and ensure clear images. So, the correct option is a) AP lumbar spine, AP sacrum, AP coccyx.
Explanation:
The ONLY 3 positions we suspend breathing on expiration for radiographic procedures are a) AP lumbar spine, AP sacrum, AP coccyx. These positions are necessary to reduce movement that could blur the image, as the relaxation of the diaphragm on expiration allows for better immobilization of the area being imaged. The lumbar spine, sacrum, and coccyx are all positioned closer to the image receptor when the patient is lying on their back (anterior-posterior positioning). This may also minimize the radiation dose to the patient as opposed to imaging them in a standing position. In these AP projections, optimal imaging is achieved when the patient suspends breathing upon expiration, creating a clear image without the interference of respiratory motion.
