Final answer:
For a radiographic examination of the AC joints, the patient should be in an upright position, both sides should be imaged for comparison, and images should be made with and without weights.
Step-by-step explanation:
For a radiographic examination of the AC joints, the following are required:
- Patient examined in the upright position: This is important to ensure proper positioning and alignment of the AC joints for accurate imaging.
- Both sides imaged for comparison: It is necessary to image both AC joints to compare any abnormalities or differences between them.
- Images made with and without weights: Additional weight may be applied to the patient's arm during the imaging process to assess the stability and function of the AC joints.
Therefore, the correct answer is b. 1 and 3 only.
