Final answer:
The scope of practice for a limited operator includes performing basic radiographic examinations and providing explanations of the procedure but does not include the use of contrast. Answer C is correct.
Step-by-step explanation:
The scope of practice for a limited operator primarily includes performing basic radiographic examinations. It does not usually encompass the administration of contrast media, which is often handled by more highly qualified radiologic technologists or directly under the supervision of a physician. Moreover, while they can give a simple explanation of the procedure, in-depth discussions about the diagnostic process or the interpretation of results should be provided by the radiologist or physician. Therefore, the correct answer is C. 2 and 3 only. In modern medical imaging, the X-ray continues to be widely used for viewing fractures and dental assessments. However, technological advancements have introduced sophisticated techniques such as computed tomography (CT), which takes multiple X-ray measurements to produce cross-sectional views. These developments have extended the capabilities of medical imaging far beyond the simple X-ray.
