American Registry of Radiologic Technologists (ARRT) Practice Exam

The best approach to controlling voluntary motion during a radiologic procedure is to provide a careful explanation of the procedure to the patient. When patients understand what is expected of them, including why it is important to remain still, they are often more cooperative. Clear communication can alleviate anxiety and help patients feel more comfortable, ultimately leading to better adherence to instructions about motion during the imaging process.

While the use of sedatives might seem like an effective option to minimize motion, it is not practical in all situations and can introduce additional risks and complications. Monitoring vital signs is essential for overall patient safety but does not directly address the need for immobilization to prevent voluntary motion during the imaging procedure. Finally, positioning the patient on a flat surface can assist in achieving stability, but without an understanding or cooperation from the patient, it may not be sufficient to prevent voluntary movement. Hence, the effectiveness of clear communication in fostering patient cooperation makes it the most suitable method for controlling voluntary motion.
