A patient receives an X-ray after being in a sports-related accident. What kind of healthcare activity is this?

Receiving an X-ray after a sports-related accident is primarily associated with injury detection. This process involves imaging technology to evaluate and diagnose injuries that may not be visible through physical examination alone, such as fractures or internal damage. X-rays allow healthcare professionals to assess the extent of any injuries sustained during the accident, which is crucial for determining appropriate treatment.

While health assessment refers to a broader evaluation of a patient's overall health status, and emergency care pertains to immediate treatment needed in response to a traumatic incident, the key focus of the X-ray is to identify specific injuries. Health promotion generally involves activities to improve health and prevent disease, which is not the primary goal in this scenario. Therefore, the correct classification of the activity related to receiving an X-ray after an accident is injury detection.
