Final answer:
All the options provided, including severe pain, massive internal bleeding, and shock, can be symptoms that accompany a pelvic injury.
Step-by-step explanation:
The question asks about symptoms that may accompany a pelvic injury. A pelvic injury can lead to several serious symptoms, including severe pain, which is the body's natural response to injury. In addition, an injury to the pelvis can cause massive internal bleeding because of the bone's proximity to major blood vessels. This bleeding can, in turn, lead to another symptom, shock, specifically hypovolemic shock, which is a type of circulatory shock caused by excessive loss of blood volume. Therefore, the correct response to the question would be that all of the answered options are symptoms that can accompany a pelvic injury.
