Final answer:
The type of pain addressed in a patient with an ulnar fracture from a motor vehicle accident is acute pain, which arises immediately after tissue damage and usually lasts until healing.
Step-by-step explanation:
When addressing a patient in the emergency department (ED) who has sustained an ulnar fracture from a motor vehicle accident, the type of pain you would be addressing is acute pain. Acute pain is the immediate and often intense physical discomfort that arises from tissue damage, in this case, the damage associated with a broken bone. It is an immediate response to injury and typically lasts until the fracture heals.
