Which pairing correctly matches the injury types to their time frame?

• A. Specific injury arises from a single incident; Cumulative injury arises from repetitive trauma
• B. Specific injury arises from repetitive trauma; Cumulative injury arises from a single incident
• C. Specific injury arises from a single incident; Cumulative injury arises from a single incident
• D. Neither

Answer: (A)

Injury types are defined by how they occur over time. A specific injury arises from a single identifiable incident, while a cumulative injury develops from repetitive trauma over a period. This pairing is correct because it assigns a single-event mechanism to a specific injury and a multi-event, time-spread mechanism to a cumulative injury. The other options mix up the mechanisms or suggest both injuries come from the same pattern, which isn’t accurate. For example, a fall causing a fracture is a specific injury, while carpal tunnel from repeated keyboard use is a cumulative injury.
