Which statement about MOI and injury severity is accurate?

• A. The MOI may allow you to predict the severity of injuries.
• B. The exact location of injuries can be determined by MOI.
• C. A nonsignificant MOI rules out the possibility of serious trauma.
• D. A significant MOI always results in patient death or permanent disability.

Answer: (B)

Mechanism of injury informs you about the energy transfer involved and helps you anticipate what kinds of injuries and how severe they might be. It guides your assessment, triage, and the questions you ask, by signaling what to look for rather than providing a precise map of injuries.

The statement that the exact location of injuries can be determined by MOI isn’t accurate because MOI can suggest what injuries are more likely, but it cannot pinpoint exact sites. Patients with the same MOI can have different injury patterns, and some injuries arise from mechanisms that don’t neatly match a single location. So MOI is a clue to what to assess and how urgently, not a diagnostic map.

That’s why the most useful takeaway is that MOI may help you predict the potential severity of injuries, guiding you to prioritize evaluation and treatment, while remaining aware that it doesn’t determine precise injury locations. Also, a nonsignificant MOI does not rule out serious trauma, and a significant MOI does not guarantee death or permanent disability.
