2 Mechanism of Injury and Nature of Illness Free Online FlashCards

What does mechanism of injury (MOI) describe?

Mechanism of injury describes how an injury occurred and the forces involved.

What does nature of illness (NOI) identify?

Nature of illness is the patient’s primary medical problem or reason for seeking help.

When does scene assessment take place?

Scene assessment begins before patient contact and continues throughout the response.

What should responders do if a scene is unsafe?

Do not enter an unsafe scene. Stay at a safe distance, use appropriate PPE, and request qualified assistance when needed.

What can MOI suggest—and what can it not establish?

MOI can help predict injuries that are not obvious, but it does not prove an injury is present or rule one out.

Which event details help clarify MOI?

Consider the event’s height, speed, direction, impact points, restraint use, vehicle damage, ejection, and entrapment.

What clues can help identify a patient’s NOI?

Clues include the patient’s complaint, appearance, breathing, behavior, and medical history, along with witness reports and scene evidence.

How should responders use scene clues about illness?

Treat scene and witness clues as evidence, not conclusions; confirm information with the patient or reliable sources when possible.

Name several hazards responders should look for.

Examples include moving traffic, fire or smoke, electrical hazards, weapons, hazardous materials, unstable structures, blood, sharps, extreme temperatures, and animals.

How should responders manage identified hazards?

Keep a safe distance, use PPE appropriate to the risks, and follow local procedures. Withdraw or remain staged and request appropriate support if the scene is unsafe.

What patient-related risks should responders assess?

A patient may deteriorate, remain exposed to danger, or be harmed by unnecessary movement. Move them from danger only when it is safe and necessary.

Why should responders determine the number of patients?

Look beyond the first person found, especially after a collision or another incident that may involve multiple people.
