Which of the following is NOT considered a cardinal sign of a minor acute injury?

In the context of minor acute injuries, the cardinal signs typically include intermittent pain, mild swelling, and skin redness. These signs indicate the presence of inflammation or irritation associated with the injury, which is common and expected in minor injury cases as the body responds to trauma.

Complete immobility, on the other hand, is not considered a cardinal sign of a minor acute injury. While there may be some restriction in movement associated with a minor injury, complete immobility suggests a more severe problem such as a fracture or a significant soft tissue damage. Minor injuries often allow for some degree of movement, albeit sometimes painful, distinguishing them from more severe injuries where complete rest or immobility may be required for healing. This context clarifies why the correct choice is one that identifies complete immobility as something outside the expected responses of minor acute injuries.
