__________ is a failure to act, such as failing to splint a victim's arm prior to moving them, thus causing further injury.

Nonfeasance refers to the failure to act when there is a duty to do so, which can result in harm to another person. In the context of the example provided, not splinting a victim's arm before moving them can lead to additional injury. This is a clear illustration of nonfeasance because, despite having the ability and responsibility to perform a specific action that could prevent harm, the individual chose not to take that action.

This concept is particularly important in emergency services and medical situations, where timely intervention can significantly affect outcomes for victims. Understanding nonfeasance is crucial for firefighters and other emergency responders, as their decisions can directly impact the well-being of those they serve.
