What are the steps you should follow for any injury or environmental emergency?

The correct choice is focused on the emergency action steps that should be followed in any injury or environmental emergency. These steps typically include ensuring personal safety, checking the scene for any hazards, assessing the condition of the injured person, calling for emergency assistance if necessary, and providing appropriate care based on the situation.

Following emergency action steps is crucial because they provide a systematic approach to handling emergencies, helping to ensure the well-being of both the responder and the person in need. This structured strategy enables responders to adequately assess the situation and determine the severity of the injuries, thereby allowing them to prioritize care effectively.

In contrast, waiting for professional assistance does not address immediate needs and can result in further harm if critical first aid is not provided in a timely manner. Assessing and treating only minor injuries overlooks potentially more severe conditions that may require attention. Similarly, applying pressure to all wounds is not appropriate; while it's important to control bleeding with direct pressure if there is an active wound, not all injuries require this treatment technique, and some may even require specific interventions based on their nature.
