The treatment for all aquatic life injuries begins with:

The correct answer, which is focusing on primary assessment, is vital in emergency situations, especially when it comes to treating injuries inflicted by aquatic life. This step allows a rescuer to evaluate the casualty's overall condition and identify any immediate life-threatening injuries or complications that need urgent attention.

Performing a primary assessment involves checking the person's responsiveness, airway, breathing, and circulation. This systematic approach ensures that any critical factors are addressed right away, which is essential when dealing with potential trauma from aquatic life. Additionally, understanding the severity of the injury can guide further treatment procedures, including whether it is safe to remove spines or stingers or to soak the affected area, which might otherwise complicate the situation.

Following a primary assessment sets the foundation for effective response and care, ensuring that the victim receives appropriate treatment tailored to their condition. It is particularly important in aquatic environments where injuries can quickly escalate due to other environmental factors, making the initial assessment crucial for safety and recovery.
