Which of the following is the initial step in the primary assessment of a patient?

The initial step in the primary assessment of a patient is to check the airway. This is crucial because a patient’s airway must be clear for them to breathe; otherwise, they cannot receive the oxygen they need. If the airway is obstructed, the provider must address this immediately to ensure the patient can breathe adequately.

In wilderness and remote first aid, where resources may be limited, ensuring a clear airway can significantly impact the patient's outcome. Once the airway is confirmed to be open and clear, the first aider can then check for breathing and circulation. Establishing circulation, performing a disability check, and conducting an exposure assessment follow after addressing the airway. All these components are essential, but protecting and ensuring an open airway is the priority during the initial assessment.
