What immediate action should follow the assessment of an unconscious patient with a suspected diabetic emergency?

In the scenario of an unconscious patient with a suspected diabetic emergency, the immediate and critical action is to open and inspect the airway. This is essential because the patient’s level of consciousness is altered, which places them at risk for airway obstruction. Ensuring that the airway is clear allows for proper airflow and provides a safe pathway for potential interventions, such as administering glucose if indicated and the patient can protect their airway.

Following this step, rescue breaths may be necessary if the patient is not breathing adequately, so maintaining a patent airway is paramount. Other interventions, while important in their respective contexts, cannot be effectively executed without first ensuring that the airway is open and clear of obstructions.
