What is the first step in the assessment of a conscious adult patient?

The first step in the assessment of a conscious adult patient is to check for responsiveness and airway. This step is critical because it enables the responder to determine the patient's level of consciousness and ensure that the airway is clear. If a patient is conscious and responsive, it indicates that they are capable of maintaining their airway. Ensuring that the airway is patent is essential in preventing potential complications, such as airway obstruction, which can lead to inadequate ventilation and oxygenation.

Beginning with responsiveness also allows the clinician to gauge the patient's awareness and orientation, providing vital information about their neurological status. Once this initial assessment is complete, other steps can be taken, like administering oxygen if needed or performing a more detailed head-to-toe assessment for signs of injury or illness.
