What is the first step in a primary or initial assessment of a patient?

In the initial assessment of a patient, checking if the patient is responsive is crucial because it helps gauge their mental status and level of consciousness. This step provides essential information about the patient's overall condition and helps ascertain whether immediate medical attention is required. A responsive patient can follow commands, answer questions, and interact, indicating that their airway is likely clear, and they may not be in immediate life-threatening distress.

Understanding a patient's responsiveness can also influence subsequent assessment steps, guiding the rescuer in prioritizing interventions such as airway management, breathing support, or calling for additional help. Ultimately, assessing responsiveness forms the foundation for ongoing evaluation and treatment, which is why it is considered the first step in primary assessment.
