If an adult patient is unresponsive, breathing, and has a pulse, what should be the first action taken?

When an adult patient is unresponsive but still breathing and has a pulse, the priority is to ensure that the airway is open and clear while also addressing any immediate needs related to their condition. Performing a primary assessment and initial interventions involves checking the airway, breathing, and circulation, which are fundamental elements of basic life support.

In this scenario, ensuring that the patient's airway is not obstructed takes precedence, as even a patient who appears to be breathing may have a compromised airway. Initial interventions may include positioning the patient appropriately—usually in the recovery position—to maintain an open airway and allow for proper breathing.

This response is crucial because the primary assessment helps to identify any life-threatening conditions that need immediate attention, while initial interventions aim to stabilize the patient until further help is provided. Waiting to reassess or activate emergency services without first ensuring basic life support measures could lead to a rapid deterioration of the patient's condition.
