During an initial assessment, what should be determined if an adult patient is found unresponsive?

Determining whether an adult patient is unresponsive requires a systematic approach to ensure the safety and well-being of the patient. The correct choice emphasizes checking both breathing and pulse immediately after establishing that the patient is unresponsive. This step is crucial because it allows the responder to assess the patient's circulation and respiration status.

If the patient is found to be breathing and has a pulse, further immediate interventions may not be needed beyond monitoring the patient until emergency services arrive. Conversely, if the patient is not breathing or lacks a pulse, immediate CPR is essential to maintaining circulation and oxygenation, thereby preventing irreversible damage.

The other options do not adequately address the necessary steps following the confirmation of unresponsiveness. Focusing solely on the airway would neglect critical assessments of breathing and circulation, which are vital for determining the need for CPR. Starting immediate CPR without assessing the pulse and breathing could lead to inappropriate and unnecessary resuscitation efforts in cases where they are not required. Lastly, looking for a medical ID is useful but should only occur after assessing basic life functions, which is the priority in an emergency situation.
