YMCA Basic Life Support (BLS) Training Practice Test

When assessing an unresponsive adult who has a definite pulse and normal breathing, the most appropriate next step is to maintain an open airway. This is crucial because even though the individual has a pulse and is breathing normally, their level of consciousness indicates that they may not be able to keep their airway clear on their own. Maintaining an open airway ensures that breathing remains unobstructed, which is vital for oxygenation and preventing potential airway compromise.

Immediately using an AED or starting CPR is not warranted since the individual has a pulse and is breathing adequately. Initiating rescue breathing is also unnecessary at this stage because the person is breathing normally on their own. Ensuring that the airway remains open is the priority in this situation to monitor their condition and intervene if breathing or pulse status changes.

In summary, focusing on maintaining an open airway supports the individual's ability to breathe while you assess their condition further or wait for emergency help.
