What are the components of a thorough basic life support (BLS) assessment?

The components of a thorough basic life support (BLS) assessment consist primarily of evaluating the airway, breathing, and circulation. These three elements are critical because they represent the immediate life-sustaining functions that must be addressed in emergency situations.

First, ensuring that the airway is clear is essential, as any obstruction can lead to suffocation. The next step involves assessing breathing; the responder needs to determine if the person is breathing adequately or at all. Lastly, circulation must be evaluated to check for a pulse and blood flow, which are vital for sustaining life.

The additional component of "disability evaluation" helps assess the neurological status of the individual, checking for responsiveness or signs of stroke. This comprehensive assessment ensures that all life-saving interventions can be effectively implemented.

The other options may contain relevant medical assessments or evaluations, but they do not specifically capture the core focus areas of BLS, which are foundational for providing immediate care in emergencies.
