Final answer:
The next step in the assessment process after ensuring medical stability, including airway, breathing, and circulation, is to obtain a non-contrast CT head scan. This scan can help identify the type of stroke and determine if the patient is a candidate for thrombolytic therapy or other interventions.
Step-by-step explanation:
The next step in the assessment process after ensuring medical stability, including airway, breathing, and circulation, is to obtain a non-contrast CT head scan (c). This is important because a CT head scan can help identify the type of stroke and determine if the patient is a candidate for thrombolytic therapy or other interventions. It can also help rule out other conditions that may present with stroke-like symptoms.
