Challenge Your Exam Readiness With Our Free SCRN Practice Questions

Comprehensive and Detailed Explanation:

The correct answer is A because the patient is presenting well within the standard 4.5-hour therapeutic window for intravenous alteplase, has no evidence of intracranial hemorrhage on CT, and has blood pressure readings well below the exclusion threshold of 185/110 mmHg. Given the focal neurological deficits suggesting a large vessel occlusion (hemiparesis and neglect), immediate administration of intravenous thrombolysis combined with concurrent evaluation for mechanical endovascular thrombectomy represents the gold standard of hyperacute care. Option B is incorrect because a "wait and watch" approach wastes critical penumbral tissue and violates the principle that "time is brain." Option C is incorrect because aggressively lowering blood pressure below normal parameters before reperfusion can precipitate hypoperfusion and enlarge the ischemic core. Option D is incorrect because waiting for advanced perfusion imaging when non-contrast CT is already negative and the patient is within the window creates dangerous treatment delays.
