Comprehensive and Detailed Explanation:

The correct answer is A because the posterior cerebral artery (PCA) supplies the occipital lobes and the inferior temporal lobes. Ischemia within this territory characteristically produces visual field defects such as contralateral homonymous hemianopsia, visual processing deficits like visual agnosia, and damage to the fusiform gyrus resulting in prosopagnosia (the inability to recognize familiar faces). Option B is incorrect because anterior cerebral artery strokes cause lower extremity motor and sensory impairment along with abulia. Option C is incorrect because middle cerebral artery strokes result in contralateral face and arm weakness, sensory loss, and aphasia or neglect. Option D is incorrect because the anterior choroidal artery supplies deep structures such as the posterior limb of the internal capsule and optictract. SCRN nurses master cerebral vascular anatomy to correlate specialized visual and cognitive deficits with regional brain lesions.
