Final answer:
Homonymous hemianopsia is indicated by a patient having to turn their head to see the entire visual field.
Step-by-step explanation:
Homonymous hemianopsia is a visual field defect that occurs due to damage to the optic pathway. It usually presents as a loss of one half of the visual field in each eye. In the case of a patient who had a CVA (cerebrovascular accident), the finding that indicates homonymous hemianopsia is A. Patient has to turn head to see entire visual field. This is because the patient needs to compensate for the loss of vision in one half of the visual field by turning their head to see the entire visual field.
