A) The Captain has cataracts.
B) The Captain has a relative visual field loss on the left.
C) The Captain is exercising perceptual completion.
D) The Captain is experiencing confusion because of the stroke.

Question 7

Fred Farckle has a right hemianopsia.He reports that when he goes on community outings,he often bumps into people and other objects.This makes him anxious and uncomfortable,and he has stopped going out.Which of the following interventions would you use to address this limitation in mobility?
