6. A granddaughter is worried that her grandfather is “losing his hearing.” Lately, he has been staying away from social gatherings that he always enjoyed, saying everybody mumbles. He is defiant in maintaining that there is nothing wrong with his hearing. However, he does complain that his ears have been ringing a lot lately. A. What are common manifestations of hearing loss in the elderly? B. What type of evaluation would be appropriate for determining if this man has a hearing loss, and the extent of his hearing loss? C. What are some things the granddaughter might do so that her grandfather could hear her better when she is talking to him? 7. A 70-year-old man complains that he gets this terrible feeling “like the room is moving around” and becomes nauseated when he rolls over in bed or bends over suddenly. It usually goes away once he has been up for a while. He has been told that his symptoms are consistent with benign paroxysmal positional vertigo. A. What is the pathophysiology associated with this man’s vertigo? B. Why do the symptoms subside once he has been up for a while? C. What methods are available for treatment of the disorder?
