After Joe has a stroke, his doctor asks Joe to touch his right pointer finger to his chin—but Joe is unable to move his right hand. However, when the doctor stimulates Joe's pointer finger with a painful stimulus, Joe's muscles quickly move his hand away from the stimulus. The doctor concludes that ______. A) the stroke caused damage to Joe's frontal eye field which interfered with his effort to touch his chin B) the stroke caused damage to Joe's right primary motor cortex C) the stroke caused damage to Joe's right premotor cortex D) based on the doctor's observations, none of the listed answers are correct conclusions

A patient is admitted to the rehabilitation unit five days after having a stroke. The nurse assesses his muscle strength and determines that he has right-sided weakness.

B) There was damage to localized areas of the primary motor cortex in the right cerebral hemisphere. C) There was damage to localized areas of the premotor cortex in the right cerebral hemisphere. D) There was damage to localized areas of the primary motor cortex in the left cerebral hemisphere. E) There was damage to localized areas of the premotor cortex in the left cerebral hemisphere.

You are working in the ER when a young man in his twenties comes in. He has a normal build and seems confused and disoriented. When you ask whether anyone is with him, he does not seem to know, but nobody else speaks up, so he seems to be there alone. He cannot say why he is there. He says he is not in any pain and his neck is not stiff. There is no alcohol on his breath, and he denies having taken anything. A) The young man's disorientation may indicate a brain problem, so he should be seen right away, before anybody else. B) Emergency room treatment is not appropriate for this patient. He should sleep it off and see his family doctor if he still feels bad in the morning. C) You should wait until the person who brought him there arrives and gives you more information. He or she is probably just parking the car. D) The young man's disorientation may indicate a brain problem, but he is not dying. So he should be seen soon, but anyone with a life-threatening situation will take precedence.
