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. Based on this assessment data, what part of the brain was injured? A) There was damage to localized areas of the prefrontal cortex in the right cerebral hemisphere. 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.

C) If the stroke is in the left hemisphere, the right side of the body will be paralyzed.

A patient reports that she has become completely deaf—she can't hear anything. Thorough tests on her ears indicate that her ears have not been damaged. Additional tests reveal that her deafness has been caused by damage to her ______. A) primary somatosensory cortex B) auditory association area C) somatosensory association cortex D) None of the listed responses is correct

D

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

D

An individual accidentally transected (cut across) the spinal cord between T1 and L1. This would result in ________. A) hemiplegia B) quadriplegia C) spinal shock only D) paraplegia

D

The blood-brain barrier is effective against ________. A) nutrients such as glucose B) alcohol C) anesthetics D) metabolic waste such as urea

D

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.

D As a triage nurse, you would class a patient whose main complaint is nausea and disorientation as class 2 because the confusion may indicate some kind of brain injury. He would be seen after the people who are obviously at risk of dying have been dealt with
