2. I think the correct answer is to minimize stimulation but providing a conducive environment. So the answer could be B, or decrease ambient noise.
3. I think the correct answer is TPA, since the patient seems to be having an ischemic stroke/transient ischemic attack (TIA)
4. This is a hard question. It seems that his lesion doesn't fit a specific pattern. He should have cross-deficit owing to the level of motor and sensory involved. But he doesn't. It looks like he has Brown-Sequard on a very high spinal level, which is not possible. So i think the patient has conversion disorder. Not sure though.
