Problem: Mr. Lawson is to have several diagnostic tests to determine the cause of his neurologic symptoms, which include headache, visual disturbance, muscular weakness, and personality change.
1. How would you explain an electroencephalogram to Mr. Lawson? A computed tomography scan? Magnetic resonance imaging?
2. If you are to assess Mr. Lawson's "neuro signs" and he is using eyedrops for glaucoma that constrict the pupils, how would you evaluate his pupillary responses?
