Answer to Question 1

ANS: C
Clinical observations of generalized seizures indicate that the initial involvement is from both hemispheres. Focal seizures may arise from any area of the cerebral cortex, but the frontal, temporal, and parietal lobes are most commonly affected. Partial seizures are caused by abnormal electrical discharges from epileptogenic foci limited to a circumscribed region of the cerebral cortex. A seizure disorder that is acquired is a result of a brain injury from a variety of factors; it does not specify the type of seizure.

Answer to Question 2

ANS: D
Although the etiology of Reye's syndrome is obscure, most cases follow a common viral illness, either varicella or influenza. A potential association exists between aspirin therapy and the development of Reye's syndrome; thus use of aspirin is avoided. No immunization currently exists for Reye's syndrome. Reye's syndrome is not correlated with head injuries or bacterial meningitis.
