Evoked potentials: nursing perspectives

An evoked potential is an electrical manifestation of the brain's response to an external stimulus. Evoked potential studies provide a sensitive, quantitative assessment of portions of the neurological system which may enhance clinical data but do not indicate specific diagnosis. Nurses, by enhancing self knowledge related to evoked potential studies, should be better able to present concise information to patient and families. The outcome will be a more knowledgeable and less anxious patient.
