When preparing a client for an electroencephalogram (EEG), what information should the nurse convey to the client?

When preparing a client for an electroencephalogram (EEG), conveying that the client will begin the procedure by lying still with their eyes closed is correct because this is critical for obtaining accurate results. During an EEG, the brain's electrical activity is monitored, and movement can introduce artifacts that may interfere with the readings. By lying still, especially with eyes closed, the client helps ensure that the data captured reflects the brain's activity without extraneous influences.

Other aspects of the EEG experience include that it typically does not require fasting, as fasting is not a standard requirement for this test. Mild discomfort is usually not associated with the test, as electrodes are placed on the scalp without needles or invasive procedures. The client is generally expected to remain awake and may be asked to participate in specific tasks, such as opening or closing their eyes, but they are not expected to be active in a way that involves movement during the recording phase, emphasizing the importance of stillness.
