What should a patient be told to expect during an EEG?

It will be painful
It will last only a few minutes
They must remain still and may need to hyperventilate
Results will be immediate

The correct answer is: They must remain still and may need to hyperventilate

During an EEG (electroencephalogram), the patient should be informed that remaining still is crucial for obtaining accurate results. Movement can create artifacts that interfere with the recording of brain activity. Patients may also be asked to hyperventilate, which can help to provoke changes in brain activity that are important for diagnosis, particularly in the context of conditions such as epilepsy. This preparation is essential because the EEG is designed to capture electrical activity in the brain, and the quality of the data is highly dependent on minimizing external interference. Understanding this allows the patient to adequately prepare and cooperate with the procedure, ensuring that the results reflect their true neurological state. While the procedure is generally non-invasive and painless, and it can last longer than just a few minutes, communicating the requirements for stillness and the possibility of hyperventilation is vital for the success of the test.
