A nurse is reinforcing teaching with an adolescent who has a prescription for an electroencephalogram (EEG).Which of the following instructions should the nurse include in the teaching?

Choice A reason: Fasting is not typically required for an EEG, so this instruction is not necessary. Choice B reason: Washing the hair is important before an EEG, as it helps to remove any oils or substances that might interfere with the electrodes' ability to record brain activity. Choice C reason: A mild sedative is not a standard part of an EEG procedure. Choice D reason: Having a full bladder is not necessary for an EEG.
