A nurse is teaching the parents of a child who has a new onset of seizures and is to undergo an electroencephalogram (EEG) about the procedure. Which of the following instructions should the nurse include in teaching?

A. "Ensure the child's hair is clean and without conditioner before the procedure.": This is important because any oils or products in the hair can interfere with the electrodes' ability to detect brain activity accurately. Clean, product-free hair helps ensure the best results from the EEG. B. "Give the child acetaminophen for pain following the procedure.": EEGs are generally non-invasive and do not typically cause pain, so administering pain relief afterward is usually unnecessary unless specified by a healthcare provider. C. "Make the child NPO before the procedure.": Typically, there is no need for the child to be NPO (nothing by mouth) for an EEG unless it is specified for a particular type of EEG that might involve sedation. Most routine EEGs do not require this. D. "Keep the child out of the sun for 4 hr following the procedure.": There are no standard recommendations related to sun exposure after an EEG. Therefore, this instruction is not applicable.
