What should a nurse teach a parent regarding their child's EEG procedure?

Teaching parents about their child's EEG procedure is focused on ensuring that the child is prepared adequately for optimal results. Offering decaffeinated beverages on the morning of the procedure is significant because caffeine can affect brain activity and potentially alter the EEG results. By avoiding caffeine, the nurse helps ensure that the EEG reflects the child's baseline brain activity without the stimulating effects of caffeine.

In contrast, not washing the child's hair the night before is crucial because hair products can interfere with the electrodes' attachment, but it is not as directly related to dietary restrictions. Likewise, withholding all foods the morning of the procedure is not typically necessary, as most guidelines do not require complete fasting and may allow for light meals. As for administering an analgesic the night before, this could risk altering the EEG readings if the medication affects brain function or activity.

Therefore, the emphasis on offering decaffeinated beverages supports achieving accurate and reliable results during the procedure, making it the most pertinent teaching point for the parent.
