A patient is scheduled for an electroencephalography (EEG) to aid in the diagnosis of a seizure disorder. Appropriate patient teaching for this diagnostic test would include which of the following?
A) Sedation will be given prior to the test.
B) The patient will be NPO prior to the test.
C) The patient may be sleep deprived prior to the test.
D) Coffee can be consumed in the meal prior to the test.
Ans: C
Feedback: To increase the chances of recording seizure activity, it is sometimes recommended that the patient be deprived of sleep on the night before the EEG. Sedation is not advisable as it may lower the seizure threshold in patients with seizure disorder and alter brain activity in all patients. The meal is not omitted prior to the test because an altered blood glucose level can cause changes in the brain-wave patterns. Coffee, tea, chocolate, and cola drinks are prohibited in the meal before the test because of their stimulating effect.
