A client who is scheduled to undergo a sleep-deprivation electroencephalogram (EEG) in the morning is experiencing moderate anxiety about the procedure. Based on an understanding of this test, which of the following would the nurse avoid?
A) Explaining in depth what to expect during the upcoming procedure
B) Administering a benzodiazepine medication prescribed for anxiety
C) Taking a thorough history of the client's use of prescribed and illicit drugs
D) Giving the client a noncaffeinated beverage of her choice
Ans: B
If a sleep-deprivation EEG is to be done, caffeine or other stimulants that might assist the client in staying awake should be withheld because they may change EEG patterns. In addition, many medications change the wave patterns on an EEG. For example, the benzodiazepine class of drugs increases the rapid and fast beta activity. Therefore benzodiazepines should be avoided. Noncaffeinated beverages would be allowed. Explaining about the procedure would help to alleviate the client's anxiety. A thorough history about prescribed drug use would be important because it may reveal medications that could change the EEG wave patterns.
