A nursing instructor asks a student to explain the influence of chronobiology on depression. Which of the following would the student include when responding?
 
  A) The exact location of genes leads to identifying the gene responsible for causing depression.
  B) A break in the corpus callosum blocks information exchange between the right and left hemispheres.
  C) Damage to the posterior areas of the parietal lobe leads to altered discriminative sensory function.
  D) Internal and external triggers can elicit biologic rhythm changes indicative of clinical depression.

Question 2

A client who is scheduled to undergo a sleep-deprivation electroencephalogra m (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

Answer to Question 1

Ans: D
Chronobiology involves the study and measure of time structures or biologic rhythms. Zeitgebers are specific events that function as time givers or synchronizers and that set biologic rhythms. Some theorists think that psychiatric disorders may result from one or more biologic rhythm dysfunctions. For example, depression may be, in part, a phase advance disorder, including early morning awakening and a decreased time of onset of REM sleep.

Answer to Question 2

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.
