A client with depression tells a nurse that he is to have a test that involves the recording of an electroencephalogra m (EEG) throughout the night. The nurse most likely identifies this testing as which of the following?
 
  A) Sleep deprivation EEG
  B) Polysomnography
  C) Evoked potentials
  D) Functional magnetic resonance imaging

Question 2

A client is scheduled for a challenge test. Which of the following would a nurse include when explaining this test to the client?
 
  A) Intravenous administration of a substance to induce symptoms
  B) Application of electrodes to the scalp for monitoring
  C) Evaluation of electrical impulses recorded on graph paper
  D) Exposure to a flashing strobe light to elicit abnormal activity

Answer to Question 1

Ans: B
Polysomnography is a special procedure that involves recording an EEG throughout a night of sleep. A sleep deprivation EEG involves keeping a client awake the night before the EEG evaluation. Evoked potentials measure changes in electrical activity of the brain as a response to a given stimulus. Functional magnetic resonance imaging creates images of changes in blood flow.

Answer to Question 2

Ans: A
A challenge test is usually conducted by intravenously administering a chemical known to produce a specific set of psychiatric symptoms. The application of electrodes for monitoring and the evaluation of electrical impulses recorded on graph paper are involved with electroencephalogra phy (EEG). Using a flashing strobe light may be used to gather additional information when EEG is done.
