The nurse is discouraged because the patient exhibiting negative symptoms of schizo-phrenia has shown no improvement with the planned interventions to reduce the symp-toms. The mentor's remark that helps place the problem in perspective is:
 
  a. You aren't responsible for the behavior of any other person.
  b. Patients can be perverse and cling to symptoms despite our efforts.
  c. Negative symptoms have been associated with genetic pathology.
  d. It will take several trail and error' attempts to get the right combination care.

Question 2

The nurse is preparing a patient for a positron emission tomography (PET) scan. Which instructions will the nurse include? Select all that apply.
 
  a. There will likely be a 30 to 45 minute wait between the injection and the begin-ning of the scan.
  b. A blindfold and earplugs may be used to help decrease reaction to the environ-ment during the scan.
  c. Make every attempt to lie still during the scan because movement will affect the imaging produced.
  d. No food or fluids are to be ingested for at least 8 full hours before the scan and none during the scan.
  e. Staying awake during the scan is important since the results are altered when the patient is in any phase of the sleep state.

Answer to Question 1

ANS: C
A complex disorder, such as schizophrenia, most likely has multiple contributing factors, in-cluding genetic predisposition, prenatal development, and the environment. Nurse frustration can be alleviated by helping the nurse realize that negative symptoms may be the result of actual brain dysfunction, rather than psychologically determined behaviors; thus the remain-ing options are not appropriate since they do not address the complexity of the problem.

Answer to Question 2

ANS: A, B, C, E
Appropriate patient preparation for a PET scan would include information regarding the time interval between injection of the isotope and the actual scan, the fact that steps will be taken to minimize the effects of sights and sounds during the scan, lying still is critical to achieving a quality image, and that being asleep during the scan will alter the results. It is not necessary to fast before or during the scan.
