A person who is receiving tests to confirm a diagnosis of Alzheimer's disease is preparing for a computerized tomography (CT) test. The patient becomes restless and is unable to follow the pre-examination directions given by the lab personnel.
 
  As the nurse who is assisting the patient, your best action at this time is:
  A) Tell the patient that refusing to cooperate will require having to return another day
  B) Give the patient the written instructions
  C) Take the patient to a quiet waiting area until it is time for the CT scan
  D) Make certain that the patient is tightly strapped to the examination table during the test
