    “Neurotransmitters are substances we consume that influence memory and mood.”
    Neurotransmitters protect us from harmful effects of free radicals.”
    How do you feel about having imbalanced neurotransmitters?”
  • Q2
    The parent of an adolescent diagnosed with schizophrenia asks the nurse, “My child’s doctor ordered a PET. What kind of test is that?” Select the nurse’s best reply.
    “PET means positron-emission tomography. It is a special type of scan that shows blood flow and activity in the brain.”
    “A PET scan passes an electrical current through the brain and shows brain-wave activity. It can help diagnose seizures.”
    It’s a special x-ray that shows structures of the brain and whether there has ever been a brain injury.”
    This test uses a magnetic field and gamma waves to identify problem areas in the brain. Does your teenager have any metal implants?”
