    • Oral analgesics for headache
    • Observe sterile dressing at insertion site for bleeding or drainage
  7. electroencephalogram (EEG): purpose
    Records electrical activity of brain
  8. electroencephalogram (EEG): preparation and testing
    • Explain procedure
    • Procedure done by technician in a quiet room
    • Painless
    • Tranquilizer and stimulant medications withheld for 24–48 hours pre-EEG

    • Observe for seizure activity in seizure-prone clients
  10. encephalography: purpose
    Evaluates brain structure through sound waves
  11. encephalography: preparation and testing
    Explain procedure—hand-held transducer used to record sound waves
  12. encephalography: post-test nursing care
  13. computed tomography (CT): purpose
    Detects hemorrhage, infarction, abscesses, tumors

    • Informed consent
    • Explain procedure
    • Painless
    • Immobile during exam
    • If contrast dye used, may experience flushed, warm face, and metallic taste during injection
  15. computed tomography (CT): post-test nursing care
    • Assess for allergic responses to contrast dye (e.g., rash, pruritus, urticaria)
    • Encourage PO fluids
  16. mylogram: purpose
    Visualizes spinal column and subarachnoid space
  17. mylogram: preparation and testing
    • Informed consent

    • Table will be moved to various positions during test
  18. mylogram: post-test nursing care
    • Neurologic assessment every 2–4 hours
    • When metrizamide water-soluble dye used, head should be raised 30-45° for 3 hours
    • Oral analgesics for headache
    • Encourage PO fluids
    • Assess for distended bladder
    • Inspect injection site
    • Assess for allergic responses to contrast dye (e.g., rash, pruritus, urticaria)
  19. positron emission tomography (PET scan): purpose
    Used to assess metabolic and physiological function of brain; diagnose stroke, brain tumor, epilepsy, Parkinson’s disease, head injury
  20. positron emission tomography (PET scan): preparation and testing
    • Client inhales or is injected with radioactive substance, then is scanned
    • Tell client may experience dizziness,headache
    • Teach relaxation exercises
