Pathology  The pathology involving the CNS arises from injuries, vascular insufficiency, tumors, infections and disorders from other diseases. Neurological medical problems are due to interference with normal functioning of the affected cells Nervous System Anatomy and Physiology Review      The nervous system acts as a coordinated unit both structurally and functionally Communication network responsible for coordinating and organizing the functions of all body parts The body’s link to the environment Works with the endocrine system to maintain homeostasis Reacts in a split second Functions    1.Regulates system 2. Controls communication 3. Coordinates Activities of body system Divisions   Central nervous system ( CNS) : brain and spinal cord –interprets incoming sensory information and sends out instruction based on past experiences Peripheral nervous system ( PNS) : Cranial and spinal nerves extending out from brain and spinal cord---carry impulses to and from brain and spinal cord Neurological Terms        Anesthesia- complete loss of sensation Aphasia-loss of ability to use language Auditory/receptive aphasia- loss of ability to understand Expressive aphasia- loss of ability to use spoken or written word Ataxia- uncoordinated movements Coma- state of profound unconsciousness Convulsion- involuntary contractions and relaxation of muscles Neurological terms      Delirium- mental state characterized by restlessness and disorientation Diplopia- double vision Dyskeinesia- difficulty in voluntary movement Flaccidd- without tone- limp Neuralgia- intermittent, intense pain, along the course of a nerve Neurological terms      Neuritis- inflammation of a nerve or nerves Nystagmus- involuntary, rapid movements of the eyeball Paresthesia- abnormal sensation without obvious cause, with numbness and tingling Stupor- state of impaired consciousness with brief response only to vigorous and repeated stimulation Vertigo- dizziness Preparing a patient for a diagnostic test       Answer question that the patient may need clarification Diet orders –NPO??? Special room or equipment used Special medications required for test An informed patient will be more cooperative Nursing assessment     Baseline vital signs and neuro cks Know level education to develop an individualized teaching plan Determine awareness of actual or potential medical diagnosis Determine previous experence with Dx test Diagnostic test/ methods A. Computerized Tomography- CT or CAT scan computer analysis of tissues as x-rays pass through them; has replaced many of the usual tests: no special preparation or care after test CT scan  Nursing Interventions – – – – – – – Explain procedure – will be enclosed tunel Written consent Assess allergies to iodine Remove wigs hair pins or clips, partial denture plates Assess for pacemakers NPO 4 hours before if oral contrast is administered Encourage patient to drink fluids to avoid renal complications and to promote excretion of the dye Diagnostic test/ methods  B. lumbar puncture- spinal tap – – – – Done under local anesthesia a puncture is made at the junction of the third and fourth lumbar vertebrae to obtain a specimen of cerebrospinal fluid (CSF) CSF pressure measured Used to inject medications- spinal anesthesia Used to inject diagnostic materials –air or dyemyelogram Lumbar puncture  Nursing interventions – – – – – – – – – Written consent Monitor vital signs Have patient empty bowel and bladder Position the patient Label and number specimens Keep patient supine 4-8 hours Observe for headache and nuchal rigidity Observe for mobility of extremities, pain, ability to void Monitor site for leakage Diagnostic test/ methods  Cerebral Angiography- intraarterial injection of radiopaque dye to obtain an xray film of the cerebrovascular circulation Cerebral angiography  Nursing interventions – – – – – – – – – – Written consent Assess for allergy to iodine NPO past midnight Administer preprocedure medications Observe arterial puncture site Monitor extremity for adequate circulation- pain tenderness bleeding temperature and color Pedal pulses and vital signs q 1 hour Provide ice pack to puncture site Bedrest 12- 24 hours Force fluids- to increase excretion of dye Diagnostic test/ methods  Electroencephalography (EEG)- electrodes are placed on unshaven scalp with tiny needles and electrode jelly EEG  Nursing Inventions – – – – – – – – – – Anticipate patient’s fears about electrocutions Explain procedure Written consent Hair should be clean Do not give stimulants/ depressants before test /consult with M.D. about meds Administer sedatives or hypnotics if ordered No smoking or caffeinated beverages before the test Eat full meal before the test –hypoglycemia may alter brain waves Stress need for restful sleep before the test sleep deprivation may cause abnormal brain waves Wash hair and scalp after test Diagnostic test/ methods  Brain Scan-after injection of a radioisotope, abnormal brain tissue will absorb more rapidly than normal tissue: this can be detected with a Geiger counter to diagnose brain tumors Brain Scan  Nursing interventions – – – – – NPO 4 hours before test Remove wigs, hair clips or pins, Assess for iodine allergies If ordered give sedation Encourage fluids after test to increase excretion of dye Diagnostic test/ methods  Magnetic Resonance Imaging- ( MRI) uses combination of radio waves and a strong magnetic field to view soft tissue ( does Not use x-rays or dyes) ; produces a computerized picture that depicts soft tissues in high – contrast color MRI  Nursing interventions – – – – Written consent Explain procedure- will have to remain perfectly still in the narrow cylinder-shaped machine .
