Study Notes
Neurology
- Decorticate positioning: Arms bent, legs straight, stiff; damage to the cortex.
- Decerebrate positioning: Arms and legs straight; severe damage to the cerebellum or brain stem.
-
Seizures:
- Tonic: Stiffness followed by loss of consciousness.
- Myoclonic: Quick muscle jerks.
- Clonic: Body spasms.
- Atonic: Sudden lack of muscle strength.
- Postictal phase: Occurs after a seizure, when patient returns to baseline.
- Status epilepticus: Seizures lasting more than 5 minutes or multiple seizures without regaining consciousness; convulsive (tonic-clonic) seizures are most dangerous.
-
Stroke:
- Risk factors: Hypertension, atherosclerosis, history of stroke, diabetes, smoking.
- Symptoms: Motor loss (hemiparesis or hemiplegia), communication loss (dysphasia, dysarthria, apraxia, aphasia), vision changes, decreased mental acuity.
- Start rehabilitation when patient is stable.
- Nursing interventions (NI): Control blood pressure, neurological assessment, position patient to decrease edema, bed rest, stool softeners.
- Ischemic stroke: Blockage of blood flow to the brain due to a clot.
- NI: Give tPA within 3-4 hours of symptoms.
- Hemorrhagic stroke: Brain bleed due to ruptured blood vessels.
- NI: Anticoagulation therapy is contraindicated.
-
Aneurysm: Bulge in a blood vessel that can lead to rupture (hemorrhagic stroke).
- Symptoms: Vision changes, headache, nuchal rigidity, dizziness.
- NI: Promote a calm environment, bed rest.
- Symptoms: Vision changes, headache, nuchal rigidity, dizziness.
-
Parkinson's Disease: Central nervous system disorder; low dopamine levels.
- Symptoms: Tremors, pill rolling movement, rigidity, stooped posture, bradykinesia, difficulties with gait.
- NI: Promote patient safety, schedule activities later in the day, calm environment, soft diet, physical therapy.
Increased Intracranial Pressure (ICP)
- Pressure builds in the skull; blocking brain circulation.
- Signs: Cushing's Triad (changes in level of consciousness or pupil size, headache, blurry vision, vomiting).
- NI: Elevate head of bed (HOB) 30 degrees, keep body midline, calm environment, stool softeners, avoid Val Salva maneuver.
Meningitis
- Inflammation of the membranes surrounding the brain and spinal cord.
- Caused by viruses, bacteria, or fungi.
- Symptoms: Photophobia (light sensitivity), drowsiness, confusion; nuchal rigidity (stiff neck), Brudzinski's and Kernig's signs; fever, headache, muscle pain.
- Diagnostic test: Cerebrospinal fluid (CSF) test.
- NI: Antibiotics, droplet/contact precautions, neurological assessment, vital signs, dark and calm environment, seizure precautions.
Guillain-Barré Syndrome
- Immune system attacks its own nerves, causing ascending paralysis.
- Symptoms: Paresthesia (numbness and tingling), difficulty breathing, pain, vision changes.
- NI: Assess respiratory status; mechanical ventilation may be needed.
Multiple Sclerosis
- Chronic disease affecting the brain and spinal cord, more common in women.
- Immune system attacks myelin sheath.
- Symptoms: Numbness, vision problems, slurred speech, fatigue.
- NI: Implement rest breaks; create voiding schedule; high-fiber diet, increased fluid intake.
Myasthenia Gravis
- Muscle weakness and fatigue of voluntary muscles.
- Symptoms: Diplopia (double vision), ptosis (drooping eyelids), weakness, and breathing issues.
- NI: Assess respiratory status, trach kit at bedside, cholinergic meds, cluster care.
Myasthenia Crisis
- Medical emergency due to worsening muscle weakness, causing respiratory failure.
- Caused by insufficient medication or stress.
- Symptoms: Worsening MG symptoms.
Cholinergic Crisis
- Excessive acetylcholine (ACh) in the neuromuscular junction.
- Caused by too much anticholinesterase medication.
- Symptoms: Cramps, diaphoresis (sweating), diarrhea.
- NI: Give antidote, atropine sulfate.
Amyotrophic Lateral Sclerosis (ALS)
- Progressive muscular disease; nerve cell degeneration.
- Affects voluntary muscle movements (walking, breathing, talking).
- NI: Assess respiratory status, encourage physical therapy/occupational therapy/speech therapy.
Autonomic Dysreflexia
- Medical emergency in spinal cord injury (T6 or higher).
- Symptoms: Severe hypertension, bradycardia, sweating, anxiety, headache.
- NI: Elevate HOB to 90 degrees, remove tight clothing, administer antihypertensive medications.
Basilar Skull Fracture
- Fracture of one of the bones at the base of the skull.
- Symptoms: Bruise behind the ear (battle sign), periorbital hematoma (raccoon eyes), halo sign, hearing loss.
- NI: Assess ABCs, neurological exam, GCS, CT scan.
Wernicke's Encephalopathy
- Disruption caused by low thiamine (Vitamin B1).
- Symptoms: Confusion, ataxia (loss of motor control), abnormal eye movements.
Spinal Cord Injuries
- Damage to the spinal cord.
- Different levels of injury result in varying degrees of deficits (e.g., paraplegia- TI to L4; quadriplegia/tetraplegia- C1 to C8; C2 to C3 - typically fatal).
- NI: Assess respiratory status, neuro checks; immobilize on a backboard; maintain body midline.
