MEDSURG | [Part 1] Neurological System Assessment

🧠 High-Yield Neurology Study Guide (RN Prep) 1️⃣ Neuron Basics & Injury Patterns Neurons: Excitable cells that transmit impulses via action potentials & neurotransmitters. Glial cells: Support neurons. 🧩 Astrocytes form scar tissue; Oligodendrocytes (CNS) + Schwann cells (PNS)make myelin. UMN Lesions: Weakness, spasticity, hyperreflexia, ↑ tone. (Think: stroke, SCI.) LMN Lesions: Flaccid paralysis, atrophy, fasciculations, ↓ reflexes. (Think: Guillain-Barré, spinal root injury.) 2️⃣ Neuro Protection & Fluid Meninges: Dura → Arachnoid → Pia. CSF: 150 mL circulates; cushions brain; made in choroid plexus. BBB: Blocks toxins; lipid-soluble drugs cross easiest. 3️⃣ Neuro Assessment Essentials Vitals: HR 60–100 bpm, RR 15–20, SpO₂ > 95%, BP 100–140/60–90. LOC: GCS = Eyes + Verbal + Motor. Pupils: PERRLA = equal, round, reactive, accommodate. Language: • Broca = expressive (can’t speak) 🗣️ • Wernicke = receptive (word salad). Speech Motor: Dysarthria; often w/ dysphagia. 4️⃣ Red-Flag Findings ⚠️ Nystagmus: Cerebellar/brainstem lesion or toxicity. Areflexia: LMN issue. Hyperreflexia/Clonus: UMN lesion. Analgesia/Anesthesia: Sensory tract damage. Astereognosis: Parietal cortex lesion. 5️⃣ Cranial Nerves 🧩 (key ones) I = Smell 👃 II = Vision 👁️ III, IV, VI = Eye movement/pupil V = Face sensation + chew VII = Expression/taste (ant 2/3) X = Gag, swallow, voice 6️⃣ Diagnostics & Nursing Pearls Lumbar Puncture: L3-L5; flat after, ↑ fluids 💧. ⚠️ Contra: ↑ICP, anticoag use.Post-LP HA: from ↓ CSF pressure. CSF: • Bacterial: ↑P, ↑WBC (poly), ↓glucose • Viral: ↑mono cells, nml glucose • SAH: RBCs + xanthochromia (yellow). CT: Fast for bleed/TBI; if contrast → hold Metformin 48 h. MRI: No metal! (pacers, implants, shrapnel). Angiography: NPO; monitor site/bleeding; leg flat 4-6 h. 7️⃣ Labs & Metabolic Links Na⁺↓ (SIADH/CHF) → confusion/seizure. Na⁺↑ (dehydration) → irritability. K⁺↓ (diuretics) → muscle weakness. K⁺↑ (renal fail, ACEi) → arrhythmias. Vit B₁₂↓ → neuropathy + megaloblastic anemia. Thiamine (B₁)↓ → Wernicke’s encephalopathy (alcohol use). Ammonia ↑ → hepatic encephalopathy (liver fail).

MEDSURG | PART2 PRIMER Neuro Disorders

🧠 HIGH-YIELD NEURO NURSING STUDY GUIDE ⚡ This guide hits the 20% of neuro content that gives you 80% of your clinical edge—rapid, focused, and straight to what matters in exams and practice. 🩸 Trauma & ICP Mild TBI: GCS ≥13, minor capillary bleed. Mod/Severe TBI: GCS 9–12/≤8. Watch for Cushing’s Triad 🚨 (↑BP, ↓HR, irregular resp). ➤ Manage w/ mannitol or hypertonic saline, maintain airway, avoid hypoxia. Epidural Hematoma: ⚠️ Lucid interval, then coma. Ipsilateral dilated pupil → immediate surgery. Basilar Skull Fx: Raccoon eyes, Battle sign, CSF leak. Prevent infection w/ IV ABX. 🧬 Cerebrovascular Emergencies Ischemic Stroke: Sudden neuro deficit. “Time = Brain.” ➤ rtPA within 4.5 h 🕐, thrombectomy up to 24 h if eligible. ➤ Maintain BP ≤185/110 mmHg if thrombolytics planned. Hemorrhagic Stroke: Often hypertensive. High early mortality. Manage ICP, avoid anticoags. Dysphagia Precaution: Keep NPO until swallow eval—aspiration kills faster than stroke. 🦠 CNS Infections Bacterial Meningitis: Fever + nuchal rigidity + petechial rash 🚨 ➤ Draw cultures → start IV ABX + dexamethasone STAT. Viral Encephalitis (HSV): Hallucinations, confusion → IV Acyclovir immediately. ⚡ Seizures Tonic-Clonic: Protect airway, pad rails, do NOT restrain or put anything in mouth. ➤ Document onset, duration, postictal phase. Status Epilepticus: ≥5 min seizure → IV/IM Lorazepam or Midazolam STAT. Watch for aspiration, cardiac arrest, cerebral edema. Todd Paresis: Temporary weakness post-seizure (not stroke!). 💊 Anticonvulsants Phenytoin: Check levels, CBC, LFTs. Gingival hyperplasia → oral care. Carbamazepine: No grapefruit juice. Risk: dizziness, rash, bleeding. Valproic Acid: ⚠️ Liver toxicity, bleeding, pregnancy danger. 🧍‍♂️ Chronic Neuro Disorders Parkinson’s: ↓Dopamine. Tremor, rigidity, bradykinesia. ➤ Carbidopa/Levodopa = gold standard. Teach “on/off” periods. ➤ Avoid excess Vit B6 & tyramine (if on MAO-B inhibitors). Myasthenia Gravis: Weakness worse w/ exertion. ➤ Give anticholinesterase meds on time, monitor resp status. Multiple Sclerosis: Demyelinating autoimmune flare-ups. ➤ Avoid heat, infection, fatigue. Corticosteroids for exacerbations. 💣 Red-Flag Drugs & Contraindications Triptans: 🚫 in CAD, HTN, PVD. Antiseizure meds: Never stop abruptly → rebound SE. Anticholinesterase OD: Cholinergic crisis (drooling, bradycardia, weakness).
