Philippine NLE frequently tests what NOT to do during a seizure as much as what TO do. Stating 'do not insert anything into the mouth' directly and giving the correct reason almost always earns a full mark.

Model Answer

1. Turn the patient to the lateral (side-lying) position. Rationale: This prevents aspiration of secretions or vomitus, maintaining a patent airway — the highest-priority safety concern. 2. Do not restrain the patient or insert anything into the mouth. Rationale: Restraining causes musculoskeletal injury; inserting objects into the mouth risks dental fractures, soft tissue trauma, and airway obstruction.

For any IV drug question, the NLE expects: (1) compatible diluent, (2) safe rate/route, (3) monitoring parameters. Cover all three for full marks on a 3-mark pharmacology question.

Model Answer

1. Diluent: Administer IV phenytoin in normal saline (0.9% NaCl) ONLY. It must NOT be mixed with dextrose solutions because phenytoin precipitates in glucose-containing fluids, rendering the drug ineffective. 2. Rate: Infuse slowly at no faster than 50 mg per minute in adults to prevent severe hypotension and cardiac dysrhythmias. Continuous cardiac and blood pressure monitoring is required during infusion. 3. Therapeutic level: The therapeutic serum level is 10–20 mcg/mL. Levels above 20 mcg/mL indicate toxicity (nystagmus, ataxia, confusion); levels below 10 mcg/mL indicate subtherapeutic dosing.

Myasthenia Gravis — Crisis Differential

Difficulty

hard

Template Id

T5

Examiner Tip

The Tensilon test differential is a classic NLE trap question. Remember the logic: if you give more drug (Tensilon) and the patient improves, they needed MORE drug (myasthenic). If they worsen, they already had TOO MUCH drug (cholinergic).

Model Answer

Both crises present with severe muscle weakness and life-threatening respiratory failure, requiring immediate airway and ventilatory support. However, they differ in cause and management: Myasthenic crisis is caused by too little anticholinesterase medication (under-treatment), infection, stress, or surgery. The patient has pure weakness without cholinergic signs. The Tensilon (edrophonium) test shows improvement in strength. Treatment is increasing the dose of pyridostigmine. Cholinergic crisis is caused by too much anticholinesterase medication (overdose), leading to excess acetylcholine. The patient shows SLUDGE symptoms: Salivation, Lacrimation, Urination, Defecation, GI cramping, and Emesis, plus muscle fasciculations and miosis. The Tensilon test worsens strength. Treatment is withholding the drug and administering atropine as the antidote. Priority nursing action in both: secure the airway and prepare for mechanical ventilation.

Examiner Tip

The NLE loves to test 'resting' vs. 'intention' tremor as a differential. Parkinson's = resting tremor. Cerebellar disease = intention tremor. State this distinction explicitly if asked.

Model Answer

The classic triad of Parkinson's disease consists of: (1) Tremor — a resting 'pill-rolling' tremor that is present at rest and decreases with voluntary movement; (2) Rigidity — cogwheel rigidity, a ratchety resistance felt when passively moving the limbs; and (3) Bradykinesia — slowness of voluntary movement, including a shuffling, festinating gait and mask-like facies. The underlying pathophysiology is the progressive loss of dopamine-producing neurons in the substantia nigra, causing an imbalance between dopamine (decreased) and acetylcholine (relatively increased) in the basal ganglia.

In GBS questions, the examiner is testing whether you understand that ascending paralysis is the danger. Any answer that correctly links 'ascending' to 'respiratory muscles' to 'respiratory failure' will earn the rationale mark.

Model Answer

The single most important ongoing assessment is serial monitoring of respiratory function, specifically measurement of vital capacity (tidal volume and forced vital capacity). Rationale: GBS causes ascending symmetric paralysis that begins in the lower extremities and progressively moves upward. The life-threatening danger is that paralysis can reach the intercostal muscles and diaphragm, causing acute respiratory failure requiring mechanical ventilation. Vital capacity less than 800–1000 mL signals impending respiratory failure and the need for intubation. Early detection is critical because respiratory arrest can occur suddenly.

Multiple Sclerosis and ALS — Comparison

Difficulty

Examiner Tip

The examiner is specifically testing whether you know that ALS PRESERVES sensation and cognition — this is the most-tested differentiating fact about ALS in NLE questions.

Model Answer

Multiple Sclerosis (MS): Pathophysiology — autoimmune destruction of the myelin sheath of CNS neurons (demyelination), disrupting nerve signal conduction. Primarily affects CNS white matter. Presentation — relapsing-remitting course; fatigue (most common symptom), visual disturbances (optic neuritis, diplopia), weakness, spasticity, numbness/tingling, ataxia, and bladder dysfunction. Cognitive function and sensation are variably affected. Prognosis — variable but not immediately fatal; patients may live for decades with disability. Amyotrophic Lateral Sclerosis (ALS): Pathophysiology — progressive degeneration of both upper and lower motor neurons in the CNS and spinal cord. Presentation — progressive muscle weakness, atrophy, fasciculations, spasticity, dysphagia, and dysarthria. Critically, SENSATION, COGNITION, and EYE MOVEMENTS are preserved. Prognosis — fatal, usually within 2–5 years from diagnosis due to respiratory failure. Key difference: MS affects sensation/sensation pathways and has a relapsing-remitting course; ALS affects ONLY motor neurons and is relentlessly progressive with preserved sensation and cognition.

For a 5-mark long-answer question on an infectious neurologic condition, examiners expect: infection control + immediate treatment + symptom management + monitoring + complication prevention + at least one nursing diagnosis. Organize by numbered headings to make it easy to award marks.

Model Answer

Introduction: Bacterial meningitis is a life-threatening inflammation of the meninges caused by organisms such as Neisseria meningitidis and Streptococcus pneumoniae. Nursing management focuses on rapid treatment, infection control, symptom management, and complication prevention. I. Infection Control / Safety Precautions: Place the patient on DROPLET PRECAUTIONS immediately for meningococcal (N. meningitidis) and Haemophilus influenzae meningitis. Maintain precautions until 24 hours after effective antibiotic therapy has begun. Use surgical mask and gown when within 3 feet of the patient. Ensure close contacts receive prophylactic antibiotics as prescribed (e.g., rifampicin) and report to the local health authority per DOH protocols. II. Immediate Medical Management Support: Administer empiric IV antibiotics as prescribed WITHOUT DELAY — do not wait for culture results because every hour of delay worsens prognosis. Administer corticosteroids (dexamethasone) as prescribed before or with the first dose of antibiotics to reduce inflammation and neurologic complications. III. Comfort and Environmental Measures: Provide a quiet, dimly lit room to reduce photophobia and phonophobia. Maintain the patient in a comfortable position (head of bed elevated 30°) to reduce ICP while maintaining cerebral perfusion. Use analgesics as prescribed for severe headache. Minimize unnecessary stimulation and clustering nursing care activities. IV. Neurologic Monitoring: Perform frequent neurologic assessments (GCS, pupillary response, vital signs) to detect rising intracranial pressure (ICP). Warning signs: worsening headache, vomiting, altered LOC, Cushing's triad (bradycardia, hypertension, irregular respirations). Monitor for seizures — initiate seizure precautions. V. Fluid and Electrolyte Balance: Monitor intake and output carefully. Bacterial meningitis can cause SIADH (syndrome of inappropriate antidiuretic hormone), leading to hyponatremia. Restrict fluids as prescribed if SIADH is suspected. VI. Prevention of Complications: Turn and reposition every 2 hours to prevent pressure ulcers. Maintain DVT prophylaxis (compression stockings, early mobilization when safe). Assess for septic shock (meningococcemia) — monitor vital signs for hemodynamic instability, petechial or purpuric rash. Conclusion / Priority Nursing Diagnosis: The priority NANDA nursing diagnosis is Risk for Ineffective Cerebral Tissue Perfusion related to increased ICP secondary to meningeal inflammation. Safe, timely administration of antibiotics and vigilant neurologic monitoring are the cornerstones of care.

For Parkinson's long-answer questions, the protein-levodopa interaction is the most-tested and most often forgotten detail. Mention it under BOTH nutrition and medication management to maximize marks.

Model Answer

Introduction: Parkinson's disease is a progressive neurodegenerative disorder caused by loss of dopaminergic neurons in the substantia nigra, resulting in the classic triad of resting tremor, cogwheel rigidity, and bradykinesia, along with postural instability and a shuffling festinating gait. Nursing care targets three priority domains: mobility, nutrition, and safety. I. MOBILITY A. Nursing Diagnosis: Impaired Physical Mobility related to bradykinesia, rigidity, and postural instability. B. Interventions: Encourage regular exercise and physical therapy; use wide-based gait and deliberate arm swinging to improve balance. Instruct the patient to 'march' or step over imaginary lines to counteract festination. Collaborate with physical therapist for a tailored exercise program. Allow extra time for all activities; rushing increases fall risk. Use assistive devices (walker, raised toilet seat, grab bars). Administer levodopa-carbidopa on a consistent schedule; peak drug effect should coincide with planned physical activity. II. NUTRITION A. Nursing Diagnosis: Imbalanced Nutrition: Less Than Body Requirements related to dysphagia, tremor, and medication effects. B. Interventions: Provide small, frequent nutrient-dense meals. Position the patient upright (90°) during eating and for 30 minutes after to prevent aspiration. Offer soft or semi-solid foods; thicken liquids if the SLP recommends. Avoid high-protein meals at times of levodopa administration, as dietary protein competes with levodopa absorption in the intestine, reducing its effectiveness. Ensure adequate fiber and fluid intake to prevent constipation (common in Parkinson's). Monitor weight weekly. III. SAFETY A. Nursing Diagnosis: Risk for Falls related to postural instability, festinating gait, and orthostatic hypotension. B. Interventions: Perform a fall risk assessment on admission and with every status change. Clear the environment of throw rugs, clutter, and low furniture. Ensure adequate lighting in the room and hallway. Educate the patient to rise slowly from sitting to standing (orthostatic hypotension is a side effect of levodopa-carbidopa). Use bed alarm and non-skid footwear. Assess for orthostatic blood pressure changes before ambulation. IV. MEDICATION MANAGEMENT: Administer levodopa-carbidopa on a strict consistent schedule; never skip or abruptly stop doses. Explain the 'wearing-off' phenomenon (return of symptoms near the end of dose interval) and 'on-off' fluctuations to the patient. Monitor for dyskinesias (involuntary writhing movements) as a sign of excess dopamine. V. PSYCHOSOCIAL: Encourage independence while providing assistance. Address depression and anxiety (common comorbidities). Involve family caregivers in discharge education. Conclusion: The priority nursing diagnosis is Risk for Falls; safety and mobility promotion are central to quality-of-life outcomes in Parkinson's disease.

Examiner Tip

This is a classic NLE differential. The single most important differentiating word is ONSET: gradual (dementia) vs. acute/sudden (delirium). Always state this distinction first.

Model Answer

Dementia is a chronic, progressive, and largely irreversible decline in cognitive function (memory, judgment, personality) that develops gradually over months to years. It has no identifiable single acute cause and is not typically reversible (e.g., Alzheimer's disease). Delirium is an acute, sudden-onset disturbance of consciousness and cognition, characterized by fluctuating levels of awareness, inattention, and often an identifiable precipitating cause (infection, medication toxicity, metabolic imbalance). Delirium is often reversible when the underlying cause is treated. Key difference: Dementia = gradual onset, chronic, irreversible. Delirium = sudden onset, acute, fluctuating, often reversible.

For any discharge teaching question on antiseizure drugs, 'never stop abruptly' is always the first and highest-priority point. State it first, include the rationale (status epilepticus), and then proceed to drug-specific side effects.

Model Answer

1. NEVER abruptly stop phenytoin even if feeling well — abrupt discontinuation can trigger status epilepticus, a life-threatening emergency. Any changes in medication must be made gradually under physician supervision. 2. Oral hygiene: Phenytoin causes gingival hyperplasia (overgrowth of gum tissue). Teach the patient to brush teeth after every meal with a soft toothbrush, floss daily, and visit a dentist regularly. 3. Therapeutic drug level monitoring: Maintain serum phenytoin levels at 10–20 mcg/mL. Signs of toxicity (levels above 20 mcg/mL) include nystagmus, ataxia, slurred speech, and confusion — report these immediately. 4. Avoid alcohol — alcohol lowers the seizure threshold and interacts with phenytoin, reducing its effectiveness. 5. Wear a medical identification bracelet stating the diagnosis of epilepsy and current medication. 6. Follow local driving restrictions — in the Philippines, patients with active seizure disorders must be seizure-free for a physician-determined period before driving. 7. Take phenytoin at consistent times daily; if a dose is missed, take it as soon as remembered unless the next dose is near — do not double the dose.

Heat sensitivity (Uhthoff's phenomenon) is so specific to MS that naming it with the correct mechanism almost always earns the trigger mark outright. Memorize the Uhthoff name for NLE-level responses.

Model Answer

Pathophysiology: Multiple sclerosis (MS) is a chronic autoimmune disorder in which the immune system mistakenly attacks and destroys the myelin sheath surrounding neurons in the central nervous system. This demyelination disrupts the conduction of nerve impulses along affected pathways, producing variable neurologic deficits depending on the location of demyelinating plaques. The disease typically follows a relapsing-remitting course, with periods of worsening (relapses) and partial recovery (remissions). Two major triggers nurses should teach patients to avoid: 1. HEAT (Uhthoff's phenomenon) — elevated body temperature worsens nerve conduction in demyelinated axons; patients should avoid hot environments, hot baths, saunas, and fever. 2. INFECTION and STRESS — both trigger immune activation and can precipitate relapses; teach hand hygiene, vaccination, stress-reduction techniques, and adequate rest.
