Amyotrophic Lateral Sclerosis — NCLEX Cheat Sheet
Motor neuron death, mind intactAlso known as: ALS · Lou Gehrig's disease · motor neuron disease
Use this quick-reference guide to spot, treat, and prevent Amyotrophic Lateral Sclerosis on the NCLEX. Keep it handy during review and on exam day!
🩺📒 The 1-minute cheat sheet
📌 Mechanism
- Upper + lower motor neuron loss
- Progressive, fatal, no cure
- Cognition/senses stay intact
🩺 Signs
- Progressive muscle weakness/atrophy
- Fasciculations, spasticity, cramps
- Dysphagia, dysarthria late
✅ Do
- Riluzole slows progression
- Aspiration precautions, PEG tube
- Communication aids, support
🚩 Report
- Resp failure = #1 death cause
- Discuss advance directives early
📚 Amyotrophic Lateral Sclerosis — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Key points
Understand these first- Progressive muscle weakness, atrophy, fasciculations (twitching), and spasticity occur as motor neurons die.
- Mental status, intelligence, and sensation remain intact, while voluntary muscle control is lost.
- Dysphagia and dysarthria develop as bulbar muscles weaken, increasing aspiration risk.
- Respiratory muscle weakness progresses to respiratory failure, the usual cause of death.
- The disease is relentlessly progressive with no cure; riluzole may modestly slow progression.
Nursing priorities
What to do, in order- Monitor respiratory function closely and support ventilation as the disease advances.
- Assess swallowing and implement aspiration precautions; anticipate enteral feeding as dysphagia worsens.
- Provide a communication method (boards, devices) as speech declines, since cognition stays intact.
- Prevent complications of immobility with repositioning, skin care, and range-of-motion exercises.
- Discuss and document advance directives and end-of-life wishes while the patient can communicate.
Red flags — report now
Escalate immediately- Increasing respiratory distress or declining vital capacity signals respiratory failure, the leading cause of death.
- Choking, coughing, or inability to manage secretions indicates high aspiration risk, hold oral intake.
- Aspiration pneumonia from dysphagia is a frequent and dangerous complication.
Patient teaching
What patients must know- The mind stays sharp even as the body weakens, so maintaining communication tools is important.
- Plan early for advance directives, ventilation decisions, and feeding-tube preferences.
- Use assistive and communication devices, energy conservation, and support services to maintain quality of life.
❓ Amyotrophic Lateral Sclerosis: NCLEX FAQs
What are the priority nursing interventions for Amyotrophic Lateral Sclerosis?
Monitor respiratory function closely and support ventilation as the disease advances. Assess swallowing and implement aspiration precautions; anticipate enteral feeding as dysphagia worsens. Provide a communication method (boards, devices) as speech declines, since cognition stays intact. Prevent complications of immobility with repositioning, skin care, and range-of-motion exercises.
What are the warning signs of Amyotrophic Lateral Sclerosis a nurse must report?
Increasing respiratory distress or declining vital capacity signals respiratory failure, the leading cause of death. Choking, coughing, or inability to manage secretions indicates high aspiration risk, hold oral intake. Aspiration pneumonia from dysphagia is a frequent and dangerous complication.
What do I need to know about Amyotrophic Lateral Sclerosis for the NCLEX?
