A nurse is assessing a 58-year-old client with amyotrophic lateral sclerosis (ALS). Which assessment finding would be most concerning and require immediate nursing intervention?
1Fasciculations observed in the upper extremities
2Dysphagia with frequent choking episodes during meals✓ 정답
3Muscle atrophy in the hands and forearms
4Hyperreflexia noted during neurological examination
해설
Dysphagia with frequent choking poses immediate aspiration risk, leading to pneumonia and respiratory compromise, requiring urgent intervention. Other findings like fasciculations, atrophy, and hyperreflexia are expected in ALS but less urgent.
Core Nursing ExplanationKey Concept Analysis: This question tests the nurse's ability to prioritize patient safety and identify the most life-threatening complication in a patient with Amyotrophic Lateral Sclerosis (ALS). ALS is a progressive neurodegenerative disease that affects upper and lower motor neurons, leading to muscle weakness, atrophy, and eventual paralysis. While all listed findings are characteristic of ALS, the nurse must use clinical judgment to determine which finding poses an immediate risk to the patient's airway, breathing, and circulation (ABCs).
Answer Rationale: Key Point! The correct answer is Dysphagia with frequent choking episodes during meals. This finding indicates impaired swallowing function, which directly threatens the patient's airway. Aspiration (the entry of food, fluids, or secretions into the lungs) is a critical and immediate complication. It can lead to aspiration pneumonia, respiratory distress, and potentially respiratory failure—a common cause of mortality in ALS. This requires urgent nursing interventions such as modifying diet consistency, implementing safe swallowing techniques, and possibly consulting a speech-language pathologist (SLP).
Distractor Analysis:
Watch out for confusion!Fasciculations observed in the upper extremities: While a classic early sign of ALS due to lower motor neuron involvement, fasciculations (muscle twitches) are not an immediate threat to life. They are an expected part of the disease progression.
Watch out for confusion!Muscle atrophy in the hands and forearms: Atrophy is also a hallmark of ALS, resulting from the denervation of muscles. Although it leads to disability, it develops gradually and does not constitute an acute emergency requiring immediate intervention.
Watch out for confusion!Hyperreflexia noted during neurological examination: This is a sign of upper motor neuron involvement (e.g., brisk reflexes). Like fasciculations and atrophy, it is a diagnostic and expected neurological finding in ALS but does not indicate an acute, life-threatening condition.
Related Concepts: Nursing care for ALS focuses on managing symptoms, preventing complications (especially respiratory and nutritional), and providing palliative support. Respiratory failure is the most common cause of death. Early signs of respiratory compromise include dyspnea on exertion, orthopnea, weak cough, and morning headaches from nocturnal hypoventilation. Monitoring forced vital capacity (FVC) is a key assessment.
Concept Summary ALS Pathophysiology: Degeneration of motor neurons in the brain and spinal cord.
Primary Threats: 1) Respiratory failure (from weak respiratory muscles), 2) Aspiration (from bulbar muscle weakness affecting swallowing/speech).
Nursing Priority: Always protect the airway first. ABCs take precedence over chronic, expected symptoms.
Key Interventions: Aspiration precautions, respiratory support, nutritional support (e.g., PEG tube), mobility aids, and psychosocial support.
Side-by-Side Comparison!
Assessment Finding in ALS
Clinical Significance
Priority Level
Dysphagia with Choking
Indicates bulbar involvement. High risk for aspiration and airway obstruction.
HIGH - Requires Immediate Action
Fasciculations & Atrophy
Signs of lower motor neuron damage. Expected, chronic progression.
LOW - Monitor, part of disease course.
Hyperreflexia & Spasticity
Signs of upper motor neuron damage. Expected, chronic progression.
LOW - Manage for comfort.
Shortness of Breath, Weak Cough
Signs of respiratory muscle weakness. Precedes respiratory failure.
HIGH - Requires Proactive Planning (e.g., BiPAP)
Anatomy, Physiology & Pharmacology Points Bulbar Muscles: These muscles, innervated by cranial nerves (especially IX, X, XII), control swallowing, speaking, and chewing. Their weakness in ALS leads to dysphagia, dysarthria, and risk of aspiration.
Drug Therapy: Riluzole is a disease-modifying agent that modestly prolongs survival by reducing glutamate-induced excitotoxicity. Edaravone is an antioxidant that may slow functional decline. These do not reverse symptoms but may slow progression.
Memory Tips ABCs for ALS: In ALS, think "Aspiration and Breathing are Critical." Any issue with swallowing (A) or breathing (B) jumps to the top of your priority list.
UMN vs. LMN Signs: Remember "Upper = Upgoing toes (Babinski), Uncontrolled movements (spasticity), Unusually brisk reflexes (hyperreflexia). Lower = Limp muscles (flaccidity), Loss of muscle (atrophy), Little twitches (fasciculations)."
High-Frequency NCLEX Topics
NCLEX frequently tests priority-setting and complication recognition in chronic neurological disorders. For ALS, the top two tested priorities are always: 1) Maintaining airway and preventing aspiration (from bulbar symptoms), and 2) Managing respiratory function (the ultimate cause of death). Expect questions that ask "Which finding requires immediate intervention?" or "Which client should the nurse see first?"
Watch Out for Question Variations! From Symptom to Intervention: "The nurse notes dysphagia in a client with ALS. Which action should the nurse take first?" (Correct answer: Initiate aspiration precautions—sit upright, thicken liquids, supervise meals).
From Assessment to Education: "A client with newly diagnosed ALS asks about the course of the disease. The nurse should explain that the most important focus of care will be on managing problems related to which area?" (Correct answer: Respiratory function).
Priority Amongst Multiple ALS Patients: "The nurse is caring for four clients with ALS. Which client requires the most immediate assessment? 1) Client with fasciculations, 2) Client reporting difficulty buttoning shirts, 3) Client coughing during breakfast, 4) Client with bilateral ankle clonus." (Correct answer: 3—coughing indicates active aspiration risk).Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 58, was admitted for dehydration and weight loss. He has a known history of ALS for 2 years. During lunch, you observe him attempting to drink thin apple juice. He suddenly begins coughing violently, his face turns red, and he appears panicked. His oxygen saturation on the monitor drops from 96% to 88%.
Nursing Intervention Strategy:
1. Immediate Action (Airway): Stop him from taking another sip. Encourage him to cough forcefully. If he cannot clear his airway, call for help and be prepared to perform suctioning. Position him upright or slightly forward. Administer oxygen as needed.
2. Assessment: After the acute episode, perform a focused assessment. Auscultate lung sounds for crackles (indicating aspiration). Re-assess swallowing: ask about the sensation of food "going down the wrong pipe." Complete a formal swallowing screen or request a bedside evaluation by a Speech-Language Pathologist (SLP).
3. Care Planning & Implementation:
Diet Modification: Collaborate with the SLP and dietitian. The diet will likely be changed to mechanical soft or pureed foods with nectar-thick or honey-thick liquids.
Meal Supervision: Ensure the patient eats in a high-Fowler's position, remains upright for at least 30 minutes after meals, and is never left alone while eating.
Alternative Nutrition: Discuss the possibility of a percutaneous endoscopic gastrostomy (PEG) tube for long-term nutritional support and medication administration, which can significantly reduce aspiration risk and improve quality of life.
Oral Care: Meticulous oral care before and after meals reduces the risk of aspirating oral bacteria.
Patient Safety and Precautions:
Key Point! Never give a patient with suspected dysphagia thin liquids or foods that are difficult to chew (like nuts or raw vegetables) without an SLP evaluation. Watch out for confusion! Do not assume a patient can swallow pills safely; some may need to be crushed (if not contraindicated) and given via PEG or changed to liquid formulations.
Nursing Procedure & Medication Flow Suctioning Procedure (for airway emergency):
1. Explain the procedure to the patient if possible.
2. Use appropriate suction pressure (100-150 mmHg for adults).
3. Pre-oxygenate with 100% oxygen if time allows.
4. Insert the Yankauer or catheter without applying suction.
5. Apply suction only while withdrawing the catheter, and limit each pass to 10-15 seconds.
6. Reassess airway patency and oxygenation.
Medication Administration via PEG Tube:
1. Verify the tube placement (check external length marking, pH of aspirate if possible).
2. Flush with 30 mL of water before and after administering each medication.
3. Administer medications separately; do not mix. Crush only medications that are safe to crush (not enteric-coated or extended-release).
4. Keep the head of the bed elevated at least 30 degrees during and for 30-60 minutes after administration.
A Word from Your Senior Nurse
"Nursing is not just about carrying out physician orders — it's about being the frontline guardian for your patients! In clinical practice, recognizing subtle changes in a patient's swallowing or a weak cough in someone with ALS can be the difference between preventing a hospital-acquired pneumonia and managing a life-threatening crisis. When studying for your boards, don't just memorize that 'dysphagia is a symptom of ALS' — connect it to the real, terrifying feeling of choking and the nurse's critical role in preventing it. That mindset will not only earn you a great score on the NCLEX but will make you a truly confident, professional nurse who sees the person behind the diagnosis."
