A nurse is caring for a client with amyotrophic lateral sclerosis (ALS) who is experiencing progressive muscle weakness and difficulty swallowing. Which nursing intervention should be the highest priority?

## 보기

1. Encourage the client to maintain independence in all activities of daily living
2. Implement aspiration precautions and modify diet consistency **✔ 정답**
3. Provide emotional support and counseling for depression
4. Schedule physical therapy sessions to strengthen weakened muscles

**정답: 2**

## 해설

Aspiration precautions and diet modification are the highest priority for ALS clients with dysphagia to prevent life-threatening aspiration pneumonia. Other interventions are important but do not address the immediate safety threat.

Understanding the Priority: Airway and Safety First

For a client with amyotrophic lateral sclerosis (ALS) experiencing progressive muscle weakness and dysphagia, the highest priority nursing intervention is to implement aspiration precautions and modify diet consistency. This decision is rooted in the fundamental nursing principle of the ABCs (Airway, Breathing, Circulation). Progressive bulbar involvement in ALS leads to dysfunction of the swallowing mechanism, directly threatening airway patency.

Pathophysiology of Dysphagia in ALS

The dysphagia in ALS is a form of neurogenic dysphagia (ND) resulting from the degeneration of both upper and lower motor neurons that control the swallowing muscles. The central pattern generator (CPG) for swallowing, located in the medulla oblongata, can be disrupted by the disease process, leading to a loss of coordinated swallowing [1]. This incoordination impairs the ability to protect the airway during the pharyngeal phase of swallowing, creating a high risk for aspiration—the entry of material below the level of the true vocal cords. The clinical consequence of this is not only immediate choking and respiratory distress but also the development of aspiration pneumonia, a leading cause of morbidity and mortality in this population. A study on neurogenic dysphagia confirms that complications like pneumonia requiring hospitalization are a critical outcome in patients with impaired swallowing [3].

Why Other Options Are Lower Priority

While all the listed interventions are relevant to the holistic care of a client with ALS, they do not address the most immediate threat to life. Using Maslow's hierarchy of needs, physiological safety takes precedence.

- Encouraging independence in ADLs is a crucial psychosocial and functional goal, but it becomes a secondary concern when the client cannot safely swallow their own secretions or food.

- Providing emotional support and counseling is essential for coping with the diagnosis, yet this psychosocial need is addressed after ensuring physical safety from aspiration.

- Scheduling physical therapy for strengthening is contraindicated for weakened muscles in ALS. The underlying pathology is neuronal degeneration, not disuse atrophy. Overexertion of these muscles can lead to fatigue and further functional decline, and it does not directly mitigate the risk of aspiration from an uncoordinated swallow.

Clinical Implementation of the Priority Intervention

The nurse’s immediate actions must focus on preventing aspiration. This begins with a clinical swallowing evaluation and implementing compensatory strategies. Modifying diet consistency based on a speech-language pathologist's (SLP) assessment is a cornerstone of management. This typically involves thickening liquids to a nectar or honey-like consistency to slow their transit, allowing the client more time to coordinate swallowing and airway closure . Aspiration precautions also include positioning the client upright at a 90-degree angle during meals, ensuring a distraction-free environment, and having suction equipment readily available. The goal is to maintain safe oral intake for as long as possible, as severe dysphagia significantly reduces quality of life and can lead to the need for discussions about alternative nutrition or, in extreme cases, interventions like aspiration prevention surgery .References (research sources)

## 임상 시나리오

ALS Dysphagia & Airway SafetyPrioritizing Aspiration Precautions
For ALS with neurogenic dysphagia, the highest priority is airway protection. The ABCs framework dictates that aspiration precautions supersede psychosocial or rehabilitative needs.

Immediately modify diet consistency to thickened liquids or pureed solids as tolerated. Position the client upright at 90 degrees during meals and keep them upright for 30 minutes post-feeding.

CautionDo not prioritize muscle-strengthening exercises; they are ineffective in ALS and can cause fatigue. Aspiration pneumonia is a leading cause of death, making strict adherence to diet modifications critical.

## 핵심 개념

- **Neurogenic Dysphagia** — Swallowing dysfunction caused by neurological disease affecting motor neurons controlling the swallowing mechanism, leading to incoordination and aspiration risk.
- **Aspiration** — Entry of food, fluid, or secretions below the level of the true vocal cords into the airway, which can cause pneumonia.
- **Bulbar Involvement** — Degeneration of motor neurons in the brainstem (medulla) affecting speech, swallowing, and tongue movement, common in ALS progression.
- **ABCs (Airway, Breathing, Circulation)** — A fundamental nursing framework for prioritizing care, placing airway patency and breathing as the highest immediate physiological needs.
- **Aspiration Pneumonia** — A lung infection caused by inhaling foreign material, a leading cause of morbidity and mortality in patients with dysphagia.
