## 문제

A 3-year-old child is brought to the emergency department after ingesting an unknown amount of liquid household bleach 30 minutes ago. The child is alert and crying, with no visible burns around the mouth. What is the most appropriate initial nursing intervention?

## 보기

1. Induce vomiting immediately to remove the bleach from the stomach
2. Give small sips of water or milk to dilute the bleach and protect the esophagus **✔ 정답**
3. Administer activated charcoal to absorb the remaining bleach
4. Insert a nasogastric tube for immediate gastric lavage

**정답: 2**

## 해설

For caustic ingestion like bleach, dilution with small sips of water or milk is the priority to minimize tissue damage. Inducing vomiting, activated charcoal, and gastric lavage are contraindicated as they can worsen injury.

Understanding the Scenario

This question presents a classic NCLEX-RN priority-setting scenario involving a pediatric poisoning. A 3-year-old child has ingested an unknown amount of liquid household bleach, a corrosive alkali substance. The critical initial assessment findings are that the child is alert, crying, and has no visible burns around the mouth. Your task is to identify the most appropriate initial nursing intervention from the options provided.

Pathophysiology and Mechanism of Injury

Household bleach typically contains sodium hypochlorite, a caustic alkali. Alkaline substances cause injury through a process called liquefactive necrosis. This chemical reaction saponifies fats and dissolves proteins in the tissues, leading to deep, rapid penetration and severe tissue damage [1]. The severity of the esophageal and gastric injury depends on the substance's concentration, volume, and the duration of contact with the mucosa. Even without visible oral burns, significant esophageal damage can occur, a fact highlighted in case reports of accidental ingestions [1].

Analyzing the Intervention Options

Let's evaluate each option based on the principles of toxicology and the nature of the ingested substance.

*   Option 1: Induce vomiting immediately. This is contraindicated. Re-exposing the already damaged esophageal mucosa to the caustic agent through vomiting causes re-injury and increases the risk of aspiration and perforation. This principle is a cornerstone of caustic ingestion management.

*   Option 2: Give small sips of water or milk to dilute the bleach and protect the esophagus. This is the correct initial action. The goal is to dilute the caustic agent remaining in the esophagus and stomach, thereby reducing its concentration and the duration of contact with the mucosa. A small volume of a neutral diluent like water or milk is recommended to minimize the risk of emesis and further tissue damage.

*   Option 3: Administer activated charcoal. This is ineffective and contraindicated. Activated charcoal does not bind to caustic alkalis like sodium hypochlorite. Furthermore, the charcoal slurry coats the esophageal mucosa, which can obscure the view during a subsequent endoscopy, a procedure essential for grading the severity of injury [1].

*   Option 4: Insert a nasogastric tube for immediate gastric lavage. This is a dangerous intervention. Blind insertion of a nasogastric tube in the setting of a caustic ingestion can perforate the weakened, necrotic esophageal wall. Gastric lavage is not recommended for corrosive ingestions.

Clinical Reasoning and Evidence-Based Practice

The management of caustic ingestion is highly dependent on the severity of the injury, which is determined by endoscopic grading [1]. However, the immediate pre-hospital or emergency department nursing intervention focuses on stabilization and preventing further harm. The retrospective analysis of pediatric poisonings underscores that the acute phase of care requires preventing secondary injury from inappropriate interventions . The priority is to dilute the agent safely without inducing vomiting or causing additional trauma. The absence of oral burns does not rule out significant esophageal injury, so a cautious, non-invasive approach is paramount [1]. After this initial dilution, the child requires close monitoring and a prompt referral to a pediatric gastroenterologist for endoscopic evaluation, as access to this specialized care is a critical determinant of outcomes [1].References (research sources)

## 임상 시나리오

Corrosive Ingestion: Initial TriageImmediate Nursing Management for Alkali Exposure
For an alert child with no respiratory distress after ingesting a corrosive alkali like household bleach, the priority is dilution. Administer small sips of water or milk (up to 15 mL/kg) to reduce mucosal contact time and wash the substance from the esophagus.

Do not assume the absence of injury based on a lack of oral burns; significant esophageal damage can still be present. Continuous assessment of airway, breathing, and voice quality is critical.

CautionNever induce vomiting or perform gastric lavage. Vomiting re-exposes the mucosa to the caustic agent, and instrumentation risks perforation. Activated charcoal is ineffective and contraindicated.

## 핵심 개념

- **Liquefactive Necrosis** — A type of tissue death caused by alkaline substances (e.g., bleach) that saponify fats and dissolve proteins, leading to deep, rapid tissue penetration.
- **Sodium Hypochlorite** — The active chemical ingredient in household bleach, which is a caustic alkali that causes severe corrosive injury upon contact with mucosa.
- **Contraindication for Emesis** — A strict clinical guideline stating that vomiting should never be induced after ingestion of a corrosive substance due to the risk of re-injury and aspiration.
