Ingestion of poisons

A 2-year-old toddler is brought to the emergency department after ingesting an unknown amount of toilet bowl cleaner containing hydrochloric acid 30 minutes ago. The child is alert but drooling and complaining of mouth pain. What is the nurse's priority action?

1 Assess the child's airway and breathing status immediately ✓ 정답
2 Administer activated charcoal to absorb the poison
3 Induce vomiting to remove the remaining poison
4 Give milk or water to dilute the acid

해설

Airway assessment is the priority because acid ingestion can cause rapid swelling and obstruction. Other interventions like activated charcoal or inducing vomiting are contraindicated for caustic substances.

Priority Action for Acute Caustic Ingestion

The correct answer is to assess the child's airway and breathing status immediately. In any toxicological emergency, the initial priority is always the stabilization of the patient using the ABC (Airway, Breathing, Circulation) framework. This is especially critical in corrosive ingestion cases, where the primary threat to life in the acute phase is often airway compromise rather than systemic toxicity.

The child's presentation of drooling and mouth pain indicates direct tissue injury from the hydrochloric acid. This damage can rapidly progress to cause significant edema of the oropharynx, larynx, and epiglottis. Because a toddler's airway has a smaller diameter, even mild edema can drastically increase resistance to airflow and quickly lead to complete obstruction. The literature on acute corrosive poisoning highlights that progressive contact injury of deep tissues continues after the exposure, and managing the acute phase is fraught with controversy, but the immediate focus must be on life-sustaining functions ^[1]. Therefore, a rapid assessment of airway patency, respiratory rate, breath sounds, and oxygen saturation is the non-negotiable first step before any other intervention is considered.

The other options are contraindicated or represent secondary interventions:
- Administering activated charcoal is not effective for caustic substances and can obscure the view during subsequent endoscopy.
- Inducing vomiting is strictly contraindicated as it causes re-exposure of the damaged esophageal and oropharyngeal mucosa to the corrosive agent, significantly increasing the risk of perforation and worsening the initial injury.
- Giving milk or water for dilution is a secondary consideration that is no longer routinely recommended in many protocols due to the risk of inducing vomiting and the potential for generating heat with certain substances. Even if considered, it would only be performed after a thorough airway assessment confirms the patient's protective reflexes are intact.

The epidemiological data on caustic ingestion shows that outcomes can be severe, including death or long-term digestive sequelae ^[2]. The initial emergency management in any center, regardless of its specialization level, must prioritize the immediate life threats. Household product poisonings, such as those from toilet bowl cleaners, are a common presentation in emergency departments, and the clinical approach must be systematic, starting with the patient's hemodynamic and respiratory stability . The presence of drooling is a critical clinical sign that should immediately alert the nurse to the high probability of an evolving airway emergency.
