## 문제

A 3-year-old child is brought to the emergency department with sudden onset of coughing, choking, and difficulty breathing after playing with small toys. The child is conscious but appears anxious and has stridor. What is the most appropriate initial nursing intervention?

## 보기

1. Position the child upright and encourage coughing while preparing for immediate medical intervention **✔ 정답**
2. Perform back blows and chest thrusts to dislodge the foreign body immediately
3. Place the child in Trendelenburg position to help expel the foreign body from airway
4. Administer high-flow oxygen via face mask and obtain a chest X-ray for diagnosis

**정답: 1**

## 해설

For a conscious toddler with partial airway obstruction (stridor, able to cough), the priority is to position upright and encourage coughing while preparing for emergency intervention. This supports natural cough reflex without risking conversion to complete obstruction.

Understanding the Clinical Scenario

This question presents a classic pediatric airway emergency. A 3-year-old child with sudden coughing, choking, stridor, and difficulty breathing after playing with small toys is highly suggestive of foreign body aspiration (FBA). The child is conscious and anxious, which is a critical detail. Stridor, a high-pitched sound heard on inspiration, indicates a partial obstruction of the upper airway. The immediate goal is to maintain a patent airway and prevent the partial obstruction from becoming complete.

Analysis of the Correct Answer (Option 1)

Position the child upright and encourage coughing while preparing for immediate medical intervention is the most appropriate initial nursing intervention. The rationale is grounded in the principle of "do no harm" and supporting the body's natural defense mechanism. For a conscious child with a partial airway obstruction who is still able to cough and breathe, the cough reflex is the most effective and safest mechanism for expelling the foreign body. Positioning the child upright uses gravity to assist, rather than hinder, the expulsion effort. Simultaneously, preparing for medical intervention—such as alerting a physician, preparing for an emergency bronchoscopy, and having emergency equipment ready—is essential because if the child's condition deteriorates (e.g., the cough becomes ineffective, respiratory distress worsens, or the child loses consciousness), immediate advanced life support is required. This approach aligns with the stepwise management framework highlighted in the educational review on airway foreign bodies, which emphasizes a systematic approach starting with clinical recognition and readiness for bronchoscopic removal [2].

Why the Other Options Are Incorrect

Option 2: Perform back blows and chest thrusts to dislodge the foreign body immediately.

This intervention is contraindicated in a child who is conscious and able to cough effectively. Performing back blows and chest thrusts on a child with a partial obstruction can cause the foreign body to shift and become a complete obstruction, a life-threatening event. These maneuvers are reserved for situations where the child cannot cough, breathe, or make sounds, indicating a severe or complete airway obstruction. The nursing intervention study on pediatric bronchoscopy underscores the importance of targeted, condition-specific interventions to prevent complications like hypoxemia, which can be precipitated by a complete obstruction .

Option 3: Place the child in Trendelenburg position to help expel the foreign body from airway.

The Trendelenburg position (head lower than feet) is not a standard or safe intervention for an upper airway foreign body. This position could cause the foreign body to migrate further up against the glottis, potentially worsening the obstruction or making it complete. It does not aid in expulsion and contradicts the physiological goal of using gravity to keep the object from moving proximally. The case report of a migrated foreign body illustrates the severe peribronchial inflammation and complications that can arise from a dislodged or impacted object, reinforcing the need to avoid maneuvers that could cause migration .

Option 4: Administer high-flow oxygen via face mask and obtain a chest X-ray for diagnosis.

While supplemental oxygen may be necessary if the child becomes hypoxemic, it is not the most appropriate initial intervention. The immediate priority is to help the child expel the foreign body through an effective cough. Applying a face mask could agitate an already anxious child, increasing oxygen consumption and the risk of dislodging the object. Furthermore, obtaining a chest X-ray, while part of the diagnostic workup for FBA, is a secondary step that delays immediate, potentially life-saving supportive care. The review on adult FBA notes that imaging is part of the work-up, but the clinical recognition and initial stabilization take precedence [2]. A chest X-ray can also be falsely negative, as many aspirated objects are radiolucent, and a delay in definitive management can lead to complications such as recurrent pneumonia, as highlighted in the case report .

Deep Dive into Pathophysiology and Nursing Priorities

The pathophysiology of FBA involves the object lodging in the larynx, trachea, or bronchus, triggering protective reflexes like coughing and laryngospasm. In a partial obstruction, turbulent airflow through the narrowed passage creates stridor. The body's inflammatory response can lead to edema, further compromising the airway. The goal-directed sedation nursing intervention study for pediatric bronchoscopy emphasizes the importance of maintaining physiological stability and comfort during airway procedures to prevent complications like hypoxemia (SpO₂

Managing Foreign Body Aspiration in a Conscious ChildSupporting Natural Airway Clearance
For a conscious child with a suspected partial airway obstruction (effective cough, stridor), the safest initial intervention is to position the child upright and encourage coughing. The cough reflex is the most effective mechanism for expelling the foreign body.

Simultaneously, the nurse must prepare for immediate medical intervention. This includes alerting the rapid response team, ensuring emergency airway equipment (e.g., suction, laryngoscope) is at the bedside, and preparing for an emergency bronchoscopy.

CautionDo not perform blind finger sweeps, place the child in a Trendelenburg position, or agitate the child with unnecessary procedures. If the cough becomes ineffective or the child loses consciousness, immediately initiate age-appropriate basic life support (BLS) maneuvers.

## 핵심 개념

- **Stridor** — A high-pitched, musical sound heard on inspiration, indicating a partial obstruction of the upper airway (larynx or trachea).
- **Foreign Body Aspiration (FBA)** — The accidental inhalation of an object into the airway, a common life-threatening emergency in young children, often presenting with sudden coughing, choking, and wheezing.
- **Partial Airway Obstruction** — A condition where the airway is not completely blocked; the person can still cough and breathe, and the effective cough reflex is the primary mechanism for clearing the obstruction.
- **Emergency Bronchoscopy** — A definitive medical procedure using a scope to visualize and remove a foreign body from the airway, typically performed under general anesthesia.
