A 3-year-old child is brought to the emergency department by parents who report that the child was playing with small toys and suddenly began coughing violently, then became quiet but is now having difficulty breathing. What is the nurse's priority action?
The child appears anxious, is sitting upright, and has decreased breath sounds on the right side with inspiratory stridor.

해설
In partial airway obstruction from foreign body aspiration, keeping the child calm in a comfortable position prevents complete obstruction while preparing for definitive removal. Back blows/chest thrusts or intubation could worsen obstruction, and oxygen alone is insufficient.
Understanding the Clinical Presentation
The child’s history of playing with small toys, followed by sudden violent coughing and subsequent quiet period with respiratory difficulty, strongly suggests foreign-body aspiration (FBA). The unilateral decreased breath sounds on the right side indicate that the object has likely lodged in the right main bronchus, causing a ball-valve or complete obstruction. The child’s anxiety and upright posture are compensatory mechanisms to maximize airway patency. This is a life-threatening pediatric emergency, as FBA is a leading cause of accidental death in children [3].
Why the Priority is to Minimize Distress and Prepare for Intervention
The child is conscious, maintaining an airway independently, and breathing, albeit with difficulty and stridor. The priority nursing action is to avoid any intervention that could worsen the obstruction or increase oxygen consumption. Agitating the child through procedures like back blows, forced oxygen mask application, or attempts at intubation without preparation can cause crying, which may dislodge the object into a more precarious position (e.g., complete laryngeal obstruction) or increase metabolic demand in an already hypoxic state. Allowing the child to remain in a position of comfort reduces anxiety and oxygen consumption while the team prepares for definitive management, which is rigid bronchoscopy under controlled conditions in the operating room or emergency department [3].
Analysis of Incorrect Options
Option 1 (Initiate back blows and chest thrusts without delay) is contraindicated in a conscious child with an effective, albeit compromised, cough. Blind finger sweeps and abdominal thrusts are also not recommended for young children as they can cause trauma or convert a partial obstruction into a complete one. These interventions are reserved for a child who becomes unconscious or has a severe, ineffective cough with complete airway obstruction.
Option 2 (Prepare for urgent endotracheal intubation now) is a high-risk intervention in this scenario. If the foreign body is in the left main bronchus, intubation could push it further down or convert a partial obstruction to a complete one. More critically, positive pressure ventilation in the setting of a complete unilateral main bronchial obstruction can lead to overdistension of the contralateral lung, causing barotrauma and precipitating a tension pneumothorax, a rapidly fatal complication . Definitive airway management is rigid bronchoscopy, not endotracheal intubation.
Option 3 (Provide high-flow oxygen through a face mask) is a supportive measure but not the priority action. Forcing a mask on an anxious, upright child can cause significant distress, crying, and increased oxygen consumption, potentially worsening respiratory failure. Oxygen can be provided via a "blow-by" method held by the parent, but the immediate priority is to keep the child calm and prepare for definitive removal. The risk of acute hypercapnic respiratory failure, as highlighted in similar cases, necessitates prompt preparation for bronchoscopic removal rather than reliance on supportive oxygenation alone [3].
Nursing Implications and Clinical Reasoning
The core nursing principle in pediatric FBA with a partially obstructed airway is "do no harm" by minimizing agitation. The nurse's role is to create a calm environment, allow the parent to comfort the child in their preferred position, and rapidly assemble the necessary personnel and equipment for emergency bronchoscopy. Post-procedure, targeted nursing interventions are crucial to monitor for airway complications such as hypoxemia (SpO₂ <90%), bronchospasm, and laryngeal edema, which are known complications following pediatric bronchoscopy . The integration of advanced imaging and risk assessment tools is an evolving area for prevention, but the immediate clinical management remains focused on stabilization and controlled removal .

Pediatric Foreign Body Aspiration: Initial ManagementPrioritizing safety in a conscious child with partial airway obstruction
Do not agitate a child with a suspected foreign body aspiration who is conscious and maintaining an airway. Crying can dislodge the object into a complete laryngeal obstruction or increase oxygen demand.
Allow the child to remain in a position of comfort (often sitting upright) to reduce anxiety and work of breathing while the team prepares for rigid bronchoscopy under controlled conditions.
Caution
Back blows and chest thrusts are contraindicated in a conscious child who can cough or breathe. Forced oxygen masks and unnecessary airway manipulation can worsen the obstruction.
Foreign Body Aspiration (FBA) — Inhalation of an object into the respiratory tract, a leading cause of accidental death in children, often presenting with sudden coughing, stridor, and unilateral decreased breath sounds.
Inspiratory Stridor — A high-pitched, harsh sound heard during inspiration, indicating a partial obstruction of the upper airway or trachea.
Rigid Bronchoscopy — The definitive diagnostic and therapeutic procedure for removing aspirated foreign bodies from the airway, performed under general anesthesia.
Ball-Valve Obstruction — A type of partial airway obstruction where air can enter the lung on inspiration but becomes trapped on expiration, leading to hyperinflation of the affected side.
