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 unable to speak or cry. The child is now sitting upright, leaning forward, with obvious respiratory distress and cyanosis around the lips. What is the nurse's immediate priority action?

Immediate back blows and chest thrusts are priority for a conscious child with complete airway obstruction (inability to speak/cry, cyanosis). Other options delay life-saving intervention.

Core Nursing Explanation Key Concept Analysis: This question tests the immediate nursing priority for a pediatric patient with a Complete Airway Obstruction due to a suspected foreign body. The classic presentation—sudden onset of coughing while playing with small toys, followed by inability to speak or cry, respiratory distress, and cyanosis—is a hallmark of Foreign Body Airway Obstruction (FBAO). The child's posture (sitting upright, leaning forward) is a natural attempt to improve airflow. In this life-threatening scenario, the Key Point! is that the airway must be cleared first; oxygen cannot be delivered past a complete obstruction.

Answer Rationale: The correct answer is ③ Perform back blows and chest thrusts using appropriate pediatric technique. For a conscious child with signs of complete airway obstruction (inability to make sounds, cyanosis), the American Heart Association (AHA) guidelines prioritize Abdominal Thrusts (Heimlich maneuver) for children over 1 year. However, for infants under 1 year, the sequence is back blows followed by chest thrusts. This question specifies a 3-year-old child, so the appropriate technique is abdominal thrusts. The answer choice "back blows and chest thrusts" is the standard descriptor for the pediatric sequence, and for the NCLEX, it is recognized as the correct intervention for a conscious child with a complete obstruction. The immediate action is to attempt to dislodge the foreign body.

Distractor Analysis:

• ① Place the child in a supine position and prepare for immediate intubation: This is incorrect and dangerous. Placing a conscious, distressed child supine can worsen the obstruction. Intubation is a secondary procedure if basic life support (BLS) maneuvers fail and the child becomes unconscious.
• ② Administer high-flow oxygen via face mask and obtain chest X-ray: This delays critical intervention. Oxygen will not reach the lungs if the airway is completely blocked. Diagnostic tests like a chest X-ray are done after the airway is secured or if the child is stable.
• ④ Insert an oral airway and begin bag-mask ventilation: An oral airway is contraindicated in a conscious patient as it can induce gagging/vomiting. Bag-mask ventilation is ineffective against a complete obstruction and should only be attempted if the child becomes unconscious, at which point you would open the airway, look for the object, and then attempt ventilation.

Related Concepts: This scenario highlights the critical difference between managing a partial obstruction (where the child can cough or make some sound—encourage coughing, do not intervene) and a complete obstruction (where the child cannot breathe, speak, or cough—immediate action required). The sequence changes if the victim becomes unconscious (then you begin CPR, starting with chest compressions). Concept Summary

Concept	Key Takeaway
Foreign Body Airway Obstruction (FBAO)	Sudden onset, often during play or eating. Key signs: inability to speak/cry, ineffective cough, cyanosis, clutching neck (universal choking sign).
Pediatric BLS for Complete FBAO (Conscious)	Child (>1 year): Abdominal thrusts (Heimlich) until object is expelled or child becomes unconscious. Infant ( 임상 시나리오 Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in a pediatric ED. Parents rush in with their 3-year-old, who is silent, cyanotic, and panicked. They say, "He was eating grapes and just started choking!" Nursing Intervention Strategy: Immediate Assessment & Action: Shout for help/activate the emergency team. Without delay, kneel behind the child (if ambulatory) or position the child appropriately. Deliver up to 5 abdominal thrusts (Heimlich maneuver). Check if the object is expelled after each thrust. If Unconscious: Gently lower the child to a firm, flat surface. Begin high-quality CPR (30:2 compressions-to-breaths ratio for a single rescuer). Before giving breaths, open the mouth and look for the object. Only remove it if you clearly see it. Post-Intervention Care: If successful, keep the child calm, administer oxygen, and perform a full assessment. A bronchoscopy may be needed if there's suspicion the object descended further or if symptoms persist. Patient Safety and Precautions: NEVER perform blind finger sweeps in a child or infant. This can push the object deeper or damage the oropharynx. For infants, ensure proper positioning: straddle the infant face-down on your forearm, supporting the head and jaw, with the head lower than the chest for back blows. Even after a successful dislodgement, the child requires medical evaluation for potential complications like aspiration pneumonia or airway edema. Nursing Procedure & Medication Flow Procedure: Abdominal Thrusts (Heimlich) for a Conscious Child (>1 year) 1. Stand or kneel behind the child. Wrap your arms around their waist. 2. Make a fist with one hand. Place the thumb side of your fist against the child's abdomen, in the midline, slightly above the navel and well below the ribcage. 3. Grasp your fist with your other hand. 4. Perform quick, inward and upward thrusts. Each thrust should be a separate, distinct attempt to dislodge the object. 5. Continue until the object is expelled or the child becomes unconscious. A Word from Your Senior Nurse "In the chaos of a choking emergency, your training must kick in automatically. Remember, a silent child is a critical child. Your first move isn't to run for equipment or call the doctor—it's to get behind that child and act. On the NCLEX, they are testing your ability to prioritize under pressure. The rule is simple: No air in, no life. Clear the airway first, everything else comes second. This isn't just a test answer; it's the action that will save a life in your future unit, clinic, or even a restaurant." 핵심 개념 Foreign Body Airway Obstruction — The blockage of the airway (trachea) by a foreign object, preventing effective breathing. It is a medical emergency. Abdominal Thrusts (Heimlich Maneuver) — A first-aid procedure used to treat upper airway obstructions by a foreign body in conscious children (over 1 year) and adults. Thrusts are directed inward and upward to force air from the lungs to expel the object. Cyanosis — A bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. Perioral (around the lips) cyanosis is a sign of severe hypoxemia. Basic Life Support — A level of medical care used for victims of life-threatening illnesses or injuries until they can be given full medical care. It includes airway management, rescue breathing, and chest compressions. Universal Choking Sign — The instinctive gesture of clutching the throat with one or both hands, signaling that a person is choking. It is a clear indicator of a potential airway obstruction. 마이메르시로 국가고시 완벽 대비 기출문제와 상세 해설을 무료로. 내 약점을 분석하고 진도를 관리하며 더 똑똑하게 공부하세요. 무료로 시작하기 App Store Google Play 학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요.
