A 4-year-old child presents to the emergency department with a barking cough, hoarseness, and mild inspiratory stridor that worsens at night. The child appears restless and prefers sitting up. What is the nurse's priority action?
1Examine the throat with a tongue depressor to visualize the epiglottis
2Place the child in a supine position to facilitate breathing
3Obtain a throat culture to identify the causative organism
4Keep the child calm and prepare for emergency airway management✓ 정답
해설
The priority is to keep the child calm and prepare for emergency airway management to prevent complete obstruction. Avoid interventions like throat examination or supine positioning that can worsen airway spasm.
Core Nursing ExplanationKey Concept Analysis: This question assesses the nurse's ability to recognize and prioritize care for a pediatric respiratory emergency: Croup (Laryngotracheobronchitis). The classic symptoms of barking cough, hoarseness, and inspiratory stridor that worsen at night are hallmark signs. The pathophysiology involves subglottic inflammation and edema, which narrows the airway. In a young child, even a small amount of swelling can lead to significant obstruction. The child's restlessness and preference for sitting up are signs of increased work of breathing and potential hypoxia. The priority is always maintaining a patent airway, which in croup means preventing agitation that can lead to crying and increased airway spasm.
Answer Rationale: Key Point! The nurse's priority action is to keep the child calm and prepare for emergency airway management. Agitation, crying, and struggling dramatically increase oxygen demand and can precipitate complete airway obstruction in an already compromised child. Preparing for emergency intervention (e.g., having oxygen, nebulized epinephrine, and intubation equipment ready) is a critical proactive step. Keeping the child with a parent in a position of comfort (often upright) is a key nursing intervention to reduce anxiety and respiratory effort.
Distractor Analysis:
Watch out for confusion! Option ①, examining the throat, is contraindicated in a suspected upper airway obstruction like croup. Forcing the mouth open with a tongue depressor can trigger severe laryngospasm and complete airway occlusion. This action is more associated with assessing for epiglottitis, which is a different, more rapidly progressive emergency.
Option ②, placing the child supine, is incorrect. The supine position can worsen respiratory distress by allowing the tongue and edematous tissues to fall back, further obstructing the airway. The child's natural preference for sitting up (tripod position) should be supported to maximize airway patency.
Option ③, obtaining a throat culture, is not a priority action during acute respiratory distress. It is an invasive procedure that would likely cause extreme agitation and crying, exacerbating the airway obstruction. Diagnostic tests are deferred until the airway is secure and the child is stable.
Related Concepts: Understanding the difference between croup and epiglottitis is critical for NCLEX. Both present with stridor, but the onset, appearance, and management differ significantly. Croup typically has a gradual, viral prodrome, while epiglottitis has a sudden, toxic appearance. Never visualize the throat in a child with suspected epiglottitis unless in a controlled setting like an operating room.
Concept Summary
• Disease: Croup (Laryngotracheobronchitis) – Viral inflammation of upper airway.
• Key Symptoms: Barking cough, hoarseness, inspiratory stridor (worse at night).
• Patho: Subglottic edema → narrowed airway → increased work of breathing.
• Priority Nursing Action: Maintain patent airway by minimizing agitation, providing humidified oxygen, preparing for emergency intervention.
• Positioning: Upright or position of comfort.
• Contraindicated Actions: Throat examination, separating child from parent, forcing supine position.
Side-by-Side Comparison!
Key Point! Do NOT examine throat. Prepare for immediate intubation in OR.
Anatomy, Physiology & Pharmacology Points
• Anatomy: The subglottic area (below vocal cords) in children is the narrowest part of the airway. Edema here causes disproportionate obstruction.
• Pharmacology: Nebulized racemic epinephrine is a rescue medication for moderate-severe croup. It causes vasoconstriction, reducing mucosal edema. Corticosteroids (e.g., dexamethasone) are given to reduce inflammation.
Memory Tips
• Mnemonic for Croup Symptoms: "Barking at the Moon" – Barking cough, symptoms Worse at Night.
• Priority Rule: ABCs (Airway, Breathing, Circulation). A crying, agitated child with stridor = Airway threat. Calm first!
• Don't Do It!: Remember: "Don't look down a stormy throat" – Avoid throat exams in croup/epiglottitis.
High-Frequency NCLEX Topics
Croup is a classic NCLEX pediatric emergency question. The exam tests your ability to: 1) Recognize the classic symptom triad, 2) Prioritize airway management and calming interventions, and 3) Identify dangerous actions to avoid (throat exam, supine position). Always think "safety first" and "prevent agitation."
Watch Out for Question Variations!
• Instead of asking for the priority action, the question might ask: "Which finding requires immediate intervention?" (Answer: Increasing stridor, retractions, cyanosis, lethargy).
• It might present a child post-nebulizer treatment and ask for evaluation: "Which finding indicates treatment is effective?" (Answer: Decreased stridor, quieter breathing, improved color).
• It could combine croup with drug administration: "The nurse is preparing nebulized epinephrine. Which client assessment is essential prior to administration?" (Answer: Heart rate, due to potential tachycardia side effect).
Nursing Clinical Practice GuideClinical Scenario: You are the triage nurse in the Pediatric ED. A father rushes in carrying his 4-year-old son, Leo. He reports Leo has had a cold for two days but woke up an hour ago with a harsh, barking cough and noisy breathing. Leo is clinging to his father, appears anxious, and has audible stridor when he inhales.Nursing Intervention Strategy:
1Immediate Assessment (Do NOT separate child from parent)Visually assess work of breathing – look for nasal flaring, sternal/intercostal retractions, use of accessory muscles. Note skin color. Listen for stridor without using a stethoscope near the face (to avoid agitation). Count respiratory rate.
2Priority Action – Calm & PositionSpeak in a soft, reassuring voice to both child and parent. Encourage the parent to hold Leo in an upright position on their lap. Provide a quiet, non-stimulating environment.
3Prepare & TreatApply pulse oximetry if it can be done calmly. Administer humidified oxygen via blow-by method (holding mask near face, not forcing it). Alert the healthcare provider and prepare for administration of nebulized medications (epinephrine, corticosteroids) as ordered. Have emergency airway equipment (size-appropriate endotracheal tubes, laryngoscope, suction) readily available at the bedside.
4Monitor & EvaluateContinuously monitor for signs of deterioration: increased stridor, retractions, agitation progressing to lethargy, cyanosis, or decreased oxygen saturation. Document response to interventions.
Patient Safety and Precautions:
• Absolute Contraindication: Do not attempt to visualize the throat or obtain a throat culture during the acute phase.
• Medication Caution: Nebulized epinephrine can cause tachycardia and hypertension. Monitor vital signs before and after administration.
• Discharge Education: If discharged, teach parents about cool mist humidifiers, taking the child into a steamy bathroom during a coughing spell, and when to return (trouble breathing, blue lips, extreme fatigue).
Nursing Procedure & Medication FlowProcedure for Managing a Child with Croup in ED:
1Triage & Immediate ActionRapid visual assessment → Place in "Respiratory Distress" protocol → Escort directly to treatment room with parent.
2PositioningUpright on parent's lap.
3Oxygen AdministrationHumidified O2 via blow-by at 2-6 L/min to maintain SpO2 > 92%.
4Medication Administration (as ordered)• Nebulized Epinephrine (Racemic or L-Epinephrine): Onset 10-30 min, duration 2-3 hours. Monitor for rebound edema.
• Dexamethasone (PO/IM): Single dose reduces inflammation over 6-24 hours.
5Ongoing MonitoringUse a croup score (Westley scale) to objectively assess severity and response.
A Word from Your Senior Nurse
"In the chaos of the ED, a scared child with a barking cough can make anyone's heart race. Your most powerful tool in this moment is not the medication drawer—it's your calm presence. Remember, your anxiety becomes their anxiety. By keeping the child with their parent, speaking softly, and moving deliberately, you reduce the physiological stress that is literally closing their airway. On the NCLEX, they are testing your clinical judgment under pressure: can you see past the 'tasks' (like getting a culture) to the real threat (a closing airway)? Master this mindset—protect the airway, prevent agitation—and you'll handle not just croup questions, but any pediatric emergency on the exam and in real life."
Croup — A common viral infection in young children causing inflammation and swelling of the subglottic airway, leading to a characteristic barking cough, hoarseness, and stridor.
Inspiratory Stridor — A high-pitched, crowing sound heard during inspiration, indicating partial obstruction of the upper airway (larynx or trachea).
Nebulized Epinephrine — A medication administered via mist for moderate to severe croup; it acts as a vasoconstrictor to rapidly reduce mucosal edema in the airway.
Subglottic Edema — Swelling in the area below the vocal cords, which is the narrowest part of a child's airway. This is the primary pathophysiological problem in croup.
Westley Croup Score — A clinical scoring tool used to assess the severity of croup based on level of consciousness, cyanosis, stridor, air entry, and retractions.
