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?

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.

Clinical Priority in Pediatric Croup

The child's presentation—barking cough, hoarseness, and worsening nighttime inspiratory stridor with a preference for an upright posture—is classic for acute laryngotracheobronchitis (croup). In the NCLEX-RN framework, this scenario falls under the Physiological Integrity and Safe and Effective Care Environment client need categories, specifically assessing the nurse's ability to prioritize care in a potentially life-threatening respiratory condition.

The priority action is to keep the child calm and prepare for emergency airway management. Agitation and crying increase oxygen consumption and can worsen dynamic airway obstruction, potentially converting a partial obstruction into a complete one. The pathophysiological basis is subglottic edema and inflammation, which narrows the pediatric airway at its most vulnerable point, the cricoid ring. Any further increase in negative intrathoracic pressure from vigorous respiratory effort or crying can collapse this already compromised airway.

The other options are incorrect and potentially dangerous. Examining the throat with a tongue depressor to visualize the epiglottis is contraindicated in a child with stridor and a croup-like presentation unless in a controlled setting (e.g., the operating room) with personnel capable of securing a difficult airway, as it can trigger laryngospasm and complete obstruction. This action is more directly associated with the risk of precipitating a crisis in acute epiglottitis, but the principle of avoiding unnecessary oropharyngeal stimulation in any child with significant upper airway obstruction is a critical safety point. Placing the child in a supine position is incorrect because it can exacerbate airway obstruction; children with croup naturally assume a position of comfort, often sitting up or being held by a parent, which helps maintain airway patency. Obtaining a throat culture is not a priority in the acute phase of respiratory distress; the immediate need is assessment and stabilization of the airway, breathing, and circulation (ABCs), not diagnostic testing.

The management of croup is centered on reducing airway edema. The provided evidence underscores the role of glucocorticoids as the mainstay of treatment ^[2]. While the first study specifically investigated nebulized budesonide and found a significant improvement in symptoms, the broader Cochrane review confirms the effectiveness of glucocorticoids in treating croup in children [1, 2]. The nurse's role in preparing for emergency airway management includes ensuring the availability of these medications (such as nebulized budesonide or systemic dexamethasone), along with nebulized racemic epinephrine for severe cases, and setting up equipment for potential intubation if the child's condition deteriorates. Clinical assessment, often guided by croup scores that evaluate items such as stridor, level of consciousness, and air entry, is essential for monitoring response to treatment, although the reliability of these scores in a busy emergency department can be variable . The nurse must continuously observe for signs of increasing respiratory failure, such as stridor at rest, retractions, and a decreasing level of consciousness, which signal the need for immediate escalation of care .
