A nurse is assessing a 4-year-old client admitted to the pediatric unit for respiratory distress. Which of the following findings should be addressed immediately?

Choice A rationale: Stridor during inspiration is a high-pitched, harsh sound caused by an upper airway obstruction. This is a critical finding that requires immediate attention, as it indicates compromised airflow potentially due to conditions like croup, epiglottitis, or foreign body aspiration. Left untreated, the obstruction can worsen, leading to severe hypoxia or respiratory failure. Prompt evaluation and intervention, such as securing the airway, are essential to ensure the child's safety and prevent life-threatening complications.

Choice B rationale: A wet, productive cough is typically associated with lower respiratory tract infections, such as bronchitis or pneumonia. While it warrants medical attention and treatment, it is not an immediate threat to the airway or oxygenation compared to stridor. Management often includes supportive care, hydration, and possibly antibiotics. However, this finding does not pose the acute risk that stridor represents in terms of respiratory distress and airway compromise.

Choice C rationale: A fever of 38.5°C (101.3°F) is a common finding in pediatric clients with infections. It indicates an inflammatory response to illness but is not immediately life-threatening. Fever management involves antipyretics, hydration, and monitoring for signs of more severe infection or sepsis. While elevated temperature requires attention, it does not carry the same urgency as stridor, which signals potential airway obstruction.

Choice D rationale: Irritability reported by the caregiver is a nonspecific symptom that may result from various causes, including pain, discomfort, or fever. While it suggests the child may be unwell, it does not directly indicate a critical condition or imminent danger. Monitoring and addressing the underlying cause of irritability are important, but this finding does not necessitate the same immediate response as stridor, which directly affects airway patency and oxygenation.
