The pediatric rapid response team is reviewing children with acute respiratory distress. Drag each cue cluster to the pattern it most strongly supports.

Quick answer
The correct classification requires distinguishing the phase and quality of abnormal breath sounds, the presence of focal versus diffuse findings, and the trajectory of respiratory effort. Upper-airway obstruction is supported by inspiratory stridor, a barky cough, and posturing that opens the airway. Lower-airway obstruction is supported by expiratory wheeze, prolonged expiration, and hyperresonance. Impending respiratory failure is supported by cyanosis, decreasing effort, and altered consciousness, regardless of the underlying cause.

Why this is correct
Each cue cluster contains overlapping features that could appear in more than one category. For example, a barky cough and inspiratory stridor are upper-airway findings, but subcostal retractions alone could also indicate lower-airway disease or impending failure. The key is to weigh the dominant pattern: inspiratory noise and airway-opening postures point to upper-airway obstruction; expiratory noise and hyperinflation point to lower-airway obstruction; and hypoxemia with reduced effort points to impending failure.

Clinical picture
In pediatric respiratory assessment, the phase of the abnormal sound is critical. Inspiratory stridor suggests narrowing at or above the thoracic inlet, while expiratory wheeze suggests intrathoracic airway narrowing. A silent chest with decreasing effort is an ominous sign of fatigue and impending respiratory arrest. Focal wheeze after a choking episode suggests foreign body aspiration, which may present with either inspiratory or expiratory sounds depending on the location of the obstruction.

Memory hook
Use the mnemonic 'UPPER-LOWER-FAIL': Upper airway = Inspiratory stridor, barky cough, drooling, tripod. Lower airway = Expiratory wheeze, prolonged expiration, hyperresonance. Failure = Cyanosis, decreasing effort, altered consciousness.

NCLEX decision rule
Classify by the dominant phase of the abnormal breath sound and the presence of systemic signs of hypoxemia or fatigue. Do not classify based on a single finding that is common to multiple categories.

Why the alternatives are wrong
If a cue cluster includes both inspiratory and expiratory sounds, determine which is more prominent and whether there are signs of impending failure. If a child has wheeze that improves with bronchodilators but still has tachypnea and retractions, the wheeze is lower-airway, but the persistence of increased work of breathing may indicate a need for closer monitoring rather than a different category.
