Which assessment finding indicates a potential airway obstruction in a child?

The presence of drooling and stridor in a child is a significant assessment finding that indicates a potential airway obstruction. Drooling suggests that the child may have difficulty swallowing, which can occur with swelling or irritation in the throat or airway. Stridor, on the other hand, is a high-pitched, wheezing sound caused by disrupted airflow in the upper airway, typically due to obstruction or narrowing. This combination can indicate conditions such as croup or epiglottitis, both of which can lead to serious airway compromise if not addressed promptly.

The other options present signs and symptoms that, while they may indicate respiratory issues, do not directly suggest a critical airway obstruction. For example, a barky cough and mild intercostal retractions may indicate mild respiratory distress, possibly related to croup, but do not necessarily confirm significant airway obstruction. Similarly, fever with thick secretions can indicate an infection but does not inherently imply an obstructed airway. Lastly, a hoarse cough and restlessness could signal distress or inflammation but are not clear indicators of obstruction in the airway. Thus, drooling and stridor are the most concerning findings related to potential obstruction in the airway.
