Final answer:
Stridor would be the most concerning finding in a respiratory patient.
Step-by-step explanation:
Of the findings given, Stridor would be the most concerning in a respiratory patient.
Stridor is a high-pitched, wheezing sound that occurs when there is an obstruction in the airway, usually in the trachea or larynx. It suggests a potential blockage that can severely compromise breathing and may require immediate medical attention.
Intercostal retractions, altered mental status, and tachycardia are also important findings to consider, but Stridor indicates a more urgent and potentially life-threatening condition.
