Which of the following is a potential indicator of respiratory distress?

Wheezing is a potential indicator of respiratory distress because it signifies that there is some degree of airway obstruction or narrowing, typically associated with conditions like asthma or bronchospasm. When the airways are constricted, the airflow becomes turbulent, causing the wheezing sound during breathing. This audible sign can indicate that the individual is struggling to breathe effectively, suggesting potential respiratory distress.

Normal skin color would typically indicate adequate oxygenation and circulation, which does not suggest distress. A persistent cough might indicate an underlying condition, but on its own isn’t a direct sign of immediate respiratory distress. A low heart rate is generally not associated with respiratory distress; rather, it might be indicative of other issues unrelated to respiratory function. Therefore, wheezing is the most direct indicator among the choices listed, as it clearly relates to compromised airway and respiratory function.
