A 2-year-old is brought to the emergency department (ED) with a history of several days of rhinitis and now exhibits a productive barking cough and difficulty breathing. Which additional finding should alert the nurse that the child is experiencing respiratory distress?

A. A respiratory rate of 35 breaths/minute can be normal for a 2-year-old, so it is not necessarily indicative of distress by itself. B. Flaring of the nares is a sign of increased work of breathing and is an indication of respiratory distress, as the child is using accessory muscles to breathe. C. Diaphragmatic respirations are typical for young children and not indicative of distress unless other signs are present. D. Bilateral bronchial breath sounds do not necessarily indicate respiratory distress and could be normal depending on the context.
