A nurse is caring for a pre-school age child who has croup. Which of the following findings should the nurse report to the provider immediately?

A. Hoarseness: Hoarseness is a common symptom of croup and is usually not an immediate concern unless accompanied by other severe symptoms. B. Barky cough: A barky cough is characteristic of croup and is not an indication of immediate concern unless it worsens. C. Drooling: Drooling can be a sign of respiratory distress and difficulty swallowing, which can indicate a worsening condition such as epiglottitis, a more serious infection that can occur with croup. Drooling is a red flag and requires immediate medical attention. D. Paroxysmal attacks of laryngeal spasm at night: Paroxysmal attacks (episodes of severe coughing or difficulty breathing) are typical of croup, especially at night, but are usually self-limited and not an immediate cause for concern unless severe.
