Correct Answer is C
Explanation
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.
Correct Answer is A
Explanation
A. Provide humidified oxygen: This helps ease breathing and reduce airway irritation.
B. Allow the child to have a popsicle: Oral intake is contraindicated to prevent aspiration.
C. Obtain a throat culture: Invasive procedures like this can provoke airway spasm and are contraindicated.
D. Visualize the epiglottis using a tongue depressor: Direct visualization is avoided due to the risk of airway spasm and obstruction.
