Which of the following is a common method for alleviating symptoms in children with croup?

Cool mist therapy is commonly recommended for alleviating symptoms in children with croup because it helps to soothe the airways and reduce respiratory distress. The cool mist can provide relief by moisturizing the upper airway, which can reduce irritation and swelling, leading to improved breathing. This non-invasive approach can be easily administered and is beneficial for children who are experiencing mild to moderate croup symptoms.

In contrast, long-term antibiotics are not effective for croup since it is usually caused by a viral infection, and antibiotics are not indicated. High-dose steroids may be used in some cases, particularly for severe croup, but they are not the first line of treatment for most children. Immediate hospitalization is typically reserved for severe cases of croup where the child is in significant respiratory distress or showing concerning signs such as stridor at rest, and is not necessary for milder cases where home treatment options, like cool mist therapy, may be sufficient.
