What are common early signs of asthma in children?

The selection highlighting dyspnea and increased secretions as common early signs of asthma in children is appropriate because asthma is primarily characterized by airway inflammation and bronchial hyperreactivity, which can lead to difficulty breathing (dyspnea) due to narrowed airways. Increased secretions, such as mucus production, can also occur as the body attempts to protect the airways and respond to irritation.

In children, asthma symptoms frequently manifest as shortness of breath during physical activity or exercise, wheezing, and coughing, particularly at night or early in the morning, all of which align with dyspnea. Additionally, as the airways become inflamed, the production of mucus increases, which can contribute to airway obstruction and exacerbate breathing difficulties.

The other options do not directly align with the typical early signs of asthma. Rapid heart rate and fever can indicate infections or other health issues rather than asthma itself. Chest tightness and decreased breath sounds may occur in more severe or advanced cases of asthma, not necessarily as early signs. Skin rash and vomiting are not common indicators of asthma; rather, they can be associated with allergic reactions or other conditions.
