Question

Quizplus · Accepted Answer

Childhood asthma is typically characterized by reversible airflow obstruction, bronchial hyperreactivity, and inflammation. This can result in symptoms such as wheezing, coughing, and difficulty breathing. Option B describes acute respiratory distress syndrome (ARDS), which is not commonly seen in childhood asthma. Option C describes cystic fibrosis, which is a genetic disorder that affects multiple organs, but not specifically related to childhood asthma. Option D describes respiratory distress syndrome (RDS), which is typically seen in premature infants and is caused by a lack of lung surfactant. This is not associated with childhood asthma.
