Which is a sign of respiratory distress in a child?

Leaning forward, also known as the tripod position, is a common indicator of respiratory distress in children. When a child leans forward, it often suggests that they are struggling to breathe and are trying to maximize their airway patency. This position can help facilitate easier breathing by using gravity and allowing for better expansion of the chest cavity. It is an instinctive behavior that indicates the child is experiencing difficulty in obtaining adequate air.

In contrast, normal alertness, soft coughing, and a calm demeanor do not typically signify respiratory distress. A child who is alert and calm may not be experiencing significant respiratory challenges. Soft coughing may indicate an upper respiratory issue, but on its own, it does not necessarily reflect the severity of respiratory distress compared to physical signs like leaning forward.
