Which observation indicates a potential issue in a child’s hydration status?

The observation that the child is breathing through their mouth indicates a potential issue in hydration status because mouth breathing can be a compensatory mechanism in response to dehydration or respiratory distress. When children are dehydrated, they may have a dry mouth and throat, leading them to breathe through their mouths instead of their noses. This can further exacerbate dehydration, as mouth breathing can cause additional fluid loss through increased evaporation in the respiratory tract.

Conversely, children who are playing actively are typically well-hydrated, as both hydration and energy are needed for physical activity. Regular bowel movements are also a sign of proper hydration, as adequate fluid intake helps maintain normal digestive function. A child's skin being warm and dry could indicate a variety of conditions, including potential dehydration, but mouth breathing serves as a more direct indicator of potential hydration concerns.
