Which assessment finding in a child indicates potential dehydration?

Decreased urine output is a significant indicator of potential dehydration in a child. When a child is dehydrated, their body attempts to conserve water by reducing the amount of urine produced. Normal urine output can vary with age and fluid intake, but a noticeable decline in volume can suggest that the body is not adequately hydrated. Other signs of dehydration may include dry mucous membranes, increased thirst, and lethargy, but decreased urine output is a direct and measurable finding that clearly points to insufficient fluid levels in the body.

In contrast, weight gain typically indicates an increase in fluid retention or volume, which is contrary to dehydration. Increased energy levels would suggest adequate hydration and wellness, while bright, pink skin is generally associated with good hydration status and healthy circulation. Thus, decreased urine output serves as a reliable clinical sign of dehydration in children.
