What is a common symptom associated with dehydration in children?

Dry skin and mucous membranes are hallmark indicators of dehydration in children. When the body lacks sufficient fluids, the skin may lose its normal elasticity and moisture, leading to dryness. Similarly, mucous membranes, including those in the mouth and throat, can become dry and sticky, which is an important sign to assess during a clinical evaluation.

In children, dehydration can occur for various reasons, such as illness, fever, vomiting, diarrhea, or inadequate fluid intake. Recognizing dry skin and mucous membranes is critical because they can guide healthcare professionals in determining the severity of dehydration and the necessary interventions.

Edema of extremities typically indicates fluid overload rather than dehydration, while increased appetite is generally not associated with dehydration; instead, children might have a decreased appetite due to lack of fluids. Lethargy can occur due to dehydration, but hyperactivity is not commonly linked and could reflect other underlying issues. Thus, the choice highlighting dry skin and mucous membranes accurately reflects a common and significant symptom of dehydration in children.
