A child with diarrhoea since 2 days shows the following sign. It is said to be very slow when it takes?
**Core Concept**
The question is related to the clinical assessment of dehydration in children, specifically the signs that indicate the severity of fluid loss. Dehydration can lead to various clinical manifestations, including changes in skin elasticity.

The correct answer is related to the sign of decreased skin elasticity, also known as skin turgor. When a child is dehydrated, the skin takes longer to return to its normal position after being pinched, indicating a loss of fluid from the tissues. This sign is particularly useful in assessing the severity of dehydration.
