If a child is experiencing severe dehydration, which of the following signs may be observed?

In cases of severe dehydration, certain physiological signs become apparent due to the body's response to a lack of fluids. Observing sunken eyes is a key indicator, as dehydration causes the eyes to appear less full and more recessed. Additionally, the presence of cool, blotchy hands and feet can indicate that the body's circulatory system is prioritizing vital organs over extremities due to insufficient blood volume and fluid levels.

These combined symptoms illustrate a significant stress on the body as it attempts to maintain function despite the deficit in fluids. The other options describe scenarios that do not align with the signs of severe dehydration; hence they are not representative of what would typically be observed in such a condition.
