What symptom might indicate that Holly is dehydrated?

Dry mucous membranes are a classic sign of dehydration. When the body does not have enough fluid, it prioritizes maintaining blood volume and pressure, often leading to decreased saliva production and moisture levels in mucous membranes. This dryness can be visibly noted in areas like the lips, inside the cheeks, and the nasal passages.

Other options suggest conditions that are either normal or indicative of hydration. Bright eyes typically signal adequate hydration, as dehydration can lead to sunken eyes. Increased urination often reflects adequate hydration as well, considering that the body is adequately expelling excess fluids. Normal skin turgor indicates effective hydration, as it shows that the skin is adequately elastic and not losing moisture. Each of these elements contrasts the clear signs of dehydration represented by dry mucous membranes.
