Which finding suggests dehydration?

Which finding suggests dehydration?

• A. Edema
• B. Swelling of ankles
• C. Jaundice
• D. Dry mucous membranes

Answer: (D)

Dehydration occurs when total body water is reduced, so tissues that normally stay moist lose moisture as well. Dry mucous membranes reflect this loss of moisture in the oral and airway surfaces and are a classic sign of dehydration. In contrast, edema or swelling of the ankles indicates excess fluid in the body’s tissues, not a deficit, and jaundice points to liver or biliary problems rather than hydration status. So the presence of dry mucous membranes best signals dehydration.
