Which of the following is a sign of dehydration that should be reported to the nurse?

• A. Dry mucous membranes
• B. Increased appetite
• C. Clear skin
• D. Normal urine output

Answer: (A)

Dry mucous membranes signal that body fluids are running low, which is a common and important early sign of dehydration that should be reported so the nurse can assess fluid status and intervene. In contrast, increased appetite isn’t a typical dehydration sign, since dehydration tends to cause thirst rather than hunger. Clear skin suggests good hydration, not dehydration, and normal urine output does not fit dehydration, which often reduces urine production and makes urine more concentrated and darker. Reporting the dry mucous membranes helps prevent fluid and electrolyte problems.
