Which sign is commonly associated with dehydration?

• A. Edema
• B. Dehydration
• C. Hyperhydration
• D. Anemia

Answer: (B)

When the body loses more water than it takes in, you see signs of a water deficit. These signs reflect dehydration itself—dry mouth and mucous membranes, decreased skin turgor, concentrated (dark) urine, and sometimes dizziness or rapid heart rate. Among the options, the one that best fits is dehydration, because it directly describes the state you’re observing in someone who is fluid-deprived. The other choices point to conditions opposite to dehydration or unrelated issues: edema signals fluid overload with swelling; hyperhydration is excess body water; anemia is a blood condition not primarily about fluid balance.
