Which of the following is a sign of dehydration?

1. Increased energy

2. Low blood pressure

3. High appetite

4. Moist skin

The correct answer is: Low blood pressure

Low blood pressure is a sign of dehydration because when the body loses fluids, either through excessive sweating, vomiting, diarrhea, or insufficient fluid intake, it can lead to a decrease in blood volume. A lower blood volume can result in reduced blood pressure as there is less fluid to circulate through the blood vessels. This can lead to symptoms such as dizziness or fainting, especially when standing up quickly. In contrast, increased energy, high appetite, and moist skin are generally associated with well-hydrated states. Increased energy and high appetite suggest that the body is functioning optimally with adequate fluids and nutrition, while moist skin indicates good hydration levels. Dehydration typically results in dry skin, fatigue, and decreased appetite, highlighting the importance of maintaining proper fluid balance for overall health.
