What is a common sign of dehydration in elderly residents?

1. Increased blood pressure

2. Increased appetite

3. Dark yellow urine

4. Unexplained weight gain

The correct answer is: Dark yellow urine

Dark yellow urine is a common sign of dehydration, particularly in elderly residents. When the body is dehydrated, the kidneys conserve water, resulting in urine that is concentrated and darker in color. This change in urine color can be an important indicator for caregivers to monitor, as it often reflects the individual's hydration status. In older adults, dehydration can occur more easily due to factors such as decreased fluid intake, medications, and health conditions, making it essential for caregivers to recognize this sign. The other options, such as increased blood pressure or appetite, do not typically align with dehydration symptoms, and unexplained weight gain can be related to fluid retention or other health issues, rather than a sign of dehydration. Thus, dark yellow urine stands out as a clear indication of inadequate fluid intake in elderly individuals.
