What is a common sign of potential dehydration in a resident?

1. Increased appetite

2. Dry skin and mucous membranes

3. Frequent small bowel movements

4. Low blood pressure

The correct answer is: Dry skin and mucous membranes

A common sign of potential dehydration in a resident is dry skin and mucous membranes. When the body is dehydrated, it loses water and essential fluids, leading to a decrease in moisture levels in the skin and mucosal tissues. This can result in the skin appearing less elastic, dry, and flaky. Mucous membranes, such as those in the mouth and nose, may also become dry and cracked, indicating insufficient hydration. Recognizing these signs is crucial for timely intervention to prevent further complications related to dehydration. Other signs of dehydration may include changes in urine output, increased thirst, and possible changes in blood pressure, however, dry skin and mucous membranes are among the most noticeable symptoms that can be easily observed.
