Which of the following are signs of dehydration that caregivers should look for in residents?

Recognizing signs of dehydration is critical in caregiving, especially for older adults who may be at greater risk. Dry mouth and dizziness are key indicators of dehydration. A dry mouth occurs when there is inadequate moisture in the mouth due to insufficient fluid intake, leading to discomfort and difficulty swallowing. Dizziness can arise from a drop in blood volume caused by dehydration, affecting blood circulation and leading to a sense of lightheadedness or unsteadiness.

In contrast, while increased appetite and fatigue may suggest other health issues, they are not specific signs of dehydration. High blood pressure and sweating are also not accurate indicators; in fact, sweating can sometimes lead to dehydration rather than signal it. Increased urination and energy would not typically align with dehydration either; increased urination can actually indicate excess fluid intake or other health problems. Therefore, the identification of dry mouth and dizziness as signs of dehydration is essential for caregivers to monitor the health of residents effectively.
