Which symptom is commonly experienced by elderly clients related to dehydration?

1. Headaches

2. Thirst

3. Confusion

4. Dry skin

The correct answer is: Confusion

Confusion is a commonly experienced symptom of dehydration in elderly clients due to several factors associated with aging. As people age, their physiological responses to dehydration can change, leading to a decrease in the sensation of thirst, which often means older adults may not recognize when they need fluids. Additionally, dehydration can affect brain function and cognitive abilities, causing confusion or bouts of delirium. Elderly individuals are also more susceptible to dehydration due to factors such as medication side effects, chronic illnesses, and decreased kidney function. These changes can make it difficult for their bodies to conserve water and manage hydration levels effectively. While thirst is a common indicator of dehydration, older adults may not exhibit an adequate thirst response, making confusion a more significant symptom. Other symptoms, such as headaches, dry skin, or other cues, might also be present, but confusion stands out as a critical indicator that may require immediate attention to prevent further cognitive decline and complications.
