Which statement about dehydration risk factors in older adults is most accurate?

• A. Reduced thirst perception
• B. Regular hydration helps prevent dehydration
• C. Monitor for dehydration signs regularly
• D. Avoiding all fluids is not a preventive strategy for dehydration

Answer: (A)

In older adults, a common risk factor for dehydration is a reduced sense of thirst. Aging can blunt the body’s drive to drink, so individuals may not feel thirsty even when they need fluids. That means their daily fluid intake can become inadequate, increasing the chance of dehydration. This directly identifies a physiological change that raises risk, which is why it’s the best choice. The other statements describe things that help prevent or manage dehydration rather than factors that raise risk. Regular hydration is a protective practice, not a risk factor. Monitoring for dehydration signs is about detection and early care, not a risk factor. Avoiding all fluids is unsafe and not a preventive strategy.
