Which of the following is a common change in the elderly population regarding sensation?

1. Increased pain response

2. Enhanced temperature regulation

3. Decreased thirst response

4. Improved vision

The correct answer is: Decreased thirst response

As individuals age, one of the notable changes in sensation is the decreased thirst response. This phenomenon is significant because it can lead to an increased risk of dehydration among the elderly. As the body ages, the mechanisms that trigger thirst become less effective, meaning older adults may not feel thirsty even when their bodies require fluids. This alteration can contribute to health issues, as adequate hydration is essential for maintaining various bodily functions. In contrast, the other options reflect changes that generally do not occur with aging. Increased pain response is not commonly observed; many elderly individuals experience a reduced sensitivity to pain. Enhanced temperature regulation is also unusual, as older adults may have a diminished ability to regulate body temperature. Lastly, improved vision is typically not seen with aging, as many seniors encounter deterioration in visual acuity and may develop conditions such as cataracts or macular degeneration. Understanding these changes is essential for providing appropriate care to the elderly population.
