Which is a normal age-related change observed in elderly residents?

1. Increase in physical strength

2. Decrease in taste sensation and smell

3. Heightened sensitivity to pain

4. Improved memory function

The correct answer is: Decrease in taste sensation and smell

A decrease in taste sensation and smell is indeed a common normal age-related change observed in elderly residents. As individuals age, it is typical for their sensory receptors to become less sensitive, which can lead to a diminished ability to taste and smell effectively. This change can impact appetite and enjoyment of food, as well as safety, since it may affect the ability to detect smoke or spoiled food. The other options offered do not accurately represent typical age-related changes. For instance, an increase in physical strength is not generally seen in the elderly, as aging often leads to muscle loss and reduced physical capabilities. Heightened sensitivity to pain is also not usual; older adults frequently experience reduced sensitivity to pain due to physiological changes. Lastly, improved memory function is contrary to what many experience, as cognitive decline may be common in elderly individuals, affecting memory and other cognitive functions. Therefore, option B is the most accurate regarding normal physiological changes associated with aging.
