Which of the following is a common risk factor for falls among the elderly?

The correct response emphasizes the impact that certain medications can have on the elderly's balance and coordination. Many medications prescribed for various health issues can lead to side effects such as dizziness, sedation, or impaired cognitive function, all of which significantly increase the risk of falls. Elderly individuals often take multiple medications, which can compound these effects and further heighten their vulnerability to falls.

In contrast, high energy levels do not typically correlate with a risk of falls; rather, they are more likely to indicate physical well-being. Low calcium intake is relevant to bone health but does not directly cause falls; it increases the risk of fractures if a fall occurs. Regular exercise generally enhances strength, balance, and coordination, all of which are protective factors against falls, rather than risk factors. Understanding these aspects is vital for improving the safety and well-being of elderly individuals.
