What factors increase the risk of a traumatic brain injury (TBI) for an unsteady older adult?

The correct answer highlights the important consideration of physical limitations that come with conditions like rheumatoid arthritis, which can lead to gnarled hands and feet. For older adults, such physical impairments can contribute to unsteadiness, making them more vulnerable to falls and subsequent traumatic brain injuries (TBI). The inability to grasp objects firmly or maintain balance can significantly increase the risk of falling.

While other factors also contribute to the risk of TBI in older adults, they either do not specifically relate to unsteadiness or serve more as safety precautions rather than risk factors. Grab bars, for instance, are designed to enhance safety and stability, while poor lighting and throw rugs can create hazards but would not inherently affect the physical ability to maintain balance as directly as the physical changes associated with rheumatoid arthritis. Understanding these connections is crucial for assessing fall risks and implementing effective preventive measures for older adults.
