Which of the following is a true statement about assistive devices to aid older adults with impaired mobility?

A. A walker can be used when climbing stairs: Walkers are not safe for stair use, as they are unstable on steps and can lead to falls. Stair climbing requires handrails or other safer mobility strategies. B. Cane tips should be smooth: Cane tips should have rubber or nonslip surfaces to provide traction and stability. A smooth tip increases the risk of slipping and contributes to falls. C. Improper assistive device use contributes to older adult falls: Incorrect height adjustment, poor technique, or misuse of devices such as canes or walkers increases fall risk. Education and proper fitting are essential to ensure safety. D. Older adults save money by adopting assistive devices from their friends: Borrowing devices without professional fitting can result in poor alignment, discomfort, and instability. Assistive devices must be individualized to each person’s needs for safe and effective use.
