Which of the following actions can help prevent client falls?

Using a bath mat in a shower or tub is an effective action to help prevent client falls. Bath mats provide a non-slip surface that can significantly reduce the risk of slipping on wet surfaces, which is a common cause of falls in these areas. When clients step out of the shower or tub, a bath mat can create a safer transition from a wet, slippery surface to a drier one, promoting stability and support.

In contrast, lowering the seat on a toilet, while potentially beneficial for individuals with specific mobility issues, does not directly address fall prevention in other high-risk areas such as the bathroom floor. Having throw rugs on the floors can actually increase the risk of falls, as they can become tripping hazards if not secured properly. Using bright-colored paint on walls may enhance visibility or aesthetics, but it does not contribute to actual physical safety in preventing falls. Thus, the bath mat stands out as the most direct and practical measure to prevent falls in the context of home care.
