Which item would be the least effective in preventing client falls?

Throw rugs on floors are the least effective in preventing client falls due to their potential to become tripping hazards. While they may enhance the aesthetic of a room, they lack stability and can easily shift or slide when stepped on, increasing the risk of slips and falls. This makes them counterproductive in a home care setting where the safety of the client is paramount.

In contrast, items like bath mats in a shower or tub, handrails on stairs, and non-slip footwear provide substantial support and traction for individuals, significantly reducing the risk of falls. Bath mats offer a non-slip surface in wet areas, handrails provide stability and support when navigating stairs, and non-slip footwear enhances grip while walking. These features are specifically designed to address and mitigate the risks associated with falling, making them far more effective than throw rugs in ensuring a safe environment for clients.
