Which statement about environmental safety indicates a need for further teaching?

The statement indicating a need for further teaching is the one about furniture being arranged so that it can be held onto for support. While it is true that ensuring furniture is easily accessible for support can aid in preventing falls, the statement lacks a critical safety component: it does not address the need to ensure that furniture is stable enough to support someone who may be relying on it for balance.

Proper environmental safety in a home involves not just the availability of support but also ensuring that the support systems, in this case, furniture, are safe to lean on. For instance, if a piece of furniture is lightweight or not securely anchored, it could topple over when someone tries to use it for balance. Hence, the arrangement should ideally promote both accessibility and stability, which is not clearly conveyed in that statement.

The other statements demonstrate a more comprehensive understanding of safety measures, such as installing grab bars, wearing appropriate footwear to prevent slipping, and removing potential tripping hazards like small rugs. Each of these emphasizes proactive steps to create a safer living environment.
