When a weak client is positioned in a chair, what is an important action for the nurse aide?

Positioning a weak client in a chair requires careful consideration of their safety and comfort. Placing the signaling device within the client's reach is crucial because it empowers the client to call for assistance if needed. This is especially important for weak clients who may have difficulty getting up or alerting staff without help. Ensuring they can easily access the signaling device promotes their independence and safety.

In terms of the other actions, while securing a client with a seatbelt can be beneficial in certain circumstances, it is not universally required or the most immediate concern. Pushing the chair against the wall may limit mobility and create a safety hazard if the client needs to move or get up. Keeping a light on for visibility is helpful, but it does not directly address the immediate needs of the client in terms of assistance access. Thus, having the signaling device close at hand is the most effective and supportive action in this scenario.
