Final answer:
The nurse should accompany the client during walks to ensure their safety. They should not lock the client in their room or restrict access to the halls, and could provide a walking aid if needed.
Step-by-step explanation:
To ensure the client's safety while walking in the halls, the nurse should accompany the client during walks. This approach allows for supervision to promptly address any issues, such as falls, that could arise due to a shuffling walk, often associated with dementia. The client should not be locked in their room nor should their access to the halls be restricted, as freedom of movement is important for their mental health. Providing the client with a walking aid may also be beneficial if the individual has mobility issues. By using these strategies, nurses can create a balance between the client's safety and their need for independence and dignity.
