A nurse is collecting data from the caregiver of a client who has Alzheimer's disease. The caregiver reports the client has difficulty sleeping at night and wanders throughout the house. Which of the following interventions should the nurse recommend?

As a nurse, the intervention that should be recommended is encouraging the client to take frequent walks during the day. This will help the client expend some energy and reduce the restlessness that could be causing the sleep disturbance at night. The other options are not recommended because barbiturate medications can cause excessive sedation, allowing the client to nap for at least 1 hour during the day can interfere with their ability to sleep at night, and putting a lock on the client's door can be a safety risk in case of an emergency.
