A nurse is providing teaching to the caregiver of an older adult client who has Alzheimer's disease and is being cared for at home. The client wanders at night and has a history of previous falls. Which of the following instructions should the nurse include in the teaching? (Select all that apply.)

A. Installing locks at the top of doors is a safety measure to prevent wandering at night. It ensures that the client cannot easily open the door and leave the house. B. Positioning the mattress on the floor helps prevent injury from falls by eliminating the risk of the client falling from a height while in bed. C. Encouraging physical activity can help promote better sleep, but it should be done earlier in the day. Excessive stimulation right before bedtime could have the opposite effect. D. Installing sensor devices on outside doors alerts caregivers when the client attempts to leave the house, which is important for preventing wandering. E. Placing the client in a reclining chair is not recommended as a safety measure for wandering and could be uncomfortable, limiting the client's mobility and ability to rest properly.
