A nurse is teaching the family of a client who has Alzheimer's disease about safety interventions for nighttime wandering. Which of the following interventions should the nurse include?

A. Daytime naps can interfere with the natural sleep-wake cycle, potentially causing fragmented nighttime sleep. Disrupted nighttime sleep increases the likelihood of wandering and confusion in clients with Alzheimer’s disease. B. Installing locks at the bottom of exit doors can prevent the client from leaving unsupervised. However, this may also pose a risk of entrapment or delay emergency egress, which can compromise overall safety. C. Placing the mattress on the floor reduces the height from which the client could fall, decreasing the risk of injury during nighttime wandering. This intervention directly addresses the physical safety of clients prone to getting out of bed at night. D. Rubber-backed throw rugs can create uneven surfaces that increase the risk of tripping or slipping. For clients with impaired judgment or mobility, these rugs can inadvertently raise the chance of falls rather than prevent them.
