A nurse is collecting data from the family members of a client who has Alzheimer's disease. Which of the following findings should the nurse identify is the priority and requires immediate intervention?

A. Social withdrawal: Social withdrawal is common in Alzheimer's disease and may indicate depression or disease progression. While important to address, it does not pose an immediate safety risk. B. Inability to remember their partner’s name: Memory loss is a hallmark of Alzheimer's disease. Forgetting familiar names requires monitoring and supportive strategies but is not an urgent safety concern. C. Difficulty articulating words: Language difficulties can affect communication and quality of life, but they do not immediately endanger the client. Interventions focus on speech therapy and alternative communication methods. D. Wandering outside at night: Wandering exposes the client to hazards such as getting lost, traffic accidents, or injury, making it a priority safety concern. Immediate intervention is necessary to protect the client and prevent harm.
