A nurse is reinforcing teaching with the caregiver of a client who has Alzheimer's disease.The caregiver reports that the client awakens at night and wanders.Which of the following strategies should the nurse suggest?

Choice A rationaleEncouraging the client to nap during the day might disrupt their sleep-wake cycle further, potentially increasing nighttime wandering. Daytime napping can reduce the need for nighttime sleep in individuals with Alzheimer's disease.Choice B rationaleAdministering an antianxiety medication before bedtime may sedate the client but does not address the underlying cause of the nighttime wandering and can have side effects, including increased confusion and risk of falls in older adults.Choice C rationalePlacing a lock at the top of doors leading outside is a crucial safety measure for clients with Alzheimer's disease who wander at night. This prevents them from leaving the home unsupervised and potentially getting lost or injured.Choice D rationaleUsing light restraints while the client is in bed is generally not recommended and should be a last resort due to ethical and safety concerns. Restraints can increase agitation and anxiety and may cause physical harm.
