What is the best initial approach when a patient with vascular dementia demonstrates unsafe wandering at nighttime?

A. Environmental modifications are the least restrictive and safest first approach for managing wandering in patients with dementia. Examples include securing exits, adding nightlights, using door alarms, and removing tripping hazards. These interventions reduce risk of injury while respecting the patient’s autonomy and dignity. B. Administering sedative medications may be considered only if nonpharmacologic strategies fail, due to risks of oversedation, falls, and worsening cognitive impairment. Sedatives are not the first-line intervention. C. Increasing daytime activities can help reduce restlessness and nighttime wandering, but it is a supportive measure rather than an immediate safety intervention. It works best in combination with environmental modifications. D. Physical restraints should be avoided unless there is an immediate threat to the patient’s safety and all less restrictive measures have failed. Restraints carry significant risks, including injury, agitation, and psychological distress.
