An older adult client is admitted to the psychiatric unit for assessment of a recent onset of dementia. The nurse notices that in the evening this client often becomes restless, confused, and agitated. Which intervention is most important for the nurse to implement?

A. Ask family members to remain with the client in the evenings from 1700 to 2100: While family presence can offer comfort, it is not always feasible and doesn’t directly address the environmental management needed for sundowning behaviors. B. Administer a prescribed PRN benzodiazepine at the onset of a confused state: Though medications may help in acute cases, routine pharmacologic management is not the first-line intervention due to risks like oversedation and increased fall risk in older adults. C. Postpone administration of nighttime medications until after 2300: Delaying medications may interfere with sleep hygiene and the efficacy of routine medications that aid in rest or symptom management. D. Ensure that the client is assigned to a room close to the nurses' station: Proximity to staff allows for more frequent monitoring and faster intervention during episodes of confusion, helping prevent injury and manage behaviors associated with sundowning.
