Question 1

Which feature best distinguishes delirium from dementia in an older adult?

Accepted Answer

Sundowning refers to increased confusion, agitation, and behavioral disturbances that commonly occur in late afternoon and evening in patients with dementia.

Question 4

Which non-pharmacological intervention is most appropriate for managing agitation in a patient with moderate dementia?

Accepted Answer

Consistent routine, familiar music, and a calm environment

Answer

Consistent routines, familiar sensory stimuli like music, and a calm low-stimulation environment are evidence-based non-pharmacological interventions for dementia-related agitation.

Question 5

Lewy body dementia is distinguished from Alzheimer's disease by the presence of which hallmark feature?
