At bedtime, a female client with dementia becomes increasingly confused and agitated because she believes that someone is standing behind the privacy curtain. Which action should the practical nurse (PN) take?

A. Administer a PRN antianxiety agent. - This should be a last resort due to potential side effects. Non-pharmacological interventions are usually preferable. B. Tell her no one is behind the curtain. - Arguing or contradicting her belief may escalate her agitation or confusion. C. Transfer the client to another room. - Moving her to a new environment might exacerbate her confusion and distress. D. Leave a night light on in her room. - This is a simple, non-intrusive intervention that can help reduce visual misinterpretations and provide comfort, potentially calming her agitation without confrontation or disruption.
