An older male client who is admitted to a rehabilitation facility manifests signs of acute dementia. The nurse observes the client repeatedly calling out for his deceased spouse to come and get him. Which intervention(s) should the nurse implement? Select all that apply.

A. Reorient the client while performing assessment: Reorienting a client with acute dementia during periods of distress can increase confusion and agitation. Forcing orientation is often counterproductive and may escalate anxiety. B. Lower the lighting in the client's room: Reducing harsh lighting can help decrease overstimulation and agitation, creating a calmer environment for a client experiencing acute confusion or distress. C. Switch to a familiar topic after acknowledging client's feelings: Validating the client’s emotions and then gently redirecting to familiar topics can reduce anxiety, provide comfort, and improve cooperation without causing confrontation. D. Remind the client that his spouse is deceased: Confronting the client with reality in a distressed state can increase agitation, fear, and confusion. Reality orientation should be approached cautiously, if at all, during acute episodes. E. Explain the rehabilitation regimen to the client: While education about care is generally important, a client in acute dementia may not be able to process detailed explanations. This intervention does not address immediate emotional distress or safety.
