An older adult client arrives at the emergency department presenting with confusion, agitation, and visual hallucinations. They have a history of chronic alcohol use and have not consumed alcohol for 48 hours. What condition is the client likely experiencing?

Rationale: A. Opioid withdrawal typically presents with symptoms such as yawning, muscle aches, diarrhea, sweating, and anxiety. Hallucinations and severe agitation within 48 hours are not characteristic, making this option less likely. B. Alcohol intoxication occurs when a person has recently consumed alcohol and typically presents with impaired coordination, slurred speech, and altered judgment. This client has not consumed alcohol for 48 hours, so intoxication is unlikely. C. Mild neurocognitive disorder involves subtle cognitive decline without significant disruption of daily functioning. Acute confusion, agitation, and hallucinations are inconsistent with this chronic, gradual condition. D. Delirium tremens is a severe form of alcohol withdrawal that usually occurs 48–72 hours after the last drink. It is characterized by confusion, agitation, visual hallucinations, autonomic hyperactivity (e.g., tachycardia, hypertension), and can be life-threatening if untreated. The client’s history and acute presentation strongly support this diagnosis.
