A nurse is caring for a client who has Wernicke-Korsakoff psychosis as a result of chronic alcohol use disorder. Which of the following interventions should the nurse anticipate?

D. Wernicke-Korsakoff psychosis is a neurological disorder caused by thiamine (vitamin B1) deficiency, often resulting from chronic alcohol use disorder. Thiamine deficiency can lead to significant neurological impairments, including confusion, ataxia, and memory deficits characteristic of Wernicke's encephalopathy and Korsakoff's psychosis.

The primary intervention for Wernicke-Korsakoff psychosis is the administration of thiamine supplementation. Thiamine replacement therapy is essential to prevent further neurological deterioration and to potentially reverse some of the cognitive deficits associated with the disorder.

The other options are not directly related to Wernicke-Korsakoff psychosis:

A. Monitoring for the presence of esophageal varices is more relevant to complications of chronic liver disease, such as cirrhosis, commonly seen in individuals with alcohol use disorder, but not specific to Wernicke-Korsakoff psychosis.

B. Placing the client in protective isolation is not indicated for Wernicke-Korsakoff psychosis. Protective isolation is typically used for clients with compromised immune systems to reduce the risk of infection.

C. Laboratory analysis of cardiac enzymes is typically performed to assess for myocardial injury or infarction, which is not directly associated with Wernicke-Korsakoff psychosis.
