A client who experiences memory loss is diagnosed with Wernicke encephalopathy caused by alcohol addiction. Which intervention is most important for the nurse to implement?

Choice A rationale: Individual addiction counseling may be beneficial for the client but does not address the immediate physiological issue of Wernicke encephalopathy. Thiamine replacement is the priority. Choice B rationale: Initiating disulfiram teaching is not relevant to the management of Wernicke encephalopathy. Disulfiram is used for alcohol aversion therapy, not thiamine deficiency. Choice C rationale: Thiamine administration is the most critical intervention for Wernicke encephalopathy caused by alcohol addiction. Thiamine deficiency is a key factor in the development of this condition. Choice D rationale: Nutrition referral may be important for the client's overall well being, but it is not the priority when the client is experiencing Wernicke encephalopathy. Immediate thiamine replacement is essential.
