Final answer:
The correct answer is D.) The nurse should review the client's serum level of Thiamine (Vitamin B1) when assessing memory dysfunction in a client with chronic alcoholism due to the risk of deficiency leading to serious brain conditions.
Step-by-step explanation:
When assessing a client diagnosed with chronic alcoholism for potential memory dysfunction, it is important to review the client's serum level of Thiamine (Vitamin B1). Chronic alcoholism can lead to a thiamine deficiency, which can cause serious brain conditions such as Wernicke's encephalopathy, as well as other health issues like Beri-Beri. Thiamine is essential for the proper functioning of the nervous system and is crucial for carbohydrate metabolism, where its deficiency can lead to the accumulation of metabolites such as pyruvate and lactate, particularly affecting brain cells.
