Answer to Question 1

D
Patients with severe renal impairment may require a dosage reduction. Adding sodium bicarbo-nate would alkalinize the urine and increase memantine levels, causing toxicity. It is not neces-sary to discontinue or decrease the dose of the memantine with mild or moderate renal impair-ment.

Answer to Question 2

C
Alcoholics who are malnourished have a form of thiamine deficiency called Wernicke-Korsakoff syndrome, which is characterized by nystagmus, diplopia, ataxia, confusion, and short-term memory loss. Parenteral thiamine is indicated for treatment. Ascorbic acid is given to treat vita-min C deficiency, or scurvy. Pyridoxine is given for vitamin B6 deficiency, also common in al-coholics, but this patient does not have the symptoms of seborrheic dermatitis and peripheral neuropathy. Nicotinic acid is used for niacin deficiency, which is characterized by severe dry, rough skin.
