Answer to Question 1

ANS: C
Patients sometimes develop peripheral neuropathy, characterized by paresthesias, clumsiness, and muscle aches. If these occur, they may be reversed by administering pyridoxine (vitamin B6). It is not necessary to discontinue the isoniazid. Lowering the isoniazid dose and adding rifampin is not indicated. Rechecking the TST is not indicated.

Answer to Question 2

ANS: B
Isoniazid has an increased incidence of hepatotoxicity, especially when given with alcohol. Patients who consume alcohol or who have liver damage should receive isoniazid with caution and should have close monitoring of liver function. It is unrealistic to ask the alcoholic to stop drinking to undergo treatment. Rifampin is toxic to the liver, especially in alcoholics. Giving both drugs would only increase the risk of hepatotoxicity.
