Answer to Question 1

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

D
Colchicine is used for prophylaxis when urate-lowering drugs, such as allopurinol, are initiated, because gouty episodes have a tendency to increase during this time. Patients start with both drugs, and ultimately the colchicine is withdrawn. Allopurinol does not affect the GI side effects caused by colchicine. Allopurinol may precipitate an acute gouty attack when treatment is begun; colchicine is given to prevent a gouty episode. Colchicine does not enhance the effects of allopu-rinol.
