  1. Well, this question is kind of “defective” for lack of a better term and here is why; the question writer is expecting you to choose Flucytosine. But in real world, you never ever use flucytosine alone but the question is suggesting that very idea. Flucytosine, when used, is always part of a multi drug therapy. For the real test, USMLE would never asses your knowledge about Flucytosine the way this question is asking you. In the context of this question, Flucytosine must be a distractor rather than a correct choice! Just my two cents’ worth on this!
