For the quiz above, when I read the textbook I find that either vancomycin or fidaxomicin can be used as first line for initial episodes. Yet the correct answer is vancomycin, fidaxomicin being one of the wrong choices. Is there an error in the question or my understanding of the question?
Both my first post and this one seem similar in nature. Is there a tag or a specific discussion board where I should post such questions in the future?
