Jacob, I understand your comments but I do feel there are times that you simply need to be honest with your students and if you do not know the answer to a question, simply let them know you do not know but you will find out and get back with them. No one can know everything so if a topic comes up that was not a primary focus of the course but a student is asking a question in a related area, not knowing is not the problem, rather the willingness to get the information to the student and let them know how you researched the question is a true teachable moment.
