How to have a custom changing header in a Record Type

I am working on an interview application and one of the features is to edit previous questions. I was tasked with having the header display the current question and answer given when you click on the question's ID. My problem is I'm not sure how to create this type of header. Any help with the code would be great! I know it needs to be done in the views and header section of the record type but I'm not sure exactly what to put. Any help is appreciated!
