Hi Sue,
If I'm understanding you correctly, you'd like to have feedback for the one initial question, then go through the rest of the quiz questions with no feedback until the end. Is that correct?
At this time, Quizmaker is not able to set different feedbacks for individual questions within a quiz. If you'd like to see that feature in future builds, you can suggest it here:

If you wanted to get really creative, you could use Presenter to embed two separate quizzes- each with unique feedback settings- and then use Dave Moxon's blog to help you track both quizzes in the same presentation using Articulate Online.
Good luck!
