Limiting the number of times learners can jump to a slide

I have a slide that has three images - a beaver, a fox, and an owl. I want the learner to be able to click each image one time and jump to the corresponding slide one time.  Each image has the states of  "normal", "hover", and "visited."  Each image has the Trigger Wizard set to:

Action - Jump to slide

Slide - This is a quiz question specific to the image (for example, 9.4 We are all responsible for ensuring that information...)

When - User clicks

Object - The image (for example, Picture 4 - "Beaver3.png")

On Condition:

Picture 4 - "Beaver3.png" state is Normal

When I click on Beaver3.png, I jump to the slide with the question.  After I answer the question, I am returned to the main slide.  I can click on the image (e.g. Beaver3.png) again.  I'm sure there is way to limit this to one click. Help!!

Thanks!
