How to change screen once lives from the game are 0?

Hi.

We have been doing a game app in which the player should answer the given multiple choice questions correctly in order to heal a patient's body. If the player have made their lives meter 0, it will open to another screen that says they did not saved the patient. And also, when after finishing the questions but still have more than 0 lives left, they should also open to another screen but for victory. How can I create those? Thank you so much for those who will answer:) Here are my blocks and designer screen:
