Don't go back

Hello,

Imagine the following survey:

---page---
Q2
---page---
Q3
---page---
Q4
---page---

My question is:
If the user answer the Q3 and goes to Q4, I dont want the user can answer again (change the answser) of Q3, if the user go back the skip should go to Q2 and not to Q3.
It's possible?

Regards.
