Bahrain Multiple Entry Visa- Exit Re-entry Question

Hi,
I have a multiple entry visit visa for bahrain which is valid for three months. My base country is Pakistan, I want to exit and then re-enter bahrain. My question is do I have to go back to my base country or I can go to dubai for one day visit and then return to bahrain?

Also, i can extend my current stay for 2 weeks, but the form available on visa website asks for guarantor CPR, can some one please explain this?

Thank you so much for you time and reply in advance.

You just need to exit - destination on exit is immaterial.

Guarantor CPR is for sponsored visas.  If you have a sponsored visa, then this needs to be filled out by the organization that sponsored you.  If un-sponsored, no need to fill it unless immigration deem you as a risk and ask for it to be filled by a friend or relative.

Thank you , this helps.
