How can a field change it's name, depending who is seeing the form?

Hi, 

I want a field change it's name according who is seeing the form, so let me explain.

I have a form and, Depending on who enters to the form, some fields will be displayed and hidden, But one part of the form appears to both equal people, but i need to change the name of "Hospitalizacion PR" to "Hospitalizacion" when Admin1 enters to the form, and if Admin2 enters to the form the field will appear like "Hospitalizacion UG", how can i change it?
