Getting relevant experience before graduation

Hi all:

I am applying to accelerated BSN programs and will likely start one in summer '14 (if not Jan '14). Having read this site, I get a feeling that getting a job as a new grad is challenging at best, so I am thinking of trying to get relevant experience prior to graduation to help the job hunt after.

I understand that if I am enrolled in a BSN program I should be able work in a CNA/Technician type of role, which I want to try to do. My question is whether this experience will then prevent me from appying to new grad programs?

Also, I have been volunteering at my local hospital for close to 4 years now (which made me decide to switch career to nursing, actually) doing hand, foot massages and Reiki for patients. Do you think this experience would mean anything in future job search?

Thank you!
