New graduate resume help

Hi everyone,
I was wondering if anyone has any suggestions on how to summarize your clinical experience on the resume. So far I just listed where I had my clinical rotations as follows...

XXX Hospital, 2013, city, state
Family-Centered Maternity Nursing

XXX Hospital, 2012-2013, city, state
Child Health Nursing
Psychiatric Nursing
Medical-Surgical

XXX Hospital, 2012-2013, city, state
Medical-Surgical (Nursing Care of Adults)

I know some people put the amount of hours but I don't have that information. However, I'm wondering if I should create a few bullet points under each rotation summarizing the responsibilities or what I did...any suggestions?

All help is appreciated....
If you have blank space then put in bullets but if your resume is full then just leave it
