It's controversial to include clinical rotations on your resume as all new nurses are expected to have gone through clinical rotations. Many members have posted that hiring managers have commented about their resume that includes a large section listing/detailing clinical rotations stating that so what, everyone else does clinicals as it is required to graduate from nursing school
What is often suggested is if you had a unique experience, practicum, or rotation to include that in your resume. Such as, if you had a rotation where you were able to request a particular unit that not everyone else experienced that would be something to highlight (like a Burn or Trauma ICU, which would be an experience that not many other student nurses would have opportunity for.)
Or if one of your rotations were at the facility to which you are applying (such as you are applying for a new grad pediatrics rotation at ABC Hospital. You had an awesome clinical rotation, the nurses likely remember you and your clinical instructor wrote a glowing recommendation. You can also state this information in your introductory cover letter. Such as "I was motivated to apply for this new graduate pediatric nursing position after having an inspiring experience while completing my clinical rotation in pediatrics and pediatric intensive care at ABC Hospital from April through June 2012. I had the opportunity to assist the nursing staff in direct patient care and assessment, medication administration and participate in family care planning meetings. Enclosed is a recommendation from my clinical instructor from my pediatric rotation."
