There should be minimal bullet points. Anyone reading your resume knows what a beginner-level staff nurse does, so there is no need to embellish your resume with a lot of details. That only makes it look as if you are trying to "puff yourself up."
Simply say that you were a staff nurse, give the dates, and a very brief description of the types of patients you cared for. After listing the place, your job title, and dates of employment ... the description section should be no more than 3 or 4 lines long (at most.) As you get more experience, that section should include a basic statement of the type of patient cared for along with any special responsibilities such as Charge Nurse or Preceptor. In addition, you would list any committes you participated in regularly or special projects that you worked on.
If the hiring manager wants details -- that's what an interview is for. You might want to take a detailed skills list and/or copies of your performance evaluation with you to any interviews.
Routine school activities should not be included in a professional resume. Only include those things that are "special" in some way -- things that are not done by most students. For example, scholarships
, awards, special programs, etc. You might include a senior preceptorship or special project early in your career and/or it is relevant to the job for which you are applying.
