I'm in my senior year of my BScN program and so far we've had to do many papers. Some are care plan-related, some are theory to practice related, some are community/primary health care related, some are philosophy-oriented, some are pathophysiology/micro related, and lots of self evaluations and peer evaluations, as well as reflective clinical journals. I've done so much reflection that I feel like I'm turning into a mirror!!
I would highly recommend taking an entry-level writing or university English course. I wonder sometimes by the quality of some of the charting I see by various staff members at various clinicals (not just RNs but other disciplines) if they even have a solid grasp of the English language! I am always reminded that once something goes into the chart, it becomes a legal document (care plan, progress notes, flow sheets etc.). Plus, good spelling and grammar, to me, indicates professionalism, and as an RN you might not necessarily be working in a "hospital" environment, you might be working in the community and writing proposals, doing research or giving presentations.
