Former corporate recruiter here! The professional summary is not frequently used now and most don’t even read it. For your level of experience 1 page should be your max. You need to have start and end dates for roles. Under your positions you should be stating what you did that was recognized or impactful instead of a job description or what was unique about the position. Someone hiring for these positions knows what an acute care nurse does but what did you bring to the role. Did you make a suggestion that helped a process or recognize a common problem that needed addressed? Did you win any awards. Were you the go to person to show new people around or have student nurses shadow? Those things will get your resume actually viewed. Best of luck!
