Most people have already mentioned before that it's not just GRE scores but the whole application. I say retake it if you feel you need to. You qualify above the minimum scores required anyway. You have a great GPA with years as a Respiratory Therapist. I'm actually quite worried haha. I have similar GPA but higher GRE scores in the 80th percentile. I am still only 21 so I don't have crazy work experience. I think you are fine though. Hope to meet you during an interview.
