Would graduate school rescind my addmittance over one poor grade?

I’m a college senior getting ready to graduate with two science degrees and I’ve been accepted to a handful of graduate programs in Public Health for next year. My overall GPA sits around a 3.2 - lots of 3.0s and 3.5s with some 4.0s in EPI and Health classes that I actually enjoy. I’m working as many hours a week I’m allowed to during school - on top of being an RA (since that isn’t hourly) - etc - so I do what I can.

This semester I’m looking at two 3.5s, one 3.0, and there’s one class I’ll likely slide by with a 1.5 in (which I’m allowed to have and still graduate, as my science major cumulative will be very much above a 2.0, which is the rule).

If I had more time this semester, I know I could’ve at least 3.0ed it if not higher. Do I e-mail the schools before sending a transcript and explain this then ask if they’d prefer me to re-take the course this summer (as it is available and I’ll be in the area)? Or do I simply send this final transcript? Do you think they would revoke my acceptance over one clearly poor grade - even though it did NOT affect me being awarded my degrees and my GPA remains above a 3.0?

(Note that my cumulative GPA drops very little as I have taken just over 150 credits, so it only falls to around a 3.14 or something.)
