Will Low AP Bio Grade Mean Rescinded Acceptance?

Question: I recently was accepted to my top school for nursing. I even received a scholarship. However I recently found out that I failed my AP Bio midterm. I talked to my teacher and she told me i was still passing this semester. I talked to my guidance counselor and she said they don't receive our actual midterm test grades, they just receive mid year GPA and grades in subjects. This means they see that I passed AP bio and they see whatever average I have in it.

My overall average has increased since Junior year. I'm just worried that if I have a lower grade in AP Bio, for example a C or a D, would that result in me getting declined? My other grades are high, and at the time of acceptance they did not know I was challenging myself with AP Bio.
