The answer is: A. quickly decide on the main points she’d like to address and how to transition from one point to the next
The best she can do is: A) Quickly decide on the main points she'd like to address and how to transition from one point to the next.
In this way she will be organized and won't confuse or repeat any topics. As she is an experienced public speaker she won´t be that nervous and she probably has a determined procedure on making speeches. Although she was not prepared for this speech in particular she has been practicing medicine for several years so the medical procedure that needs to be explained is probably something familiar. In other words, she has the information and the experience to give the speech, she needs organize that information in an efficient way.
By excusing herself and hide, she will only evidence her lack of capability in that subject. Writing the speech on a napkin is not professional and lets remember that she doesn't have time as she is asked to speak at that moment. The notecards is a good idea but, again, she doesn't have the time to write or practice.
