I remember way back when doing OE on the Triple, salty check airman warned me about medical diverts to small obscure stations in the frozen north. Can you taxi once you land? Can they even get the passenger off? Will you be able to takeoff? If not, are there facilities for ALL your passengers? What is the temp down there? Remember the other 300 pax when considering the needs of the 1 that needs medical attention. The real emergency might start once you've landed....Always stuck with me.
