An intern is not qualified to practice medicine when he is dead, and besides, he is not in the hospital. Another thing to say is that if you know that it is a small-scale drug, you can be detained or sentenced for illegally practicing medicine without a license. If the hospital recognizes that you are here for medical examination, the hospital will temporarily arrange the hotel to practice medicine, with evidence or notice. The problem is not big. You can be detained and fined at most. The rest is all about the hospital.
