Tara has enough friends on the hospital staff to sell the story. Doctor was in on it. Tara really has become Gemma. It was maestro stuff.
Venus storyline was way more f'ed up than I expected.

As SwampYack said, the doctor is checking for a heartbeat to see if the "baby" was still alive. A common sense thing for a doctor to do...not a "in the know; trying to fool a biker" thing to do.
