I disagree about the girl’s need to know. She perceptive enough to know that something is seriously wrong. Leaving her in suspense would be far worse than telling her, especially when she knows that everyone around her knows what’s going on.
Besides, even if the cath results showed something else, she’s still a teenager with serious cardiomegaly and tricuspid regurgitation, so she has something serious going on, whether it’s PPH or not. (It’s too late and I’m too tired to come up with what else it could be.)
Of course, it would be completely inappropriate for Abby to tell her, but Susan seems to be awfully passive on the issue. I would encourage the parents to let me tell her what’s going on and involve her in the decision-making process. If they refused, I think the MD could make a case for overriding the parents and telling her anyway.
As for the rest, Corday is really hot, the new med student is really hot (I clearly have a think for British accents, or maybe my wife has just been out of town too long), Chen was a real bitch (what, did she think Pratt was off ring-shopping?), the schlong-waving match between the new resident (“Coop”) and Romano was great (I’ve had colleagues dumb enough to pick fights with attendings), and the Abby Has A Bad Day episode has been done before.
