I've been on that service for over two weeks now (spending my vacations on a clinical summer), and it's not as hard as I thought it would be. It's main purpose is paliative, you only stabilize the patient and let him go or send him to internal medicine.

Funny stories happen from time to time, though:

A woman came to ER a few weeks ago with her baby, the doctor wasn't around but he told me that when that happens I check the patient, and if I don't know what to do it doesn't matter because he'd be back soon.

Anyway, the woman told me her baby hasn't stopped crying since yesterday and there was no appearant reason. So I checked the baby for probable sites of infection, ears, throat, lungs, etc. Interrogated the woman a bit more... heck I turned the baby upside down and he was perfectly ok.
So I remembered a doctor once said: "Babys only cry when they're in pain or hungry", so I asked the mother:

Me: "Have you fed your baby lately?"
Mother: "Not since yesterday, because he started crying and I thought he had something in his stomach"
I asked her to breastfeed him, and as soon as she did the baby stopped crying.

No comments.

Still, have a learned a lot in this two weeks. Not only medical information, I'm also learning to recognize fakers only wanting attention or drugs.
Weird place we live in.
