There was a rotation in residency where I did epidural injections under fluoroscopy every Friday. On my first day, the resident who was doing them the block before me was explaining to me and another resident what to do.
Resident: "So you take the patient into the examining room...."
Me: "Examining room... got it..."
Resident: "Have them sign the consent form..."
Me: "Consent form... okay..."
Resident: "Then you go ahead and get an IV started...."
Me: "You're kidding."
Me: "Um, I don't know how to start an IV."
Other resident in room: "Me either."
Resident: "Well, you can give it a try."
Me: "Seriously, I've done it like, once. I could maybe draw blood if I had to, but there's no way I can start an IV."
Resident: "Actually, I don't really know how to do it either."
How many residents does it take to start an IV? Clearly more than 3.
I know it seems like residents should be able to start IVs, but there's really never any reason to do it when there's ancillary staff around. Nurses draw blood, insert Foleys, and start IVs. I just write, "Start IV." I'm really good at that part.
In fact, if I wanted to get good at IVs, it would have taken a lot of effort on my part. I would have had to show up early for surgeries or stalk nurses or something. So I didn't do that. And up until that day, it had never ever been a problem.
