Me: Well, ma'am, I can guarantee you this is a pretty routine order for the prevention of blood clots in the hospital. You can look at the written order here if you like.
Patient: Naw. That don't go in a shot. I ain't takin' that. You nurses here are dangerous.
Me: Alright, well, I can't make you take it. I'm pretty sure skipping dialysis for three weeks didn't kill you, a DVT probably won't either. Also, I'm pretty sure you aren't supposed to chew tobacco in here.
...and end scene.
