Elliot: Carla, the orderly lost my chart for Mr. Tyler in 406. Would we have his dosages in here somewhere?
Carla: You were going to put him on penicillin, but he was allergic, so you put him on a gram of vancomycin.
Elliot: Thank you.
Janitor: You should you put some of that crazy-nurse memory to use on our missing dude.
Carla: Well, he was an older guy and he was on an IV, so he couldn't have gotten very far. He was jittery and he had this weird circle tan line on his arm. It was the nicotine patch. He was trying to quit smoking.
