"What do you carry with you on shift?"
This question has come up a few times, so I figured I'd put it down in one place:
Sharpie (industrial) for marking landmarks (#13; eg cric, LP, and paracentesis)
2 sheets of paper, folded in quarters for signout, notes, etc.
iPhone (not pictured, because it's taking the picture)
Trauma shears: most useful ED tool
mini-LED (like these)
retractable reel clip
stethoscope; still useful in a handful of situations, mostly wheezing, reiki, and leading into questions about smoking
head lamp (AA battery powered) for things like finger & scalp lacs
meconium aspirator & swivel adaptor for messy airways
extra guaiac cards & developer
3-way stop cocks -- poorly stocked in my ED, can come in handy (here, here, here, here, here, here)
