Ok. So I'll start by saying that when I hear the office or a nurse say "orientate", it is like fingernails on a chalkboard. Its orient, not orientate.
Another one is O2 "stat". Its O2 sat, as in saturation.
Its trach, not "trache".
Or parents who tell me their kid has a trachea...I sure hope so! I want to tell them their kid isn't special for that and that we all have a trachea.
Parents that tell their kid I'll give them a shot if they don't behave. I'm not around to cause pain or scare a child.
And parents that speak Walmart! When they tell me they want to "axe me" I fear for my life or my job and then they just ask me a question.
Incorrect spelling of meds. It can lead to a med error. The med name is on the container. It can be looked up online if needed. I can't stand hearing "Phenergren", its phenergan.
Seeing/hearing yankauer spelled/said incorrectly. Passy-Muir is another.
Formula doesn't always have milk in it. Some patients are allergic to milk/dairy. Calling it milk and saying you don't want your kid to drink milk because its too much milk just sounds silly.
I'll think of more. Any others?
