“Uh-oh.” It does not even matter what the context happens to be, these syllables should never exit your lips. Ever. You can (think) it but never, ever say it. No one needs an insecure pansy in a crisis. If you don’t know something, by all means say so, but do it with confidence.
“That’s interesting…” when doing an exam. For instance, when listening to someone’s heart saying, “You have a new murmur,” is much nicer than, “Well, that’s interesting…” Vague comments are very scary in a clinical setting.
“That feels nice.” when palpating anything. I watched an OB attending doing a bimanual exam (two fingers of one hand in the vagina and the other hand pressing on the abdomen) on a woman with post menopausal bleeding. He sort of grunted, looked up at the ceiling, then said, “Oh, yeah. That feels real nice.” It didn’t help that he was wearing long scruffy hair, pointy cowboy boots, ragged out blue jeans, and a T-shirt with rolled sleeves…. I am very careful now what I say during sensitive, embarrassing exams. First and foremost to preserve dignity. Second, so as not to end up as an amusing anecdote on someone’s blog post.
“She/he only has X amount of time before they die.” The powers that be always have a way of showing that YOU are not the person in charge here.
