Medical Staff No-No Phrases

While seeing my dental hygienist today, I joked with her how certain phrases should not be used by medical staff. The #1 biggest no-no (IMO) is "Oops."

She has been at her job for over 30 years. Some of it is mindless routine work, for her, anyway. She told me how one day as she had sharp metal tools inside a man's mouth, she muttered, "Oh, darn!" His panicked reaction made her quickly respond, "Did I say that out loud? Oh, no. You're fine. It was nothing." What caused her comment was the fact that she'd just remembered something she'd forgotten to add on her grocery list that morning.
