I am so intrigued as to what you do now..
I am trying to think of a time when i have had to have an answer to a question in a professional setting and have ever said this.
I can not recall, nursing is not exactly an environment that stimulates us to ponder questions. The doctor says is the patient alive and if i said that's a great question i might get fired hahaha!!!
I tend to be honest and if i dont know an answer i say i have no clue, let me google!! I am also, technically an unemployed bum at this point (but thank you medium for supporting this).
