I don't understand is the use of Latin to describe how many times a day a nurse must administer pills.

I am sure doctors and nurses have to LEARN that t.i.d means Ter in Die (three times in a day), likewise for b.i.d. and q.i.d. These are not terms people generally know. So why are they bothering to teach them the abbreviations instead of just saying "give the patient a dose three times in a day" which is no more subject to interpretation than t.i.d. I am sure there are much more important things that they should be concentrating on instead of highbrow vernacular for common phrases.

And how is the word NOW not as clear as STAT?
