Need abbreviation help

Before meals and at bedtime.

Q is "every", AC is "before meals", and HS is "bedtime"

It is more frequently written as AC & HS. This was just poor transcription or handwriting.

The part I can't figure out is the abbreviation pst . It looks like those are the letters comparing his "p" with other "p"s in the letter .

I'm not sure what pst could stand for and there is the possibility that the next two letter after the p are not st.

Anyone have any idea in the context of the sentence what it could be? (The patient was treated for prostate cancer by chemo and radiation therapy without any improvement).

"Q" is not an acceptable abbreviation any longer, per Joint Commission. We should write out "daily". Might as well get in the habit.

pst is probably made up by the MD - which is a bad habit for him/her! This is the very reason nurses can make mistakes - by trying to guess what the MD wanted. My practice is to call them to verify. Even at night. If they want to be cryptic they pay the price. But as a student, you will have to ask someone who works there probably.

pst is short for pssssttttt which means be very very quiet and only whisper :rofl:

I was gonna say pacific standard time... Or please send tell (old online gamer abbreviation)

If anyone goes crazy over abbreviations like me, you can pick up a book by Neil M Davis called: "Medical Abbreviations: 30,000"

I bought it thinking I would never use it, and wound up using it a lot. It makes my life so much easier.
