ung = this is the latin abbreviation of ungentum which means ointment

oint = this is the abbreviation of the english word ointment

So....both are correct - just different (like the word boot - meaning a kind of shoe in US or the trunk of a car in the UK)

The differences in your weight issues relates to an antiquated system between the avoirdupois weight (which is used in shipping) but we apothecary weights in compounding & dispensing.

In the apothecary system...1 oz = 31.1 gm
In the avoir system ..... 1oz = 28.35 gm

gtt = a drop or drops (derived from Gutta or Guttae)
gtts = an english multiple of gtt

gt - who knows??? If it is in relation to an eye or ear drop or other mecation dispensed by drops - use your best judgement.

I agree with oint/ung and gtt/gtts... but I really don't know what gt is.. and i've been working in a pharmacy for 2 years and got certified as well. just worry about recognizing gtt, the ptcb will not trick you on whether gtt means drop or dropS.

took the ptcb, ointment wasn't on there, drops/drop doesn't matter.

oz is 30 g

grain is 60, my review book said 65, for some reason.

they like to ask u ear/eye abbreviation, right/left. I just remember it by drawing two little dots in the O and think of it as eyes. 🙂

1oz is for 28.35 g for avoirdupois - you use this for pre-packaged meds.

1oz is 31.1 g for apothecaries' - you use this when you have prescription medications.

grain is approximately 60~65.

Just finished PHT 031 (Pharmacy Calculations.) Book says that actual 28.4 g/oz but is almost always rounded to 30 for compounding because of ease of use. I'm not sure which PTCB will say is correct. I'd use 30 personnally. My instructor is RN instructor as well and says use 30.

definitely ung, definitely gtt, gtts

GT, really nice sports car.😎

1oz is for 29.35 g for avoirdupois - you use this for pre-packaged meds.

1oz is 31.1 g for apothecaries' - you use this when you have prescription medications.

grain is approximately 60~65.

If u wanna get those questions right on the ptcb exam u will use 60mg for a grain and 30g for an OZ.

if u wanna get smart and use something else, go ahead.

I'm not trying to be smart. I'm just telling you what my Pharmaceutical Calculations teacher told us. Our textbook says 65, but he told us it can either be 60 or 65 depending on what you're compounding/filling.

While it may have been an intentional sarcastic pun, I'm hoping he meant the difference between book smarts (I know what pi is 8 decimal places out) versus being right (3.14 on any given test.)

I just looked in my 2006 Generic Brand Reference book, and it says:

gt = a drop
gtt = drops
