If you truly have no clue, then I think the place to start is to figure out what you want and what you have. I think people get WAY too hung up on simply plugging numbers into a formula without understanding, so I think you should look at the big picture as a first step, always (it's a great way to have a general double-check of your math, too).

What do you want to administer to the patient - how many milligrams?

And how much medication (milligrams) do you have in that vial, total?

Will you use all of it, some of it, or more than one vial?

[btf4]

1.5 ml? because 2ml is 8mg so 1.5ml is 6mg?

[btf4]

i need to administer 6mg

the total mg in the vial is 20 mg

i will use some of it

Yes.

Now you see the big picture and you do have the right answer.

Can you put that into a formula so you could do this same basic problem with a different order and a different vial/concentration?

for the second portion of the problem is it, 17drops per minute as the answer?

x gtt= minute * 50ml/30min * 10gtt/ml * = 17gtt/min
