Question 22930: Can someone help me with these problems I am so confused.
1. How many milligrams of zephirin chlorde are needed to prepare 3 L of 1:30,000 solution.
2. How many milliliers of a drug would be needed to provide a 10,000 mcg dose from a vial containing 0.1 g/10 ml?
3. An order is received to administer 5 mEq of potassium acetate per hour. The bag of I.V. fluid contains 30 mEq per liter. How many drops per minute would be needed to provide the prescribed dose using a set that delivers 15 gtts/ml?

You can put this solution on YOUR website! I don't know why you haven't received a response on this
query, but I for one do not understand your unit references.
What is an "mcg dose..." and what is "mEq" and whate is "gtts/ml"?
Are these all related? and how?
Cheers,
Stan H.

You can put this solution on YOUR website! There should be no need to explain "mcg", to tutors!! But apparently some tutors do not know that this means "micrograms" or 1/1,000,000 of a gram. Amazingly, tutors in algebra.com can actually score points by exposing their ignorance and stating that THEY DO NOT KNOW HOW TO SOLVE THE PROBLEM!! It's a weakness that probably has no cure.
I must disagree with the previously posted comment by the tutor who said the reason your question was not answered was because it was not stated clearly! Your question was clear enough. It's just a hard problem that MOST TUTORS HAVE NO CLUE AS TO HOW TO SOLVE--or perhaps you should post only one question at a time, instead of posting THREE blockbusters in one problem!!
As to a solution, I didn't solve it because I only have about 10% confidence that I could get it right!
I'm very sorry, but now there are TWO tutors who have scored a point on this problem without giving you a solution. Perhaps you should re-post it. We do have some tutors who can do this one--maybe Kenny or Longjonsilver???

You can put this solution on YOUR website! i have to agree with the previous answer...
for me personally, there are too many units used here that i am unfamiliar with (i am English and we strictly teach in metric these days). I have no idea what mEq or gtts/ml are.
As for answering part 1, i am 20 years rusty on chemical solution calculations, so i would not be 100% confident in answering theis question either.
