I don't think I am allowed to give away the answers here. There is a formula for the drug computation and for u to answer it correctly u should understand the question.

I need help with drug calculation

Do you mean: Here is my 15 dosage problems, can someone do my homework for me?

You need to do the problems and show us how you got your answers, then we will guide you on how to get the correct answers. Doing them for you will not help you on your dosage exams.

Remember first steps convert the dosage to one unit either mg or mcg..

next you divide the ordered by what you have on hand and then multiply by the ml

hope this helps with some of them

Uh, I just did almost all of these in my head. This math is not complicated. OP, you need to do the work and show us where you are having trouble.

Draziga, use this formula:

Want/Have*Vehicle

So, you have an order of 50mg and what's availabe is 100mg/mL (PER mL). Put that into the formula:

50/100*1 = 0.5mL

Now, use this formula for all of your problems. :)

When you C&P 15 questions with a generic "I need help," it seems that you might not know the principles for drug calculations. Have you attempted to figure it out yourself? If so, maybe post step-by-step the process that you used so we can see where you went wrong. If you haven't tried it yourself, you need to. Cheating in nursing school *may* help you get a good grade (assuming you're not caught), but it will not help your future nursing practice. And it is cheating to pass someone else's work as your own. You cannot unleash yourself onto the public without knowing how to do this stuff. Side note, years back in this basic chem lab I worked at a station adjacent to a pre-med student. One day he sheepishly asked me, "Can I copy from you?" I said "Absolutely not. You want to be a doctor, you have to know how to do this stuff." ;) Same principle applies here.

And if you are confused about drug calculations overall and can't even figure out where to start, you should talk to your instructor. I think it would help you more overall to have someone physically sitting with you and reviewing the material.

Totally at random:

9. Physician order: furosemide (Lasix) 0.04g IV. The label reads: furosemide 10 mg / mL. How many mL will you give?

Step 1: Convert the physician's order into milligrams.

Step 2: Set up a ratio equation... If one milliliter has ten milligrams of Lasix, how many milliliters have the amount determined in step 1?

Step 3: Algebraically solve for the unknown quantity in your equation.

+++++++++

I gotta point out that these are about the simplest questions one could find.

I've a devious notion to provide the answers to all the posted questions...

but with the caveat that 25% of them will intentionally be WRONG... Take the lazy way through and get a C or check all of my work to figure out where I'm messing with you and probably get an A.

Seriously, there aren't any short-cuts to this stuff. Regardless of the obvious ethical issues with submitting someone else's work as your own (even in math, it's still plagiarism...), you're never going to learn it by inspection... you'll only get it by *doing* the hard work yourself.

You got to walk it by yourself
