Getting ready to take my semester II med calc test. I'm seeing some stuff on the practice test that I don't quite know what to do with. First, what is the conversion of meq to mL or whatever it's best converted to; and what in the world is an meg? I've never seen an meg and it's not in any of my resources.
Here's a question and maybe a doseage queen/king can tell me how to set it up:
NS with ammonium chloride is infusing at a rate of 131 mL/hr. The IV solution was prepared by adding 200 mEq of ammonium chloride to NS. The final solution contained a total volume of 1,000 mL. How many mEq are infusing per hour?
As always, thanks!

this is a simple formula i learned to determine how many cc's/tabs to give-take the dose ordered, divide it by the amount of med on hand then multiply by the volume. example- dr ordered 800 mg Acme ABT q 12 h. available to the nurse is Acme ABT 500mg in 5cc. how many cc's do you give?
______ X 5 cc= 8 cc
1. Dose (800 mg)
2. Divided by med on hand (500 mg)
3. Multiplied by the volume (5 cc)
= amount to give
in order to find out the answer to your problem, RNkittykat, you change the above formula around a bit. say the dr ordered 8 cc Acme ABT. available to you is Acme ABT 500mg/5cc. how many mg are ordered?
____ X 500 mg= 800 mg
1. take the volume ordered (8 cc)
2. divide it by the volume of the med on hand (5 cc)
3. multiply by the amount of the med on hand
= amount of mg ordered (800 mg)
once i learned these formulas nursing math became so easy. just remember to practice. best wishes on your test!
