Pharmacy calculations for Technicians - Milliequivalents

Short video explaining milliequivalents (mEq) and how to convert from mg to mEq. It will help if you have viewed the introduction video before viewing this.

Oops, I wrote mol when I should have written mmol when I was talking about Ca++.

I have a final exam next week in this, and I have been near tears trying to get it straight in my head...I think I am finally there.thanks!

Thank you so much for taking the time to make this, you've made prepping for the exam a breeze!

Thank you so very much Dr Wojcik your tips and way of looking at certain problems is very insightful. I will be starting pharm tech school in a while and i really enjoyed your videos so far. you would be a really bad ass chem professor.
thank you very much again.

Thank you so much for making these videos for pharmacy technicians your helping me understand it way more on the math an I'm about to take my nationals test really soon an i'm feel a lot better now because before i was little more confused but now i feel so much better thank you.

Pharmacy tech here. Had an out-of-stock situation today with a med commonly measured in mEq. Patient came to pick it up along with its paired diuretic. At the counter, during rush hour, the following ensued: "Don't have my potassium?? That's alright, I'll just grab it otc; how many mg did the doctor write it for?" Apparently it would have taken me the same amount of time to do the math as it would to call another store! I smoothly dodged his question by choosing the latter. Thanks, though, Doc!

Nice ! Clear, Quick just what I needed to review

[stevendusseau]

Very helpful explanation. I never used mg/mmol (only used g/mol) in chemistry so I was confused at first about it, but it makes more sense now that you explained it.

Thanks Uploading video Sir, I was struck in millimoles your video helped me come up. Do not have words to express your kind gesture.

How did you get 746mg in the beginning of the equation? The only way I figured out how you got 746mg was after adding 39.1 + 35.5 = 74.6 x 10 = 746, but where do you get the 10 to times the 74.6? thank you

hi Dr.Brad, I really find it difficult when it comes to computing meqs. I keep on researching and watching videos on youtube just to fully understand but I really can't cope with it. I am now reviewing for boards and I really wanna know about this one. no matter how I try, I am still getting the wrong answer this is the formula that they gave us during review days meq=mg/MW x factor. some articles says valence instead factor. what was the simplest formula in getting meqs for solving board problems? thanks for helping!

[trainlatissimus]

thanks for the video brad. one quick question. how much Ca2+ (in mEq) and Cl- (in mEq) are there in 20mEq of CaCl2? thanks

[JennyNguyen]

thank u. ur vid is so much more helpful than my dry, boring textbook !!!!

[tonderaitumbare]

thank you brad for the good video. my question is how will l prepare a 50mq Ca ion solution given a calcium carbonate compound

[kelignz]

For that last step in which you solved for mEq I found a formula, just in case anyone wanted to use it. mEq=(substance in mg x valence #)/atomic weight

[dimkacracker]

so say we had potassium sulfide, would it be 2 meq/1 mmol? Do we always choose the highest charge in the compound and ignore the lowest? Since sulfur is -2 while potassium is +1.

dr brad thank you for the good work 
my question is about m mol and m osmol what is the difference, i revise the issue in comprehensive pharmacy review but i can`t apply it to cholesterol conversion from m mol to mg/dl something is missing!!!

[AliHassan-dfre]

thank you Dr.brad
i have question
what is the weight of CaCl2.2H2o need to prepare a liter of solution containing
1-9mEq Ca/L
2-7mEq Cl/L

[rajivdangol]

Very Nice video., and i was curious to know about conversion of mOsm.?

[anisnadhira]

Thanks doctor for helping me out with the calculations.
