You took a math coarse.

Before you test again, find somewhere (or some source) that teaches you medication administration and calculation, also features reading med labels, and conversions. Going from mg to g decimal goes to the left. G to kg decimal goes to the right. 5 mls in a teaspoon, 3 teaspoons in a tablespoon therefore 15 mls in a tablespoon. In math you learn 3a = 24, a = 8. On a med test the baby has to get 24 ml of med in three divided doses, how much do you give at 0900 and when is the next dose due?

Many students fail because they don't understand WHY and WHAT they are calculating. U have to understand your conversions and formulas. If you don't know which formula to use for any given calculation, then you will fail.

As poster says above, you may understand maths but u need to learn NURSING maths. If you can't covert say from mcg to mg or vice versa, then you need someone to teach you all this.

Also if you calcluate something, look at it and ask: DOES THIS LOOK RIGHT? If it doesn't look right or is too big, you know u have done something wrong. Have a look at the drugs being calculated in an online drug book, and see what dosages they are given in. For instance, with the drug Thyroxine, you would never give this in mg, it is always given in mcg. But most drugs are pretty standard when ordered. However you still need to know how to calculate because you may get an odd drug in an odd dose. Always double check calculations if unsure or follow your facilities'/countries policy re this.

If you want help, I have a bit of time before I start a new job, I would be more than happy to help you.

You also need to sit and write down what you DON'T understand as well. What do you have trouble with? Try and identify ur weak spots.

BTW virgo, I was THE BIGGEST DUNCE at maths, and if I can get it and pass medication calculations, you can too!

There's a little book I taught myself from. It's called Nursing Calculations by JD Gatford and Ron E Anderson. Very easy to follow with good examples and all the answers are in the back. It goes through all the basic calculations, common medications and how they are calculated, syringes used, all oral, IV and other meds, and also tells how to calcluate for adults and kids.

Also don't feel like u have to struggle alone. If you need help again, come on here and ask - don't just sit in a funk of despair feeling like ur an idiot (like I used to tell myself!), thinking nobody cares. There is always someone happy to help you :)

Dosage Calculations by Pikar

There is not a more clear book out there. I've looked at a lot of them and this one really is the best.

Meghan91: no paper and no calculator? are they nuts? we get a calculator and a white board for the NCLEX for goodness sake!

Hello everyone. Long story short. I took the LPN exam in Dec 2011. I failed by 5 points. I then decided that I would take a refresher course in basic math. I did take the course, and I had a wonderful teacher. I learned a lot, and was so proud of myself for doing well. I passed the math class and the final. Fast forward. to May 20th, I re tested for the math portion. This was the only part of the test that I failed. Well, I failed again by 5 points. I feel like all my hard work is out the door. I am going to continue to purse my goal, but I am feeling let down. Any suggestions? Thanks.
