Math...again  page 2
Here i am once again. i do not understand the drip factor stuff. I have an order of Aminophylline 1gm in 500 cc d5w to infuse at 0.5mg/kg/hr for a pt weighing 154. The first question is what is... Read More

Dec 2, '07Quote from SarasotaRN2bThere's nothing wrong with reasoning through a problem.Butyou have to use the right formula! What's wrong with reasoning through a problem?
I just have a preference for formulas as I have an easier time remembering them and such.
AND, in case you are getting at what I think you are getting at...I view the "reasoning" of chosing the right formula for a problem as different from reasoning *your way through* a problem. 
Dec 2, '07Quote from Cosper123Yes, but if you don't have the right formula, it won't help much. I don't know what you think I'm getting at...but that was a comment made in general, not towards you. It's just something that I found that helps me put everything in the right position. Maybe it will help someone else.There's nothing wrong with reasoning through a problem.

Dec 3, '07If you're using dimensional analysis there is really only one formula to be concerned with:dose desired divided by dose on hand to give you the dose you want to giveYou only want to make sure you have the dose desired and/or dose on hand term in your calculation (if that is what is called for). Everything else in the formula is a conversion factor, including the drip factor of any IV tubing, and put into the resulting formula designed to give you an answer with the correct labels on the numerator and denominator of the final answer. How much easier can you get?
