Titration Math


0Feb 1, '08 by 4rom2bRNMy instructor gave me this sheet that states what it is. I hope this helps.
The Nursing Math Titration is for you the nurse to calculate.
Some drugs given IV are potent and may affect the patient quickly. Drugs are given by titrating the dosage. To ensure that you the nurse give the proper dosage of admininstration you must know how to calculate, an IV infusion pump is used. These machines are calibrated to deliver a specific amount in ml/hr.
You the nurse is responsible for solving MCG/KG/MIN or HR, MCG/MIN or HOUR and INFUSION RATE.
You will have an exam on Tuesday, Feb. 5, 2008 promptly at 815am. Anyone showing up later than that will not be able to take the exam. And will receive a grade of Zero.
This is the only thing she gave us. One of my classmates asked her if she can stay after class to show us. She replied with that's not something that she does. We went to the nursing tutor. After the second day with the tutor. The tutor told us that our instructor requested that she does not teach us titration. That we needed to dig for ourselves.
I have been doing research here and on the internet. I really don't get it.
I really appreciate any assistance. If you read my previous thread, I cannot afford to fail any exam. I am suppose to graduate in less than 14 weeks.
Please HELP! 
2Feb 1, '08 by Daytonitegot it. two drugs that come to mind that they do this with all the time in the icu are dopamine and dobutamine. they are ordered given by mg/kg/min, but there are others as well. these drug problems are best done by dimensional analysis because they get quite complicated. you often have to convert the patient's weight from pounds to kilograms and the drug from grams or milligrams to micrograms. some of these problems will also ask you to calculate safe ranges based on a patient's weightmeaning you'll have to work the same problem twice using different numbers to get two answers: the highest and lowest safest dose you can give to the patient. these titration problems never end up with the same labels on the numbers that they started out with which is what makes them such a pain in the butt to work, so you have to know your various conversion factors. you also have to understand that certain relationships must remain together (which is why dimensional analysis works much better to do these problems).
i have solved a number of these problems for students on the dosage calculations thread (http://allnurses.com/forums/f205/dos...ons88867.html) you should take a look at the tutorials that are listed under the heading of "medication calculation help and practice problems you can work" on the nursing math thread. i'm giving you the link to it below. i organized that listing so the tutorials were the first ones on the list. these are all on post #3 of this thread:
 http://allnurses.com/forums/f50/nurs...ad264395.html  the nursing math thread (in the general nursing student discussion forum)
if you can find problems to work or you just make up problems and need to see how they are worked, post them, i will work them out for you and show you how they are done by dimensional analysis because that is the only way i know how to do them. in several of the ones i worked on the dosage calculations thread, i believe i gave some direction on how dimensional analysis was used as well. i think that dimensional analysis is the only way to keep all the calculations organized in solving these kinds of problems.
