OB/Gyn Math

This is the exact same math that you need to use for your medication calculations, just simple math/algebra will work. Nothing more is needed, not even a calculator if you do not have one with you.

Take each problem and go thru it one step at a time. What is 7% of that weight that you listed? Subtract that from the number, and then convert that to pounds and ounces.

well, first of all, stop freaking out. nurses don't freak out. they use their brains and any resources they can get their hands on to find answers. do you have a nursing drug reference or a medical dictionary? check the appendices in those and in your nursing textbooks for a table of weight or volume equivalents. you'd be surprised what the appendixes of some of your books have. if they don't have conversion tables in them there is a website called convert me.com where you can get these: http://www.convert-me.com/en/

1 kg = 2.2 pounds

1 kg = 1000 grams

1 kg = 32 ounces (actually 32.15 ounces if you're a purist)

1 ounce = approx 30 gram (actually 31.1 grams if you're a purist)

1 ounce = 30 ml (or cc's)

1 liter = 1000 ml

1 pound = 454 grams (actually 453.59 grams if you're a purist)

1 pound = 15 ounces (14.583 ounces if you're a purist)

with those conversion factors you should be able to convert a baby's weight and their feeding formulas.

baby lost 7% of birth weight of 3648 gm. how much do they now weigh in gr, kg, lbs. this problem is asking "what is 7% of 3648 grams. give your answer in grams, kg and pounds."

whenever you see a word problem asking for a percentage of something you are looking at a multiplication problem. expressing the answer in grams, kg or pounds involves applying a conversion factor to the final answer. all of this can be easily accomplished using dimensional analysis (factor label method), like this:
