Med Dose Calc. Problems

[lizzyberry]

Hi I just started the nursing program and they told us we have to do med dose problems and if we do not pass them we wont pass the class. I can remember how to do the med dose calc problems sort of but its been two year since Ive taken Med dose. My Question: Does anyone know the metric chart I forgot I know it goes something like this:

1gr=1000mg=?grain

1mg=1000mcg=?grain

1 ml=?

2 tabls=?oz

Drams ?

Drains?

Does anyone know these or where I can find them. Because we need to really know these by heart for med dose right?

http://kcsun3.tripod.com/id73.htm perhaps this will help.....didnt check it out extensively.....also drams and grains are NOT metric measures, but apothocary (sp) measures, rarely used...good luck

check the appendices of your nursing textbooks and your nursing drug handbook, if you have one. if you have a medical dictionary (i.e., tabers) there are measurement tables in the appendix and some information in the pages of the dictionary itself about the various measurements. grams and liters are part of the metric system. ounces, grains and drams are part of the apothecary and avoirdupois systems.

watch your abbreviations and make sure you are getting them correct, particularly g, gr and gm!

1 gram(g)= 1000 milligrams(mg)

15 grains(gr) = 1 gram(g)

1 grain(gr) = 60 or 65 milligrams(mg)

1 milligram(mg)= 1000 micrograms(mcg)

1 milliliter(ml) = 16 minims, or drops(gtts)

1 teaspoon(tsp) = 5 milliliters(ml), or 5 cc's

1 tablespoon (tbs) = 15 milliliters (ml)

2 tablespoons(tbs) = 1 ounce (8 drams), or 30 milliliters(ml), or 30 cc's

1 dram(dr) = 3.697 millilters(ml), or round off to 4 ml, or 4 cc's

don't know what you mean by drains ?????

i would highly recommend that you snatch a plastic medicine cup and take a good look at the markings on it. it has ounces/drams, tsp/tbs, and cc's/ml's markings on its three sides. you can also use these websites to create your own conversion tables:

You should also know that Google has a great "natural language" unit converter.

For example, type in "1 grain in grams" or "1 ml in tbsp"

here is a couple of rhymes that helps me everytime! it doesn't include all conversions, but some main ones. if you can remember these, simple math can be used for larger or smaller doses.

30 monkeys laughed at 1 o ld zebra

8 dozen roses, 2 turkeys, 6 tums.

so...

30 mls = 1 oz = 8 dr (drams) = 2 tbs (tablespoons) = 6 tsp (teaspoons).

they are all equivalents of each other. so, if your questions says 60mls, you know that you need to double the number of all the other figures, etc.
