drug compuatation specially in i.v

[darren_callcareer18]

hello to all of the nurses here..

I am a nursing student and I have a question again. I am really confuse about the drug computation(actually I have the idea on how to compute that thing like total volume/no. of hours* drop factor/ 60 and D/S*Q) But when it comes to my exam I noticed that there is something has been incorporate in my i.v sometimes its in gram and ml., and is there any considerations in computing the dosage for pedia or kids? The question goes like this a 9 years old came to the e.r and after the doctor check for him he ordered ketorolac 250 mg tiv, the stock for adult dose is 500 mg/ml how many ml should I administer? ( That's the question as far as I remember...)

Thanks a lot you all been a great help.

a useful site for drug computation would be a great help for my study. Oh LAST THING how could I convert ml/hr to gtts/min.

Equivalents:

1 ml (cc) = 15 gtts = 15 m

4 ml (cc) = 1 dram

5 ml (cc) = 1 tsp

30 ml (cc) = 6 tsp = 2 tbsp = 8 dr = 1 oz

500 ml (cc) = 16 oz = 1 pt

1000 ml (cc) = 32 oz = 1 qt = 1 liter

1 mg = 1000 mcg

60 mg = 1 grain

1000 mg = 1 Gram = 15 grains

1 kg = 1000 Grams

1 kg = 2.2 lbs

I love clinical calcs. Memorize the above and it will help you much - if you need write them quick on the back of your test before the test starts (from memory!!) so you do not get nervous and block out the info.

Look up dimentional analysis - If found this the easiest way to learn and honestly I think it is fun to compute. (sick I know! )

Oh LAST THING how could I convert ml/hr to gtts/min.

Find out how many mls you need to administer, and then also how many hours you have to administer that total amount. For example:

You have 1000 ml of Kool-Aid, to administer over 10 hours. The drip factor for the tubing is 15 gtt/ml.

This is how you'd set up the problem. First, you need to find out how many ml/hr you will have.

1000 ml = 100 ml/hr

10 hrs

You would then take that amt of ml/hr, multiply that by the drip factor for the tubing, and divide that amount by the # of minutes (in this case, 60 min/hr. Be careful, though, because some problems will already give you the amount of minutes, in which case you can skip the first step as shown above).

100 ml/hr X 15 gtt/ml The answer is 25 gtt/min.

60 min/hr

Hope that helps!
