Very good. Now try #3. I use Doc(what is ordered) over stock ( what you have on hand) formula.So you will divide 5 by 2 to get the answer. Let's see what you come up with.

so number 6 and 7 are correct? and I don't get why you would divide 5mg/2mg/ml. Is it because you are technically cancelling out the mg, leaving ml?

oops.double post.

You need 5mg.You have 2mg/ml. How many mls will you need to give to come up with 5mg? 5 divided by 2 is 2.5.You would give 2.5 mls.

DosageHelp.com - Helping Nursing Students Learn Dosage Calculations is a great site. for dimensional analysis try http://www.davesems.com/files/drug_d...lculations.pdf

Oh i understand now. For number 2 this is how I would solve it.

10mg/kg/day , since its divided every 12 hours I would do 10/12= .83333 (round to .83)

and i would multiply that by his weight which is 165*.83=136.95 mgs per dose?

First of all convert the weight.165 divided by 2.2 is 75.10mg per kg is 750mg.divided by 2 doses is 375mg.

thanks alot for your help. number 4) I did 50mg/500ML = X/175MCG/MINUTE

AND convert the 175mcg/minute to mg ? to mcg/hour and then cross multiply?

Specializes in Acute Care, Rehab, Palliative.

Convert first.50mg is 50 000mcg.Divided by 500mls is 100mcg/ml.175mcg per minute is the order. So 175(what is ordered) divided by 100 (what you have) is 1.75mls/minute.1.75 multiplied by 60 is 105. You would give 105ml/hr

5) aminophylline 300 mg in 500ml d5w is to be infused over 8 hours. you have aminiphyline 1000mg/20ml. How many mls of aminophylline should be added to the bag of D5W ?

1000mg/20 ml = x/300mg?

cross multiply to get mls ?????

8)pediatric patient with CHF. recommended theurpatic dose of digoxin is 20-35 mcg/kg/day. Patient wieghts 44 pounds. Digoxin comes in 0.25mg per ml. What is minimim amount in mls that your patient can receive?

convert 44lbs into KG which is 20kg. And then I have no idea on what to do :(. And number 9 and 10, can someone please guide me through it

idk where to start..

Ratio:proportion method is easiest for these, IMO.

For 9 convert your weight to kg first, figure out how many mg based on that, then divide by three. Those are the three equally divided doses.

75 kg. What formula is best used to figure out mg.

20mg/kg/day (/) 3 = 5/x?
