Calculation help PLEASE....................

Published

I don't understand how to do this calculation.....HELP!!! I've read threads that we don't have to know Dopamine calculations but this problem was on the ncbn website so I'm worried ones like it are going to be on the test. Is this true and if it is....can someone help me solve this problem please?

The nurse is caring for a client who has a prescription for an Intropin (Dopamine) drip for 5mcg/kg/min.

The client weighs 200 pounds. The nurse has 400 mg per 500 ml D5W available . How many ml should the nurse administer to the client each hour?

THANK YOU!!

The formula to solve this type of problem is:

(dose * weight * 60) / concentration

Remember that you need to convert weight and concentration to the same units that were specified in the original order.

I hope this information is helpful. :specs:

Hi!

I just want to know also if I know how to solve this.Please can you show your computation on this problem?

5 mcg be converted to mg

200 lbs. converted to kg.

Then I arrived at this number 34ml each hour.

I'm not sure if this is correct.

I came up with 34 mls as well.

200 #s = 91 kg

0.005mg (change mcg to mg, there are 1000mcg in 1 mg)

60 sec =1min

on hand just divide (can't go back to see numbers, should have done quick post) I believe was 400/500 = 0.8mg/ml

Multiply 91*0.005=0.455

Multiply 0.455*60=27.3

Divide 27.3/0.8=34.125 or 34mls
