Please help!!! I have tried it a couple of ways. Asked instructor for help, she said review the chapter (no example of this) and said, "You don't have to use all the info." Whaaat???
I'm thinking order x label x drop factor = flow rate (mL/hr) But there are so many conversions and I... am just LOST!!!
.1mg/kg/min (weighs 100kg) =6mg/kg/hr (still need to factor in the weight)=600mg/hr.
The physician has ordered 600mg/hr, but how many ml is this?
500mg per 70 ml: 500mg/70ml=600mg/xml
600mg per 84 ml.
This is also 1260gtt/hr, or 21gtt/min.
Step I: I get 10mg/kg/min because 100kg multiply by 0.1mg = 10mg then you need to convert to mg/hr and multiply by 60 (60 minutes per hour). 10mg/min X 60min/hr = 600 mg/hr as the min. cross each other out.
I didnt start nursing school yet so i dont have anyone to ask or check if i am right but i believe the answer is 84ml/hr. Im not so sure that Im right because I didnt learn this yet as i have never taken dosage calculation but I can tell you how I fig it out.
I first found out how many kg the patient was. 220/2.2 = 100kg.
Next I did this 0.1mg/1kg=x/100kg x=10kg.....
10mg/1min=x/60min x=60mg
1g/1000mg=x/60mg
60mg=1000mg X=0.06g
0.5g/70ml=0.06g/x
x=84..
i might be wrong at firsti got8.4 so hopeu fig it out
I am not sure how you are figuring this out, but use dimensional analysis Your last line doesn't equal your x=84:confused:
Also, if I follow your last line you would multiply 0.5g X 0.06g divide by 70mL X x leaving you with grams/mL. You need mL/hr for a flow rate.
220lbs/2.2 for 100kg then multiply by 0.1 = 10mg/min
convert to hours: 10mg/min X 60min/hr = 600 mg because min. cross each other out and you are left with mg/hr
600mg per hour now need to figure out mL/hr that is the flow rate.
mL/hr = 70mL/500mg(given to you in the statement) X 600mg/hr (we figured out) = 70mL X 600mg/500mg X hr
The mg cross each other out leaving you with mL/hr.
42000/500= 84mL/hr. I know it is hard to follow when typed out. Hope this helps

Sorry for a delay in my response , but THANK YOU ALL for your help!!! We had 3 chances & I was panicking because I bombed the first 2!
I PASSED IT though!
Now... on to Statistics!
