Calculation

Hi can anyone help me solve this problem,

1.A hypoglycaemic child who weighs 30kgs is prescribed 0.25g/kg. Using a solution of 10% dextrose what volume is mls is this?

In question no.1 how will I be able to get the volume in mls if it is not indicatEd in the question.

2.The prescription for your patient reads "Using 0.4% of 500 ml of lignocaine bag, give 3 mg/min". In carrying out the order, you set the infusion pump at a rate of Answer
mls/hr?

In this problem, I got 22.5mls/ hr but the answer should have been 45mls/hr.Can anyone show me a different way to solve this pleaaasseee... Last edit by sirI on Jun 4 : Reason: threads merged
What have you calculated so far? Which part is problematic for you?

The first one I can't figure out the question

Would you perhaps use the calculation Volume (in mLs)×gtt (drop factor)__________________________________Time (in minutes)

You're going to get the same answer on this board as you did on the other one. Show us what you've done so we can guide you. Otherwise you aren't learning anything. I have the answers for you but I won't give them to you without seeing what your thought processes are. And neither will anybody else.

It seems that for question 1 you are being thrown by not being provided with the total mL that the total bag contains. Such as 100ml D10NS. I would suggest not getting caught up in small details. No matter the size of the bag the concentration does not change in every 1 mL of solution 10% will be dextrose and 90% solution or simply 0.1g of dextrose in each 1 ml of solution. Now if you know the total amount of dextrose have been ordered. How many mL of solution would be required to achieve the ordered dose?Question 2 works the same way. A 40% solution should have 4 mg of lidocaine for each ml. If the order is 3mg/min how many ml would you give? hint: you should know it would be less than 1 ml/min. Finally multiply by 60 min to convert to ml/hr.
