Math problems

[mariok]

I need help with these two math problems...

The physicians order reads: 1000 ml 0.9% NS with 20 mEq KCL at 75 ml/hr. How many mEQ of KCL will the client receive each hour?

The physicians order reads: 500 ml 0.9% NS with 100 units of insulin at 30ml/hr. How many units of insulin will the client receive each hour?

So what do you think? How have you set up your problems? What answer did you get?

We are happy to guide you if you show what you have so far

How did you set it up? I prefer to use dimensional analysis:

75 ml/hr x 20 mEq KCl/1000 mL = ?? mEq KCl/ hr.

The insulin problem is similar:

100 units insulin/ 500 mL x 30 mL/hr= ?? units insulin/ hr

Another way to look at it is that if this first patient had these fluids at 75cc/hr, how many hours would it take for the entire liter to infuse?

Doing math, you should come up with 13.3 hrs. then divide this amount into 20 to get your answer to how many mEq are infusing per hour. (20/13.3)
