Med Math Help

Hi Guys,

Sorry to keep bothering you all with my questions but I'm really having a hard time. I'm not looking for all the answers I just kind of need help starting. I'm not sure if we're missing information or if I've just drawn a blank and that's why I can't figure out how to do this problem. So, below is all the information I've been provided with ...

Actually I've attached our document since it won't let me copy and paste.

Thanks in advance for your help!!!

Sorry there is not enough information provided in the attachment for anyone to offer any advice. Would need to know what the starting dose is and what the sliding scale for the adjustment of the hourly blood glucoses.

I suspect this is what algorithm one and the link that will not open refers to.

Here, try this link with the alogrithms in it:

Basically, you need to add or substract insulin according to BG readings, and this chart will tell you by how much. Remember, it's how much you add or subtract from the previous number...

This does answer the sliding scale part - but you would still need a starting dose. For example a pt is admitted to your unit with a provider order of Insulin infusion at ??units/hr and titrated by algorithm one.

Thus at 1100 with a BG of 300 you know that you would need to increase their current insulin infusion by 3 1/2 units/hr -- BUT to answer the question you would have to know what the total infusion rate was prior to 1100 in order to increase it by 3.5 units.

That's what I was wondering .. I think we are missing a starting dose and therefore we cannot complete it. Last week we were given a similar problem but it gave it a starting dose and we were able to calculate it that way. From other's I've spoken to they stated we do not need to add or subtract anything at the moment .. that the answers would be as follows:

3.5 units/hr

4 units/hr

2.5 units/hr

1.5 units/hr

3 units per hour

3 units per hour

2.5 units per hour

and the ml/hr would be double of each of those.

If that's the case that's a super simple solution to the answer but last week we had to either add or subtract in our problem, so, I'm not sure. sigh!

I'll post on here what it is that the instructor was looking for after class tomorrow .. we do go over these in class eventually but they're supposed to be finish before class starts. Thanks for the help guys!!

On my phone right now thus not looking at the problem. It could be just that simple as to recognize what the bs is how many additional units you would need to infuse during that hour. But didn’t the question also want you to answer how many ml/hr? Then you one additional step to calculate.
