nursing math world problem (need help ASAP)

153/2.2= 69.55 kg

69.55 x 0.17 = 11.82 units

Now, here is where I run into a problem. Is she supposed to recieve these 11.82 units before each meal? Or is that supposed to be her total for the day? I dont understand this part of the question: "The patient is to receive her insulin in three evenly-sized doses right before each meal."

Does the question say anythign about 0.17 units/kg/day?

I have been driving myself crazy for hours trying to figure this problem out! Any help with this would be greatly appreciated. The question is: Suppose you need to administer 0.17 units of insulin per kilogram of body weight on a patient. The patient weighs 153 pounds. Your insulin supply reads "insulin: 100 units per mL". The patient is to receive her insulin in three evenly-sized doses right before each meal. a.) How many units of insulin are needed? b.) How many is that per meal? c.) How many mL do you draw from the supply vial each time? The farthest I have gotten with this is turning the patients weight into kg and from there I have been completely lost! PLEASE HELP

Ok, so you know that you need to convert your pounds to kg. That's step 1.

So now that you've done that, you know you are to administer 0.17 units per kg. So your weight in kilograms multiplied by 0.17 units/kg- the kg cancel each other out and you are left with your dose in units.

So now you know your dose in units- your insulin is supplied as 100 units/mL so what do you do to your unit dose to figure out how many mL you administer? (I actually think this is kind of a stupid part to this question, since insulin syringes are labeled in units, not mL.)

This is also a badly-worded question because it could be read as giving three doses before each meal, rather than one dose before each of three meals.

However, you figure out the dose the same way.

Number of kilograms x the amount of drug per kg desired gives you the total dose.

Divide that by three.

Done.
