Help with reconstitution problem

[alisant]

Hello! I think I understand the math portion of the question (I could be wrong), but I'm not exactly sure how to apply my answers. Here's an example:

Explain how you would prepare the following from ready-to-use oral nutritional formulas.

1) Prepare 5/8 strength of 8 fl oz of Ensure

How much Ensure? (mL)

How much water? (mL)

For my answers, I got 150 mL and 90 mL. I don't know which is water and which is Ensure. I thought there was always more water than powder--does that go for every reconstitution?

Another example...

Explain how you would prepare the following from ready-to-use Enteral nutritional formuals.

1)Administer 3/4 strength Sustacal 360 mL over 4 h via gastrostomy tube.

How much Suctacal? (mL)

How much water? (mL)

I'm not even really sure what is being asked here.

Thanks so much for your help!

to avoid not knowing which number is which, you might want to try dimentional analysis, it made a huge difference for me.

someone posted this site for me and i loved it. http://susanp3.tripod.com/snurse/id28.htm

i'm not even really sure what is being asked here. it is asking you how to prepare, so the "over 4hr via gtube" is extra information. figure it the same as the first one, 3parts sustacal to 1 part water.

thanks so much for your help!
