I tried DosageHelp. It's too vague for me. A preparing tube feedings question: 25% Nutrivent must be prepared for a tube feeding. You have available full strength Nutrivent. To prepare 400 mL of feeding, you dilute __ mL of the full strength Nutrivent with ___ mL of water. It's questions like these. There's no formula for how to figure out something like that that I've found yet, or one like this "How many g of lidocaine HCl does a patient receive when 45.5 mL of a 0.5% solution is administered?"

Hi, everyone. I'm an LPN student on her first semester. Each semester we'll have a math competency test, and I have no experience with dosing calculations. We've kinda been thrown into it with just two packets with problems to solve, without having it explained how to do them, and I'm someone that has a lot of issues with math (I'm literally having to re-learn long division). Could someone help me out with the proper formulas for finding drug/solutes in solution, preparing feeding tubes, expressing solution strength, and # of tabs, caps, or mL to prepare? I'm kinda running blind here and every website or video I've found so far has different names for all of it, and I can't recognize which one is which.
