the magic formulas ✨🍷🎩 Flashcards
the magic tube feeding dilution formula
- mL of container / x (which is the total volume, what we are looking for) = strength ordered
- total volume - container = mL of diluent!
the magic body surface area formula
√ (lbs ⋅ inches / 3131) = m2!
the desired over have dosage calculation formula
(desired / have) ⋅ quantity = dosage to be administered
what is the difference between the (desired/have ⋅ quantity) method and dimensional analysis in the context of dosage calculations?
(desired/have ⋅ quantity) method is good for figuring out how many _____ per dose, while dimensional analysis is best for converting lots of units into the one you need.
the mEq formula
(mg of substance/molecular weight of said substance) ⋅ valence = mEq
what is a mEq/L?
mEq/L is a unit of measurement that tells how many electrically charged ions are in a liter of solution. the “equivalent” part stems from how many ions would be needed to replace/have the same chemical effect as one mole of H+ or one mole of OH-.
