Phosphate Dosing - Units and Terminology Confusion

A previous discussion was about selecting a phosphate repletion product.  Selecting a drug product can be confusing because of the similar names of the various formulations - which are not interchangeable.  Harm can come if one is unaware of the other electrolytes (sodium and potassium) that are necessarily included in the phosphate salt drug.  This discussion aims to clarify further confusion that is possible with regards to terminology and also units (and yes, we'll include just a bit of math).  We will also give a clear example where a published trial could lead someone to a wrong conclusion if they do not mind their units.
