Second Question:A milliequivalent (mEq) is a unit of measurement that is used in medicine and chemistry to express the concentration of ions in a solution. It is a measure of the amount of a particular ion in a solution, relative to the number of ions in a mole of that compound.
One milliequivalent is equal to one-thousandth (1/1000) of an equivalent, where an equivalent is the amount of a substance that can react with or replace one mole of hydrogen ions (H+).
Milliequivalents are commonly used to measure the concentration of electrolytes, such as sodium, potassium, chloride, and calcium, in the blood or other body fluids. By expressing concentrations in milliequivalents, healthcare providers can better understand and manage electrolyte imbalances and other conditions related to ion concentrations in the body.
