Correct Answer is C
Explanation
Choice A rationale:
Modified equivalents. This is not the correct answer. The abbreviation "mEq" stands for milliequivalents, not modified equivalents.
Choice B rationale:
Megaequivalents. This is not the correct answer. "Mega" is a prefix indicating a factor of one million. In the context of electrolytes and medications, milliequivalents (mEq) are the appropriate unit of measurement, not megaequivalents.
Choice C rationale:
Milliequivalents. This is the correct answer. Milliequivalents (mEq) are a measure of the chemical combining power of a substance. In medical contexts, mEq is often used to express the amount of electrolytes (such as potassium, sodium, calcium) in a solution or dosage form. It represents 1/1000th of an equivalent, which is the amount of a substance that can react with or replace one mole of hydrogen ions (H+) It is important for healthcare professionals to understand these units when dealing with medications and intravenous fluids, as incorrect administration can lead to serious health complications.
Choice D rationale:
Miniequivalents. This is not the correct answer. "Mini" is not a standard prefix used in the International System of Units (SI) The correct prefix for a thousandth of an equivalent is "milli," making milliequivalents the appropriate unit of measurement for substances like electrolytes.
