What is the meaning of "mcg" in medication notation?

  1. Capsule

  2. Hour(s)

  3. Microgram

  4. Milliliter

The correct answer is: Microgram

In medication notation, "mcg" stands for microgram. A microgram is a unit of mass equal to one millionth of a gram. It is commonly used to measure very small amounts of medication, making it important for medication aides to understand this abbreviation when administering medications to ensure the correct dosage is given to the patient. Option A, "Capsule," refers to a solid dosage form of medication. Option B, "Hour(s)," refers to time measurement. Option D, "Milliliter," refers to a unit of volume. These options are not relevant to the abbreviation "mcg" in medication notation, making them incorrect choices for this question.
