Which abbreviation stands for microgram?

Which abbreviation stands for microgram?

• A. mEq
• B. mcg
• C. tab
• D. sol/sol'n

Answer: (B)

When dealing with small drug doses, the measurement unit microgram represents one millionth of a gram. The common abbreviation for microgram is mcg, and you’ll also see μg in scientific contexts. Here, mcg is the best fit because it directly stands for microgram and is widely used in medical labeling and pharmacology texts, making it the most recognizable shorthand for this unit. Other options refer to different concepts: mEq stands for milliequivalents, a unit used for electrolytes and chemical equivalents; tab indicates a tablet form; and sol/sol'n stands for a solution. None of those describe a mass unit like microgram, which is why they aren’t correct in this context.
