The abbreviation 'IM' stands for which term?

• A. IM
• B. At bedtime
• C. Microgram
• D. Intramuscular

Answer: (D)

Understanding how meds are given relies on familiar abbreviations for routes of administration. IM stands for intramuscular, a route where the drug is injected into a muscle. This approach allows medicine to be absorbed relatively quickly through muscle tissue, faster than subcutaneous injections but typically slower than IV administration, depending on the preparation and site. Common injection sites include the deltoid and gluteal muscles. Recognize that other options address different concepts—microgram is a unit of dose (often written mcg), and “at bedtime” is a timing instruction, not a route. So the term represented by IM is intramuscular.
