What does "IM" stand for in the context of medicinal administration?

1. Intranasal

2. Intravenous

3. Intramuscular

4. Intradermal

The correct answer is: Intramuscular

In the context of medicinal administration, "IM" stands for "Intramuscular." This method involves delivering medication directly into a muscle, which allows for relatively quick absorption into the bloodstream. Intramuscular injections are commonly used for vaccines, hormones, and certain medications that require rapid systemic effects or larger volumes than can typically be administered subcutaneously. The other options represent different routes of administration: "Intranasal" refers to delivery through the nasal mucosa, "Intravenous" involves administration directly into a vein for immediate effect, and "Intradermal" is the injection into the dermal layer of the skin, often used for allergy tests or tuberculosis screening. Each route has its specific uses and advantages, depending on the desired effect and the characteristics of the medication being administered.
