Intravenous (IV) administration refers to what type of injection?

  1. Injection into the muscle

  2. Injection into the vein

  3. Injection beneath the skin

  4. Topical application

The correct answer is: Injection into the vein

Intravenous (IV) administration is specifically defined as the injection of substances directly into a vein. This method allows for rapid absorption of the medication or substance into the bloodstream, ensuring that it reaches systemic circulation quickly and with immediate effect. It is commonly used in clinical settings for delivering medications, fluids, or nutrients when a fast response is necessary or when the patient cannot take medications orally. Contrastingly, other methods of injection such as intramuscular or subcutaneous do not involve the direct entry into the bloodstream through a vein, and topical application refers to the application of a substance onto the skin surface, further highlighting the unique nature of IV administration.
