Intravenous (IV) refers to the administration of medication or fluids directly into a vein.
Suffixes are word endings that modify the meaning of a word.
Therefore, it's likely that you're looking for a word related to intravenous administration that ends in a specific suffix. To help me understand what you're looking for, please provide more context or specify the suffix you're interested in.
For example, you might be looking for:
* Intravenous medications ending in "-ine": Examples include adrenaline, dopamine, and morphine.
* Intravenous procedures ending in "-ectomy": While "ectomy" usually refers to surgical removal, there are no standard procedures that end in this suffix and are administered intravenously.
Please clarify your request, and I can provide a more specific answer.
