Which of the following terms is commonly associated with intravenous administration?

The term commonly associated with intravenous administration is "parenteral." This term refers to the administration of substances in routes other than the digestive tract, specifically encompassing methods such as intravenous, intramuscular, and subcutaneous routes. Intravenous administration directly delivers medications into the bloodstream, providing rapid onset of action and ensuring that the drug is fully bioavailable.

In contrast, the term “enteral” refers to any medication route that involves the gastrointestinal tract, such as oral or rectal administration. “Oral” is a specific method of enteral administration where medications are taken by mouth. “Inhalation” refers to the delivery of drugs directly into the respiratory system through the airways and is also distinct from parenteral routes.

Understanding these definitions helps clarify why "parenteral" is the correct term associated with intravenous administration.
