Select if the routes of administration listed below are enteral or parenteral.

Subcutaneous: A parenteral route where medication is injected into the tissue layer between the skin and muscle. It bypasses the gastrointestinal (GI) tract, allowing for faster absorption of certain medications like insulin or heparin. NG Tube: A form of enteral administration that delivers medication directly into the stomach via a nasogastric tube. This route utilizes the GI tract and is often used for patients who cannot swallow. Oral: A classic enteral route involving medication taken by mouth and absorbed through the digestive tract. It is the most common and convenient method of drug delivery. Rectal: An enteral route that involves administration of medication into the rectum, where it is absorbed by the lower GI tract. It is often used when oral administration is not feasible. Intramuscular: A parenteral route where medication is injected into a muscle, offering faster absorption than enteral routes. Common for vaccines and certain pain medications. Intravenous: A parenteral route that delivers medication directly into the bloodstream. It provides the most rapid onset of action and is used for critical care, emergencies, and precise dosing.
