What are the 5 Parenteral routes of Drug Administration?

The correct answer identifies five parenteral routes of drug administration that are commonly used in emergency medical situations. Parenteral routes refer to any method of delivering medication that bypasses the gastrointestinal tract, offering a more direct absorption into the bloodstream or specific target areas.

Intravenous administration delivers medication directly into the bloodstream, allowing for immediate effects and precise control over the dosage. Endotracheal administration involves delivering medication directly into the trachea, often used for rapid effects in patients unable to take medications through traditional routes, particularly in emergencies. Intramuscular injections provide a means to deliver drugs into a muscle, allowing for faster absorption than subcutaneous administration. Subcutaneous routes deliver medication into the tissue layer between the skin and muscle, designed for gradual absorption. Lastly, inhalation is considered a parenteral route because it enables medication to be delivered directly to the lungs where it can enter the bloodstream quickly, particularly in respiratory emergencies.

The other answer choices include routes that do not fit the definition of parenteral administration. Oral, sublingual, buccal, and rectal methods involve the gastrointestinal tract in some manner, making them non-parenteral routes.
