By which of the following routes are drugs administered directly into the bloodstream?

  1. Enteral

  2. Transdermal

  3. Transmucosal

  4. Intravenous

The correct answer is: Intravenous

Drugs can be administered through different routes, such as orally (enteral), through the skin (transdermal), through mucous membranes (transmucosal), or directly into the bloodstream (intravenous). While all of these routes eventually lead to the bloodstream, the only route that directly administers drugs into the bloodstream is intravenous. This is because the drug is injected directly into a vein, bypassing the digestive system, skin, and mucous membranes. This allows for a faster and more efficient delivery of the drug. Choosing any of the other options would result in a longer absorption time and potential loss of potency of the drug.
