Correct Answer is B
Explanation
A. Enteral: Enteral administration delivers medication directly into the gastrointestinal tract, such as oral or tube feedings. It involves absorption through the digestive system, so it passes through the GI tract.
B. Parenteral: Parenteral routes bypass the digestive tract entirely and include intravenous, intramuscular, subcutaneous, and intradermal injections. This allows for rapid absorption and avoids the effects of first-pass metabolism.
C. Oral: Oral medications are swallowed and absorbed through the gastrointestinal tract, making this an enteral route that passes through the digestive system.
D. Sublingual: Sublingual administration involves placing the medication under the tongue for absorption through the oral mucosa. Although it enters systemic circulation directly, it is still considered part of enteral absorption because it involves the mouth.
