Question

cancer chemotherapy is often toxic, and therefore is not generally delivered through skin and muscle tissue, which can be damaged by the treatment. during chemotherapy, a clinician will often use an intravenous port that is surgically placed under the skin, leading to a central venous line, to deliver drugs directly into the bloodstream. in other clinical situations, intravenous ports can be used to deliver antibiotics or to perform blood transfusions. delivery of a drug via an intravenous port is an example of _______ route of administration. a transdermal a parenteral a topical an enteral

Explanation:

1. Recall the definitions of each route:

• Transdermal: Through the skin (e.g., patches). The problem states chemotherapy isn't delivered through skin, so this is incorrect.
• Parenteral: Administration outside the digestive tract, including intravenous (IV) routes. Intravenous port delivery is IV, so this fits.
• Topical: Applied to a surface (e.g., skin, mucous membranes). Not applicable here.
• Enteral: Through the digestive tract (e.g., oral, gastric). IV isn't enteral.

Answer:

B. a parenteral
