Central Venous Access Device (CVAD) characteristics include which of the following?

• A. are placed in large blood vessels
• B. Allow frequent, continuous, or intermitted administration of chemotherapy, immunotherapy, targeted therapy, and other products
• C. Avoid multiple venipunctures
• D. All of the above

Answer: (D)

Central venous access devices are designed to provide reliable, long-term vascular access by residing in large central veins. This positioning allows administration of drugs that are difficult on peripheral veins, including chemotherapy, immunotherapy, targeted therapy, and other products, often at high volumes or concentrations. Because they sit in central circulation, they support frequent, continuous, or intermittent administration without repeatedly puncturing peripheral veins. This also spares peripheral veins from repeated venipunctures, reducing vein injury and preserving them for future use. Taken together, these characteristics describe CVADs comprehensively, so all of the statements apply.
