Why are CVADs preferred for drug administration in some cases?

• A. They are more visible
• B. They provide immediate access to large veins
• C. They are less expensive
• D. They are used primarily for short procedures

Answer: (B)

The preference for Central Venous Access Devices (CVADs) for drug administration is largely due to their ability to provide immediate access to large veins. This access enables healthcare providers to deliver medications, fluids, or blood products directly into the central circulation, which is particularly beneficial in various clinical situations. For instance, medications that require rapid action or those that are irritants to smaller veins can be administered more effectively through large central veins. Additionally, CVADs are capable of accommodating high-volume infusions and can remain in place for an extended period, making them ideal for patients needing long-term treatment or frequent access for interventions. In contrast, visibility is not a primary factor in the selection of CVADs for drug administration, as these devices are typically placed beneath the skin, making them less visible than peripheral devices. Cost considerations vary based on the setting and specific circumstances of patient care, and while short procedures may utilize different types of access devices, CVADs are commonly employed for both short-term and long-term therapeutic needs.
