What are common reasons for placing a CVAD?

• A. Frequent blood sampling, unstable blood pressure
• B. Peripheral veins are no longer adequate, vesicant drug administration
• C. Patient preference, comfort
• D. Short term IV therapy only

Answer: (B)

The placement of a Central Venous Access Device (CVAD) is often necessary when peripheral veins are insufficient for certain medical needs. One significant reason for choosing a CVAD is that the peripheral veins are often inadequate due to various factors, such as previous use, disease processes, or patients with challenging venous access. Additionally, CVADs are particularly suitable for administering vesicant drugs, which can cause severe tissue damage if they leak into the surrounding tissue. Using a CVAD to administer these powerful medications helps ensure that they are delivered safely and effectively into the central venous system, where blood flow can dilute the drug quickly, minimizing potential side effects. The other choices do not encompass the full range of appropriate indications for using a CVAD. While frequent blood sampling and unstable blood pressure can sometimes justify a CVAD, they are not the primary reasons for its placement. Patient preference for comfort may be a consideration but does not constitute a medical necessity for a CVAD. Short-term IV therapy is generally better suited to peripheral lines, as CVADs tend to be reserved for more complex or prolonged treatment strategies.
