What should be monitored to ensure the proper functioning of a CVAD?

• A. Patient's emotional response
• B. Catheter insertion site and blood return
• C. Catheter color and length
• D. Frequency of medication administration

Answer: (B)

Monitoring the catheter insertion site and blood return is crucial for ensuring the proper functioning of a Central Venous Access Device (CVAD). The insertion site should be regularly assessed for signs of infection, such as redness, swelling, or drainage, as these can indicate complications. Additionally, evaluating blood return is essential, as it confirms that the catheter is patent (open) and functioning correctly. A lack of blood return can suggest occlusion or displacement of the catheter, requiring immediate investigation or intervention to prevent complications.

While assessing the patient's emotional response may be important for overall care, it does not directly relate to the functionality of the CVAD. Monitoring catheter color and length provides little relevant clinical information regarding its performance or complications that could arise. Finally, while tracking the frequency of medication administration is important for medication management, it does not address the key elements related to the mechanical function of the CVAD itself. Thus, observing the catheter insertion site and ensuring appropriate blood return are primary indicators of a CVAD’s proper functioning.
