Which of the following is a critical sign to observe after accessing a CVAD?

• A. Increased peripheral circulation
• B. Signs of infiltration or phlebitis
• C. Increased patient alertness
• D. Reduction in heart rate

Answer: (B)

After accessing a central venous access device (CVAD), one of the critical signs to observe is the presence of signs related to infiltration or phlebitis. Infiltration occurs when the IV fluid or medication leaks into the surrounding tissue, which can cause swelling, pain, and potentially lead to tissue damage if not addressed promptly. Phlebitis, on the other hand, is inflammation of the vein, often resulting in redness, tenderness, and swelling along the vein.

Monitoring for these signs is crucial because they can indicate complications that may arise from the insertion or use of the CVAD, possibly necessitating immediate intervention. Early detection of either condition can help prevent further complications, ensuring the safety and comfort of the patient.

The other options provided do not directly relate to signs that would be critical to monitor following the access of a CVAD. Increased peripheral circulation, for instance, is not a typical concern associated with CVADs and does not indicate a complication. Increased patient alertness may be a positive sign of well-being and could indicate an appropriate response to treatment, but it does not specifically relate to the integrity of the CVAD. A reduction in heart rate, while potentially significant in other clinical situations, does not directly correlate with the monitoring
