What is the recommended needle gauge for accessing a CVAD?

• A. A 10 mL or larger syringe
• B. A 5 mL syringe
• C. A 20-gauge needle
• D. A 14-gauge needle

Answer: (A)

The recommended choice for accessing a Central Venous Access Device (CVAD) is a 10 mL or larger syringe. When working with CVADs, the use of larger syringes is crucial because it helps to ensure smooth and safe medication and fluid administration. The lower pressure generated by a larger syringe minimizes the risk of trauma to the catheter and the vascular access site. Additionally, larger syringes are less likely to generate a vacuum effect, which is important for preventing complications such as catheter dislodgement or damage to the catheter itself. In the context of administering medications or drawing blood from a CVAD, using a syringe with a volume less than 10 mL can increase the risk of complications, as the pressure dynamics can lead to issues with the integrity of the catheter. Thus, the size and type of syringe directly influence the safety and effectiveness of the procedures conducted through a CVAD. This understanding is essential for healthcare providers to maintain best practices in patient care when dealing with these devices.
