When an AV fistula lacks a thrill and bruit, what is the most appropriate nursing action?

• A. Notify the provider and withhold use
• B. Proceed with cannulation anyway
• C. Massage the site
• D. Apply heat

Answer: (A)

The key idea is that the absence of a thrill and bruit over an arteriovenous fistula means blood flow through the access may be compromised, raising concern for occlusion or thrombosis. In this situation, the safest and most appropriate nursing action is to notify the provider and withhold the fistula from use for dialysis. This pause prevents further disruption of a potentially occluded access and allows prompt medical assessment and possible intervention to salvage the fistula. While awaiting further orders, assess the distal limb for signs of ischemia, and avoid actions that could worsen the situation—do not cannulate, massage the site, or apply heat. These steps protect the patient and the access until a definitive plan is established.
