Question

A nurse is caring for a client receiving hemodialysis who has an internal arteriovenous (AV) fistula. Which assessment finding would indicate to the nurse that the fistula is patent?

a) white fibrin specks noted in the fistula
b) palpation of a thrill over the site of the fistula
c) lack of bruit over the site of the fistula
d) a feeling of warmth at the site of the fistula

Answer 1

Palpation of a thrill over the site of the fistula indicates that the fistula is patent.

Step-by-step explanation:

The assessment finding that would indicate to the nurse that the internal arteriovenous (AV) fistula is patent is palpation of a thrill over the site of the fistula.

A thrill is a vibration or buzzing sensation that can be felt over the fistula site when there is adequate blood flow through the fistula.

The other options listed in the question would not indicate that the fistula is patent. White fibrin specks, lack of bruit, and a feeling of warmth at the site are not reliable indicators of fistula patency.
