A nurse is caring for a client who has a new arteriovenous (AV) graft in his left forearm. Which of the following techniques should the nurse use to assess the patency of this graft?
Measure the client's blood pressure to ensure it is higher in the left arm than the right.
Check the brachial and radial pulses of the left arm simultaneously.
Auscultate the antecubital fossa using a Doppler stethoscope.
Auscultate the site for a bruit.
The Correct Answer is D
Choice A reason: Measuring blood pressure di?erences is not a method to assess the patency of an AV graft.
Choice B reason: Checking pulses is important but does not confirm the patency of the AV graft.
Choice C reason: Using a Doppler stethoscope at the antecubital fossa is not the standard method for assessing AV graft patency.
Choice D reason: Auscultating for a bruit at the site of the AV graft is a common and non-invasive way to assess for patency.

Correct Answer is C
Explanation
Choice A reason: Flatened neck veins would suggest dehydration rather than fluid overload.
Choice B reason: The return of skin to previous position when pinched indicates good skin turgor, not fluid overload.
Choice C reason: A significant weight gain in a short period, such as 5 lb since yesterday, is a classic sign of fluid overload.
Choice D reason: An oxygen saturation of 93% does not necessarily indicate fluid overload.
Correct Answer is B
Explanation
Choice A reason: A raised red rash is not typically indicative of venous insufficiency but could suggest an allergic reaction or infection.
Choice B reason: Coldness and numbness distal to the fistula site can indicate poor blood flow, which is a symptom of venous insufficiency.
Choice C reason: Pain proximal to the fistula site can be a sign of venous hypertension and insufficiency, as it may
indicate increased pressure in the veins.
Choice D reason: Foul-smelling drainage is not a typical sign of venous insufficiency but may indicate an infection.
