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: During the oliguric phase of acute kidney injury, BUN and creatinine levels typically increase, not decrease, due to reduced kidney function.
Choice B reason: Renal function is not reestablished during the oliguric phase; this phase is characterized by decreased function.
Choice C reason: The oliguric phase is defined by significantly reduced urine output, often less than 400 mL per 24 hours.
Choice D reason: The GFR does not recover during the oliguric phase; it is usually decreased.
Correct Answer is C
Explanation
Choice A reason: A diet high in calcium oxalate-rich foods should be avoided as it can contribute to the formation of calcium oxalate stones.
Choice B reason: Continuing prescribed gout medication is important, but it does not directly prevent the formation of renal calculi unless the medication is specifically for reducing uric acid levels.
Choice C reason: Drinking plenty of fluids, especially water, is one of the most effective ways to prevent the recurrence of renal calculi by diluting the urine and reducing the concentration of stone-forming minerals.
Choice D reason: A diet high in purine-rich foods can increase the risk of uric acid stones and should be avoided, especially in patients with gout and a history of renal calculi.
