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: CAPD can be suitable for clients with a history of abdominal surgery, but it is not specifically the
treatment of choice due to this reason alone.
Choice B reason: CAPD does not require a rigid schedule of exchange times. It is ?exible and can be adjusted to fit the client's lifestyle.
Choice C reason: CAPD allows for more dietary and fluid freedom compared to hemodialysis because it is a continuous process that removes waste products and excess fluid more gradually.
Choice D reason: CAPD does not filter the client's blood through an artificial device called a dialyzer; that is a description of hemodialysis. CAPD uses the client's peritoneum as the filter to remove waste products and excess fluid.
Correct Answer is A
Explanation
Choice A reason: Metastasis refers to the process by which cancer cells spread from the primary tumor site to distant organs or tissues. This can occur through the bloodstream or lymphatic system, leading to the formation of secondary tumors in other parts of the body.
Choice B reason: This statement is incorrect because metastasis, by definition, involves the spread of cancer cells to multiple locations, not their confinement to a single area.
Choice C reason: The description provided in this choice is more indicative of metaplasia, which is a change in the type of cells, and not metastasis, which is the spread of cancer cells.
Choice D reason: This choice is incorrect as it does not describe metastasis. Cancer cells do not stop growing because they run out of space; they continue to proliferate and can invade other tissues.
