The nurse is caring for a client receiving hemodialysis three times weekly. The client has had surgery to form an arteriovenous fistula. What is most important for the nurse to be aware of when providing care for this client?

Choice A reason: Auscultating the fistula with a stethoscope is not contraindicated; it is a mandatory assessment. The nurse must listen for a bruit, which is the sound of turbulent blood flow. The presence of a bruit, along with a palpable thrill, confirms that the arteriovenous fistula is patent and functioning correctly for hemodialysis access. Choice B reason: Protection of the vascular access is paramount. Taking a blood pressure reading, performing venipunctures, or starting intravenous lines on the affected arm can cause compression, thrombosis, or collapse of the fistula. These actions jeopardize the client's "lifeline" for dialysis and can lead to permanent loss of the access site. Choice C reason: Clients rarely feel best immediately after dialysis. Hemodialysis often causes "dialysis disequilibrium" or post-dialysis fatigue due to rapid shifts in fluid, electrolytes, and urea. Clients frequently report feeling exhausted, washed out, or dizzy immediately following a four-hour treatment session as their bodies adjust to the sudden physiological changes. Choice D reason: While the goal is to minimize discomfort, it is incorrect to say the client "should not" feel pain. Initiation of dialysis involves the insertion of two large-bore needles (usually 15 to 17 gauge) into the fistula. This process is inherently painful or uncomfortable, though many chronic patients develop a high tolerance for the sensation over time.
