Final answer:
The nurse should auscultate the left arm for a bruit and palpate for a thrill to assess the arteriovenous fistula, and avoid taking blood pressure readings, drawing blood, or starting an IV in the same arm to protect the integrity of the fistula.
Step-by-step explanation:
When assessing a patient who has recently undergone arteriovenous fistula implantation for dialysis, the nurse should auscultate the left arm for a bruit and palpate for a thrill. It is crucial not to draw blood from the arm with the fistula or take blood pressures from that arm, as these actions can damage the fistula. Establishing a new intravenous line in the same extremity is also typically avoided to prevent complications.
This is important to assess the patency and function of the arteriovenous fistula. Drawing blood from the left arm or taking blood pressures from the left arm may interfere with the functioning of the fistula. Starting a new intravenous line in the left lower arm is not necessary unless there is a specific indication to do so.
The arteriovenous fistula is specifically designed to create a high-flow vascular access for hemodialysis, and its integrity is essential for the patient's dialysis treatment. Taking blood pressure with a cuff on the same arm can occlude blood flow and risk thrombosis or damage to the fistula. Similarly, withdrawing blood from the fistula arm can disrupt the delicate balance that has been created for dialysis access. Instead, nurses focus on assessing the patency of the fistula by checking for the presence of a bruit (a sound made by turbulent blood flow) and a thrill (a vibration caused by turbulent flow that can be felt on palpation).
