The nurse is assessing a client with a presumptive diagnosis of peripheral arterial disease. The nurse obtains an Ankle-Brachial index of 0.89. Which intervention should the nurse take next?

A bruit is a sound that can be heard with a stethoscope when blood flows through a narrowed or damaged artery. An abdominal bruit may indicate an abdominal aortic aneurysm (AAA), which is a bulge or swelling in the main blood vessel that runs from the heart down through the chest and tummy.

Shortness of breath is a common symptom of many conditions, but it is not specific to AAA. It can be caused by heart or lung problems, anemia, anxiety, lack of exercise, obesity, and many other factors. Shortness of breath may occur with a ruptured AAA, but it is not a reliable sign of an intact AAA.

Ripping abdominal pain is a severe and sudden pain that may indicate a ruptured AAA, which is a life-threatening situation that requires immediate medical attention. However, an intact AAA usually does not cause any pain or discomfort. Therefore, ripping abdominal pain is not a good indicator of an AAA diagnosis.

Decreased urinary output is a sign of reduced kidney function, which can have many causes such as dehydration, kidney failure, urinary tract obstruction, or medication side effects. Decreased urinary output is not directly related to AAA, although it may occur as a complication of a ruptured AAA or surgery to repair an AAA.

The nurse should prioritize notifying the surgeon and anesthesiologist as the first action. The absent pulses, coolness, and mottled appearance of the leg indicate potential compromised blood flow to the lower extremity, which could be a sign of vascular compromise or acute limb ischemia. These findings are concerning after the repair of an abdominal aortic aneurysm and require immediate medical attention.

Wrap both legs in a warming blanket: While it is important to maintain the client's body temperature, this action alone may not address the underlying issue of compromised blood flow and potential limb ischemia. Notifying the surgeon and anesthesiologist is the priority to address the immediate concern.

Compare findings to the preoperative assessment of the pulses: While comparing findings to the preoperative assessment is important for evaluating the client's condition, it should not delay immediate action. The priority in this situation is to promptly notify the surgeon and anesthesiologist to address the potential vascular compromise.

Document the findings and recheck in 15 minutes: Documenting the findings is an important step in the nursing process, but it should not take precedence over immediate intervention. The concerning signs of absent pulses, coolness, and mottled appearance require urgent attention, and delaying notification could lead to further complications.
