Final answer:
Intermittent claudication is a symptom that can indicate atherosclerosis.
Step-by-step explanation:
The assessment data that would cause the nurse to suspect the client has atherosclerosis is intermittent claudication.
Intermittent claudication refers to the leg pain that occurs when walking and is caused by decreased blood flow due to narrowed arteries. In the case of atherosclerosis, plaque buildup in the arteries restricts blood flow and can lead to the symptom of intermittent claudication. Therefore, if a client presents with complaints of leg pain during walking, it can be a strong indication of atherosclerosis.
