Answer:
50%; 50 percentage of the arterial lumen must be obstructed before intermittent claudication is experienced
Explanation:
Intermittent claudication refers to an aching pain in the legs when walking or exercising that goes away when resting. The pain may affect your: calf, hip, thigh, buttock, arch of the foot.
Intermittent claudication is a common early symptom of PAD. It’s caused by a blockage or obstruction of the arteries that supply blood to your legs and elsewhere peripherally.
For intermittent claudication to occur or be experienced, about 50% of the arterial lumen or 75% of the cross-sectional area must be obstructed or blocked.
Therefore, the answer the student should give is 50%.
