Answer 2

2.  Choice A is the correct answer.  An ABI greater than 1.0 is considered normal and an ABI less than 1.0 is consider abnormal and suggestive of peripheral artery disease.  ABI is fairly accurate.  No clinical data suggests that smokers need angiography.  It is a highly invasive procedure with complications and should be reserved for those high risk individuals are those with acute arterial occlusion or those where surgery may be necessary.  Starting patients empirically on Cilostazol is not appropriate.  These medications can cause bleeding and have side effects.
