Answer to Question 1

ANS: C
Over 20-30 years, atheromatous plaques (stenotic lesions) form at branchings and curves in the cerebral circulation, primarily the arteries, not in veins, near the sphincters, or in the venous si-nuses.

Answer to Question 2

ANS: C
The most likely contributing factor to the patient's stroke is that he has diabetes with a fourfold increase in stroke incidence and an eightfold increase in stroke mortality. Age greater than 65 years is contributing factor. Men are affected, but for the 30-year-old, his type 2 diabetes mellitus contributes to a fourfold increase in stroke incidence and an eightfold increase in stroke mortali-ty. Blacks are affected more than whites, and it is this patient's diabetes that places him at risk.
