Answer to Question 1

A
The myocardium is the middle layer of muscle fibers of the heart that contract to pump blood. The endocardium is the lining of the inner surface of the heart chambers, the epicardium is the outer layer of the heart muscle, and the pericardium is the membranous sac that surrounds the heart.

Answer to Question 2

B
The primary reason for increased risk of infection in diabetic patients is the hyperglycemic envi-ronment. Lesser risk factors include atherosclerotic vascular changes, abnormal phagocyte func-tion, and decreased leukocyte function.
