Answer to Question 1

B
Most diverticula are asymptomatic, uncommon in people under age 50, and almost universal in those over 90 . Increases in intra-abdominal pressure from constipation and straining to defecate causes herniation of the mucosa through the bowel wall, causing a small pocket in the colon.

Answer to Question 2

D
The purple hue in the new stoma is an indication of reduced perfusion to the stoma and should be reported immediately. A new stoma should have a pink or beefy red color, be slightly edematous, and have some small bleeding around the stoma.
