3. Which of the following mechanisms can facilitate the development of diverticulosis into diverticulitis?

Correct answer: D

Rationale: The correct answer is D. Undigested food blocking the diverticulum can lead to bacterial invasion, causing inflammation and turning diverticulosis into diverticulitis. Choices A, B, and C do not directly facilitate the development of diverticulitis. Choice A involves a different mechanism related to laxative use, choice B describes a complication of chronic constipation but does not necessarily lead to diverticulitis, and choice C refers to a different condition involving herniation of the intestinal mucosa.

4. During the first few days of recovery from ostomy surgery for ulcerative colitis, which of the following aspects should be the first priority of client care?

5. A client with liver dysfunction is having difficulty with protein metabolism. The nurse anticipates that the results of which of the following serum laboratory studies will be elevated?

Correct answer: B

Rationale: During deamination of proteins, the liver splits the amino group from the carbon-containing compound, which results in the formation of ammonia and a carbon residue. The liver then converts the toxic ammonia substance into urea, which can be excreted by the kidneys. Clients with liver dysfunction may have high serum ammonia levels as a result.
